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.

The following example creates a workbook and adds a worksheet to it.

Example 1: Create a workbook and add a worksheet

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

You can then create a CellSelection and set a value for the selected cells. The following example creates a cell and assigns a string value to it.

Example 2: Create a cell and set a string value

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. The following example exports the previously created workbook to .xlsx format.

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

Example 3: Export a workbook to XLSX

string fileName = "SampleFile.xlsx";

XlsxFormatProvider formatProvider = new XlsxFormatProvider();

using (Stream output = new FileStream(fileName, FileMode.Create))
{
	formatProvider.Export(workbook, output, TimeSpan.FromSeconds(10));
}

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

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