Progress Indicator (Vue)

The sample demonstrates how to export FlexGrid content to XLSX files asynchronously, display a progress indicator and cancel the export.

The onProgress argument of the FlexGridXlsxConverter's saveAsync method is used to track the progress of converting and exporting your data into Excel's .xlsx file format, and the cancelAsync method is used to cancel the export.
