Background

As you all know, charts are the graphical representations of our data. It is much easier to understand our data if it is in a graphical form. Am I right? It is easy to create a static chart, but what about a dynamic one? It will be bit tough right? But by using Spire.XLS, we can create any kind of charts easily. In this post, we will see those implementations.

Download the files

You can always get the needed files from here: Download Spire.XLS

Install Spire.XLS

I am using evaluation version with one month temporary license. There are free versions also available for spire.xls with some limitation. You can try that. Now click on the exe file after you extract the downloaded file. The installation will get started then.

Using the code

Before starting with coding you need to add the needed namespaces as follows.

[csharp]
using Spire.Xls;
using System.Drawing;
[/csharp]

First of all create a form and then a button, in the button click add the following lines of codes.

C# Code

[csharp]
private void button1_Click(object sender, EventArgs e)
{
try
{
//Create a new workbook
Workbook workbook = new Workbook();
//Initialize worksheet
workbook.CreateEmptySheets(1);
Worksheet sheet = workbook.Worksheets[0];
//Set sheet name
sheet.Name = "Chart data";
//Set the grid lines invisible
sheet.GridLinesVisible = false;
//Create a chart
Chart chart = sheet.Charts.Add(ExcelChartType.Pie3D);
//Set region of chart data
chart.DataRange = sheet.Range["B2:B5"];
chart.SeriesDataFromRange = false;
//Set position of chart
chart.LeftColumn = 1;
chart.TopRow = 6;
chart.RightColumn = 9;
chart.BottomRow = 25;
//Chart title
chart.ChartTitle = "Sales by year";
chart.ChartTitleArea.IsBold = true;
chart.ChartTitleArea.Size = 12;
//Initialize the chart series
Spire.Xls.Charts.ChartSerie cs = chart.Series[0];
//Chart Labels resource
cs.CategoryLabels = sheet.Range["A2:A5"];
//Chart value resource
cs.Values = sheet.Range["B2:B5"];
//Set the value visible in the chart
cs.DataPoints.DefaultDataPoint.DataLabels.HasValue = true;
//Year
sheet.Range["A1"].Value = "Year";
sheet.Range["A2"].Value = "2002";
sheet.Range["A3"].Value = "2003";
sheet.Range["A4"].Value = "2004";
sheet.Range["A5"].Value = "2005";
//Sales
sheet.Range["B1"].Value = "Sales";
sheet.Range["B2"].NumberValue = 4000;
sheet.Range["B3"].NumberValue = 6000;
sheet.Range["B4"].NumberValue = 7000;
sheet.Range["B5"].NumberValue = 8500;
//Style
sheet.Range["A1:B1"].Style.Font.IsBold = true;
sheet.Range["A2:B2"].Style.KnownColor = ExcelColors.LightYellow;
sheet.Range["A3:B3"].Style.KnownColor = ExcelColors.LightGreen1;
sheet.Range["A4:B4"].Style.KnownColor = ExcelColors.LightOrange;
sheet.Range["A5:B5"].Style.KnownColor = ExcelColors.LightTurquoise;
//Border

sheet.Range["A1:B5"].Style.Borders[BordersLineType.EdgeTop].LineStyle = LineStyleType.Thin;
sheet.Range["A1:B5"].Style.Borders[BordersLineType.EdgeBottom].Color = Color.FromArgb(0, 0, 128);

sheet.Range["A1:B5"].Style.Borders[BordersLineType.EdgeLeft].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:B5"].Style.Borders[BordersLineType.EdgeLeft].LineStyle = LineStyleType.Thin;
sheet.Range["A1:B5"].Style.Borders[BordersLineType.EdgeRight].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:B5"].Style.Borders[BordersLineType.EdgeRight].LineStyle = LineStyleType.Thin;
//Number format
sheet.Range["B2:C5"].Style.NumberFormat = "\"$\"#,##0";
chart.PlotArea.Fill.Visible = false;
//Save the file
workbook.SaveToFile("Sample.xls");
//Launch the file
System.Diagnostics.Process.Start("Sample.xls");
}
catch (Exception)

In the above lines code, we are creating a pie chart by giving some settings and data and load it. Now if you run you will get an output as follows.

In the above mentioned lines of codes, we are doing so many processes, those processes are listed below.

Wow!. That’s cool right?

Not yet finished!. There are so many things you can try with your sheet object. I suggest you to try those. You will get surprised.

Working With Charts Using Spire XLS Sheet Object

Working With Charts Using Spire XLS Sheet Object

If you want you can set different chart types too, it will give you a great design in your chart. The most useful chart types which I uses is Bar3DClustered, 3DBubble, Bubble, Column3D and many more.

Working_With_Charts_Using_Spire_XLS_Chart_Object

This product gives you many ways to make your chart in the way you like. There are plenty of options available to so so like you can set the Legend Position by using LegendPositionType property.

Next we will see how we can implement Column chart, what ever we have discusses will be same for every charts, but it may have some different properties which is strictly depends on the chart type.

Column Chart

Now we will create an another button and name it Column Chart. And in the button click you need to add the following codes.

C# Code

[csharp]
private void button2_Click(object sender, EventArgs e)
{
try
{
//Load Workbook
Workbook workbook = new Workbook();
workbook.LoadFromFile(@"D:\Sample.xlsx");
Worksheet sheet = workbook.Worksheets[0];
//Add Chart and Set Chart Data Range
Chart chart = sheet.Charts.Add(ExcelChartType.ColumnClustered);
chart.DataRange = sheet.Range["D1:E17"];
chart.SeriesDataFromRange = false;
//Chart Position
chart.LeftColumn = 1;
chart.TopRow = 19;
chart.RightColumn = 8;
chart.BottomRow = 33;
//Chart Border
chart.ChartArea.Border.Weight = ChartLineWeightType.Medium;
chart.ChartArea.Border.Color = Color.SandyBrown;
//Chart Title
chart.ChartTitle = "Parts Sales Info";
chart.ChartTitleArea.Font.FontName = "Calibri";
chart.ChartTitleArea.Font.Size = 13;
chart.ChartTitleArea.Font.IsBold = true;
//Chart Axes
chart.PrimaryCategoryAxis.Title = "Parts";
chart.PrimaryCategoryAxis.Font.Color = Color.Blue;
chart.PrimaryValueAxis.Title = "Amounts";
chart.PrimaryValueAxis.HasMajorGridLines = false;
chart.PrimaryValueAxis.MaxValue = 350;
chart.PrimaryValueAxis.TitleArea.TextRotationAngle = 90;
//Chart Legend
chart.Legend.Position = LegendPositionType.Right;
//Save and Launch
workbook.SaveToFile("ExcelColumnChart.xlsx", ExcelVersion.Version2010);
System.Diagnostics.Process.Start("ExcelColumnChart.xlsx");

}
catch (Exception)
{

throw;
}
}
[/csharp]

VB.NET Code

[vb]
‘Load Workbook
Dim workbook As New Workbook()
workbook.LoadFromFile("E:\Sample.xlsx")
Dim sheet As Worksheet = workbook.Worksheets(0)
‘Add Chart and Set Chart Data Range
Dim chart As Chart = sheet.Charts.Add(ExcelChartType.ColumnClustered)
chart.DataRange = sheet.Range("D1:E17")
chart.SeriesDataFromRange = False
‘Chart Position
chart.LeftColumn = 1
chart.TopRow = 19
chart.RightColumn = 8
chart.BottomRow = 33
‘Chart Border
chart.ChartArea.Border.Weight = ChartLineWeightType.Medium
chart.ChartArea.Border.Color = Color.SandyBrown
‘Chart Title
chart.ChartTitle = "Parts Sales Info"
chart.ChartTitleArea.Font.FontName = "Calibri"
chart.ChartTitleArea.Font.Size = 13
chart.ChartTitleArea.Font.IsBold = True
‘Chart Axes
chart.PrimaryCategoryAxis.Title = "Parts"
chart.PrimaryCategoryAxis.Font.Color = Color.Blue
chart.PrimaryValueAxis.Title = "Amounts"
chart.PrimaryValueAxis.HasMajorGridLines = False
chart.PrimaryValueAxis.MaxValue = 350
chart.PrimaryValueAxis.TitleArea.TextRotationAngle = 90
‘Chart Legend
chart.Legend.Position = LegendPositionType.Right
‘Save and Launch
workbook.SaveToFile("ExcelColumnChart.xlsx", ExcelVersion.Version2010)
System.Diagnostics.Process.Start("ExcelColumnChart.xlsx")

[/vb]

Now if you run the code, you can see an output as follows.

Excel Bar Chart

Before going through you must add an new namespace as follows.

[csharp]
using Spire.Xls.Charts;
[/csharp]
Now we will create an another button in our form and in the click event we will write the receding lines of codes.

[csharp]
private void button1_Click(object sender, EventArgs e)
{
try
{
Workbook workbook = new Workbook();
//Initailize worksheet
workbook.CreateEmptySheets(1);
Worksheet sheet = workbook.Worksheets[0];
sheet.Name = "Chart data";
sheet.GridLinesVisible = false;
//Writes chart data
CreateChartData(sheet);
//Add a new chart worsheet to workbook
Chart chart = sheet.Charts.Add();
//Set region of chart data
chart.DataRange = sheet.Range["A1:C5"];
chart.SeriesDataFromRange = false;
//Set position of chart
chart.LeftColumn = 1;
chart.TopRow = 6;
chart.RightColumn = 11;
chart.BottomRow = 29;
chart.ChartType = ExcelChartType.Bar3DClustered;
//Chart title
chart.ChartTitle = "Sales market by country";
chart.ChartTitleArea.IsBold = true;
chart.ChartTitleArea.Size = 12;
chart.PrimaryCategoryAxis.Title = "Country";
chart.PrimaryCategoryAxis.Font.IsBold = true;
chart.PrimaryCategoryAxis.TitleArea.IsBold = true;
chart.PrimaryCategoryAxis.TitleArea.TextRotationAngle = 90;
chart.PrimaryValueAxis.Title = "Sales(in Dollars)";
chart.PrimaryValueAxis.HasMajorGridLines = false;
chart.PrimaryValueAxis.MinValue = 1000;
chart.PrimaryValueAxis.TitleArea.IsBold = true;
foreach (ChartSerie cs in chart.Series)
{
cs.Format.Options.IsVaryColor = true;
cs.DataPoints.DefaultDataPoint.DataLabels.HasValue = true;
}
chart.Legend.Position = LegendPositionType.Top;
workbook.SaveToFile("Sample.xls");
ExcelDocViewer(workbook.FileName);

}
catch (Exception)
{
throw;
}
}
[/csharp]

As you can see we are calling a function CreateChartData to generate the data, so now we will write the function body.

[csharp]
private void CreateChartData(Worksheet sheet)
{
//Country
sheet.Range["A1"].Value = "Country";
sheet.Range["A2"].Value = "Cuba";
sheet.Range["A3"].Value = "Mexico";
sheet.Range["A4"].Value = "France";
sheet.Range["A5"].Value = "German";
//Jun
sheet.Range["B1"].Value = "Jun";
sheet.Range["B2"].NumberValue = 6000;
sheet.Range["B3"].NumberValue = 8000;
sheet.Range["B4"].NumberValue = 9000;
sheet.Range["B5"].NumberValue = 8500;
//Jun
sheet.Range["C1"].Value = "Aug";
sheet.Range["C2"].NumberValue = 3000;
sheet.Range["C3"].NumberValue = 2000;
sheet.Range["C4"].NumberValue = 2300;
sheet.Range["C5"].NumberValue = 4200;
//Style
sheet.Range["A1:C1"].Style.Font.IsBold = true;
sheet.Range["A2:C2"].Style.KnownColor = ExcelColors.LightYellow;
sheet.Range["A3:C3"].Style.KnownColor = ExcelColors.LightGreen1;
sheet.Range["A4:C4"].Style.KnownColor = ExcelColors.LightOrange;
sheet.Range["A5:C5"].Style.KnownColor = ExcelColors.LightTurquoise;
//Border
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].LineStyle = LineStyleType.Thin;
sheet.Range["B2:C5"].Style.NumberFormat = "\"$\"#,##0";
}
[/csharp]

And we will use the preceding function for viewing our chart created.

[csharp]
private void ExcelDocViewer(string fileName)
{
try
{
System.Diagnostics.Process.Start(fileName);
}
catch { }
}
[/csharp]

Now it is time to run our program. You will see the output as follows.

Excel Bar Chart

Excel Bar Chart

As you can see it is very easy to give styles and border to our chart.

[csharp]
//Style
sheet.Range["A1:C1"].Style.Font.IsBold = true;
sheet.Range["A2:C2"].Style.KnownColor = ExcelColors.LightYellow;
sheet.Range["A3:C3"].Style.KnownColor = ExcelColors.LightGreen1;
sheet.Range["A4:C4"].Style.KnownColor = ExcelColors.LightOrange;
sheet.Range["A5:C5"].Style.KnownColor = ExcelColors.LightTurquoise;
//Border
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].LineStyle = LineStyleType.Thin;
sheet.Range["B2:C5"].Style.NumberFormat = "\"$\"#,##0";
[/csharp]

Like this we can crate Line Chart, Radar Chart and many more. Please try those too. Now we will see How to Save Excel Charts as Images.

How to Save Excel Charts as Images

Create another button and write the preceding codes in button click.

[csharp]
private void button2_Click(object sender, EventArgs e)
{
Workbook workbook = new Workbook();
workbook.LoadFromFile("D:\\Sample.xlsx", ExcelVersion.Version2010);
Worksheet sheet = workbook.Worksheets[0];
Image[] imgs = workbook.SaveChartAsImage(sheet);
for (int i = 0; i < imgs.Length; i++)
{
imgs[i].Save(string.Format("img-{0}.png", i), System.Drawing.Imaging.ImageFormat.Png);
}

}
[/csharp]

Here we are taking a file called Sample.xlsx and loop through the charts inside the file and save those as images with few lines codes. Sounds good right?

VB.Net Code
[vb]
Dim workbook As New Workbook()
workbook.LoadFromFile("D:\\Sample.xlsx", ExcelVersion.Version2010)
Dim sheet As Worksheet = workbook.Worksheets(0)
Dim imgs As Image() = workbook.SaveChartAsImage(sheet)
For i As Integer = 0 To imgs.Length – 1
imgs(i).Save(String.Format("img-{0}.png", i), ImageFormat.Png)
Next
[/vb]

Introduction

Hi I hope you all are fine. Today we are going to see a new product Spire.XLS which helps us to create, manipulate, convert EXCEL file to other formats and many more. This product has been introduced by the company E-Iceblue. I hope you have read my article of Spire.Doc. If you have not read it, I recommend you to read it here: Using Spire.Doc

Download source code

Background

Always, managing excel files through code is a tough job for me. If you are also thinking the same, I h3ly recommend this product Spire.XLX from E-Iceblue. It made the task easier than ever. In this article I will show you the demo for converting the Excel files to other formats. I hope you will like it.

Download the files

You can always the needed files from here: Download Spire.XLS

Install Spire.XLS

I am using evaluation version with one month temporary license. There are free versions also available for spire.xls with some limitation. You can try that. Now click on the exe file after you extract the downloaded file. The installation will get started then.

So Shall we start?

Once you Installed, you are ready to go. We will start with a “Simple Windows Form ” Application. Before getting started, Please install Spire.XLs and Visual studio 2008 or above. I am using Visual Studio 2015 RC. I hope everything set ?

Open your Visual Studio, click on New->Project->Select Visual C# (if you are good in C# or select Visual Basic) Project->Windows->Windows forms application->Name your project(I am naming it as Using SpireXLs)

Now create a group box and a button in your form and name them :). Later, click on the button.

Now right click on your project and click add reference, in the browse tab find out the folder in which you have installed spire xls. Usually it will be in the C:\Program Files\e-iceblue\Spire.Xls. Now just find your framework version from BIN folder and add Spire.xls.dll

Now we have added reference too. So shall we start coding ?

Using the code

To start with coding you need to add the needed namespaces as follows.

[csharp]
using Spire.Xls;
using Spire.Pdf;
using Spire.Xls.Converter;
[/csharp]

In the button click event you need to add the following lines codes.

C# Code

[csharp]
private void button1_Click(object sender, EventArgs e)
{
// load Excel file
Workbook workbook = new Workbook();
workbook.LoadFromFile("D:\\MyExcel.xlsx");
// Set PDF template
PdfDocument pdfDocument = new PdfDocument();
pdfDocument.PageSettings.Orientation = PdfPageOrientation.Landscape;
pdfDocument.PageSettings.Width = 970;
pdfDocument.PageSettings.Height = 850;
//Convert Excel to PDF using the template above
PdfConverter pdfConverter = new PdfConverter(workbook);
PdfConverterSettings settings = new PdfConverterSettings();
settings.TemplateDocument = pdfDocument;
pdfDocument = pdfConverter.Convert(settings);
// Save and preview PDF
pdfDocument.SaveToFile("MyPDF.pdf");
System.Diagnostics.Process.Start("MyPDF.pdf");

}
[/csharp]

VB.NET Code

[csharp]
‘load Excel file
Dim workbook As New Workbook()
workbook.LoadFromFile("D:\MyExcel.xlsx")
‘ Set PDF template
Dim pdfDocument As New PdfDocument()
pdfDocument.PageSettings.Orientation = PdfPageOrientation.Landscape
pdfDocument.PageSettings.Width = 970
pdfDocument.PageSettings.Height = 850
‘Convert Excel to PDF using the template above
Dim pdfConverter As New PdfConverter(workbook)
Dim settings As New PdfConverterSettings()
settings.TemplateDocument = pdfDocument
pdfDocument = pdfConverter.Convert(settings)
‘ Save and preview PDF
pdfDocument.SaveToFile("MyPdf.pdf")
System.Diagnostics.Process.Start("MyPdf.pdf")
[/csharp]

In the above lines code, we are loading an excel file MyExcel.xlsx from my drive. The following is the content of our excel file.

Now if you run your project and click our button, you will get a pdf file as follows.

Cool!. Very simple right? Now we will go to other conversions as well.

Excel to HTML

To convert our excel file to HTML, you need to create a button in our form and paste the following codes to the button click event.

C# Code

[csharp]
private void button2_Click(object sender, EventArgs e)
{
//load Excel file
Workbook workbook = new Workbook();
workbook.LoadFromFile("D:\\MyExcel.xlsx");
//convert Excel to HTML
Worksheet sheet = workbook.Worksheets[0];
sheet.SaveToHtml("MyHTML.html");
//Preview HTML
System.Diagnostics.Process.Start("MyHTML.html");

}
[/csharp]

VB.NET Code

[csharp]
Private Shared Sub Main(args As String())
‘load Excel file
Dim workbook As New Workbook()
workbook.LoadFromFile("D:\\MyExcel.xlsx")
‘convert Excel to HTML
Dim sheet As Worksheet = workbook.Worksheets(0)
sheet.SaveToHtml("MyHTML.html")
‘Preview HTML
System.Diagnostics.Process.Start("MyHTML.html")
End Sub
[/csharp]

Now if you run the code, you can see an html file as follows.

Excel To Image

To convert our excel file to image, you need to create a button in our form and paste the following codes to the button click event.

C# Code

[csharp]
private void button3_Click(object sender, EventArgs e)
{
Workbook workbook = new Workbook();
workbook.LoadFromFile("D:\\MyExcel.xlsx");
Worksheet sheet = workbook.Worksheets[0];
sheet.SaveToImage("MyImage.jpg");

}
[/csharp]

VB.NET Code

[csharp]
Shared Sub Main(ByVal args() As String)
Dim workbook As New Workbook()
workbook.LoadFromFile("D:\\MyExcel.xlsx")
Dim sheet As Worksheet = workbook.Worksheets(0)
sheet.SaveToImage("MyImage.jpg")
End Sub
[/csharp]

Now if you run the code, you can see an Image as follows.

Excel to CSV

To convert our excel file to image, you need to create a button in our form and paste the following codes to the button click event.

C# Code

[csharp]
private void button3_Click(object sender, EventArgs e)
{
Workbook workbook = new Workbook();
workbook.LoadFromFile("D:\\MyExcel.xlsx");
Worksheet sheet = workbook.Worksheets[0];
sheet.SaveToFile("MyCSV.csv", ",", Encoding.UTF8);

}
[/csharp]

VB.NET Code

[csharp]
Shared Sub Main(ByVal args() As String)
Dim workbook As New Workbook()
workbook.LoadFromFile("D:\\MyExcel.xlsx")
Dim sheet As Worksheet = workbook.Worksheets(0)
sheet.SaveToFile("MyCSV.csv", ",", Encoding.UTF8)

End Sub
[/csharp]

Now if you run the code, you can see a CSV file as follows.

Please be noted that, you can convert your excel to any other file format, there are plenty of options available. Please try that too. I have given only three options which I use always.

Conclusion

Did I miss anything that you may think which is needed? Could you find this post as useful? I hope you liked this article. Please share me your valuable suggestions and feedback.

Your turn. What do you think?

A blog isn’t a blog without comments, but do try to stay on topic. If you have a question unrelated to this post, you’re better off posting it on C# Corner, Code Project, Stack Overflow, Asp.Net Forum instead of commenting here. Tweet or email me a link to your question there and I’ll definitely try to help if I can.
