Getting Started

This article will get you started in using the RadSpreadProcessing library. It contains the following sections:

• Package References

• Creating a Workbook

• Exporting

• Using RadSpreadsheet

If you still don't have Telerik Document Processing installed, check the First Steps topic to learn how you can obtain the packages through the different suites.

Package References

The libraries support .NET 8, .NET 9 and .NET 10. .NET Standard-compatible packages are available as well. The packages for .NET Standard don't include 'Windows' in their names. (e.g. Telerik.Documents.Core). For more information check Cross-Platform Support article.

In order to use the model of the RadSpreadProcessing library in your project, you need to add references to the following packages:

Needed when exporting to PDF format a document containing images different than Jpeg and Jpeg2000 or ImageQuality different than High. The Telerik.Documents.ImageUtils package depends on SkiaSharp. In order to use this package, you will need to add а reference to SkiaSharp. With the R2 2023 changes SkiaSharp replaced ImageSharp as the required dependency.

Creating a Workbook

The document model allows you to instantiate a new workbook and populate it with any data you want.

Example 1 shows how you can create a workbook and add a new worksheet to it.

Example 1: Create Workbook

Workbook workbook = new Workbook(); 
Worksheet worksheet = workbook.Worksheets.Add(); 

You can then create a CellSelection and set any value to the selected cells. Example 2 shows how you can create a cell and set a string value to it.

Example 2: Set value of cell

CellSelection selection = worksheet.Cells[1, 1]; //B2 cell 
selection.SetValue("Hello RadSpreadProcessing"); 

Exporting

The RadSpreadProcessing library supports a variety of formats to which you can export the contents of a workbook using FormatProviders. Example 3 shows how you can export the previously created workbook to .xlsx format.

For more examples and application scenarios of Importing and Exporting a Workbook to various formats check out the Import/Load and Export/Save RadSpreadProcessing Workbook knowledge base article.

Example 3: Export to Xlsx

string fileName = "SampleFile.xlsx"; 
 
IWorkbookFormatProvider formatProvider = new XlsxFormatProvider(); 
 
using (Stream output = new FileStream(fileName, FileMode.Create)) 
{ 
    formatProvider.Export(workbook, output); 
} 

More information about the import and export functionalities of RadSpreadProcessing is available in the Formats and Conversion section.

For more complete examples head to the Developer Focused Examples section of the library.
