This article will get you started in using the RadSpreadProcessing library.

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

You can find the required references in the SpreadProcessing NuGet packages section.

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

csharp

	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

csharp

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

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

csharp

	string fileName = "SampleFile.xlsx";
	
	XlsxFormatProvider 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.
