You can save data to an excel file using one of the SaveExcel methods of the FpSpread class. This method accepts the path and file name for the file to save, and any additional parameters depending on the particular method.

One of the parameters used in the SaveExcel method is the ExcelSaveFlags enumeration. It provides the following formats to save data in Excel.

• Excel Workbook Format (.xlsx files)
• Excel 97-2003 BIFF8 Format (.xls files)

To save data to Excel Workbook format, use the UseOOXMLFormat option. If you want to save the spreadsheet data along with all the spreadsheet settings to an Excel file, you need to use the Exchangeable option as well. This option helps to retain all the data even after exporting and importing (with the ExcelOpenFlags Exchangeable option) the Excel file in Spread.NET. By default when you save to Excel, whatever is stored in the data model of the Spread is written out to a file or stream in BIFF8 format.

It is also possible to store cell data from a single worksheet into an excel file using the SaveAs method of ISheet interface. This method allows you to specify the path and file name for the file to save, along with any additional parameters that may be necessary based on the method's requirements.

Refer to the following sample code that saves the cell data from a worksheet to an excel file.

// Export worksheet to excel with options
IWorksheet TestActiveSheet = fpSpread1.AsWorkbook().ActiveSheet;
TestActiveSheet.SaveAs("WorksheetToExcel.xlsx", GrapeCity.Spreadsheet.IO.FileFormat.OpenXMLWorkbook, options: ExportOptions.RowHeader);

' Export worksheet to excel with options
IWorksheet TestActiveSheet = FpSpread1.AsWorkbook().ActiveSheet
TestActiveSheet.SaveAs("WorksheetToExcel.xlsx", GrapeCity.Spreadsheet.IO.FileFormat.OpenXMLWorkbook, options:=ExportOptions.RowHeader)

Export Image Cell Type to Excel

If you are saving a spreadsheet in an Excel file and it contains an image in an image cell type, the following behavior can be observed:

• If you specify the Exchangeable option, the image cell type will be saved to XLSX file.
  • If you open the exported file in Excel, an empty cell is displayed.
  • If you open the exported file in Spread without Exchangeable option, an empty cell is displayed
  • If you open the exported file in Spread with Exchangeable option, the image cell type cell is displayed.
• If you do not specify the Exchangeable option, the image cell type won't be saved to XLSX file and Spread will export a shape instead.
  • If you open the exported file in Excel or Spread (with or without Exchangeable option), an empty cell and a shape are displayed.

Example

The following example saves the spread data along with all the settings to an Excel file using the SaveExcel method which has ExcelSaveFlags options UseOOXMLFormat and Exchangeable as arguments.

// Save spread data to an Excel file (.xlsx).
fpSpread1.SaveExcel("C:\\excelfile.xlsx", FarPoint.Excel.ExcelSaveFlags.UseOOXMLFormat | FarPoint.Excel.ExcelSaveFlags.Exchangeable);

' Save spread data to an Excel file (.xlsx).
FpSpread1.SaveExcel("C:\\excelfile.xlsx", FarPoint.Excel.ExcelSaveFlags.UseOOXMLFormat | FarPoint.Excel.ExcelSaveFlags.Exchangeable)

Using the Spread Designer

1. From the File menu, choose Save.  
   The Save As dialog appears.
2. Change the Save as type box to Excel files (*.xls).
3. Specify the path and file name to which to save the file.
4. Select Exchangeable option and UseOOXMLFormat option from Select Excel Save Flags drop-down list, and then click Save.
   If the file is saved successfully, a message appears stating the file has been saved.
5. Click OK to close the Spread Designer.

Example

This example code saves the data in a Spread component to an Excel-formatted file and specifies that both row and column headers are included in the output.

// Save the data to an Excel-formatted file, including headers.
fpSpread1.SaveExcel("C:\\excelfile.xls", FarPoint.Win.Spread.Model.IncludeHeaders.BothCustomOnly);

' Save the data to an Excel-formatted file, including headers.
FpSpread1.SaveExcel("C:\excelfile.xls", FarPoint.Win.Spread.Model.IncludeHeaders.BothCustomOnly)

Document Caching

The DocumentCaching option in the ExcelOpenFlags or ExcelSaveFlags enumeration allows you to open, edit, and save without the loss of advanced document content and formatting. The content can be lossless only if the opening file format is similar to the saving file format. If the advanced document content uses files besides the xls(x) file, then the additional files need to be in the same folder with the xls(x) file. Advanced content could be macros, ActiveX controls, data connections, and so on.
