This topic explains how to export or import FlexGrid content to/from an Excel xlsx file. To export the FlexGrid content in Excel format, pass the FlexGrid instance to the FlexGridXlsxConverter.save method. This generates xlsx file content, which can be saved to local file or sent to a server. To import an Excel (xlsx file) content to your FlexGrid control, pass the FlexGrid instance and the xlsx file content to the FlexGridXlsxConverter.load method. The example uses Sale.cs model, which was added to the application in the QuickStart.
The following code examples demonstrate how to export or import FlexGrid content to/from an Excel xlsx file:
Before implementing the code below, you need to add the jszip.min.js library reference to import and export FlexGrid to/from an Excel xlsx file.
