Click File > Save As, and select the location where you want to save the file. , point to the arrow next to Save As, and then click Other Formats. In the File name box, type a name for the XML data file. In the Save as type list, click XML Data, and click Save.
Javascript Excel - Import Data From ExcelThe Excel file is read into Uint8Array object, which is then passed to the load method exposed by the Excel library. Once the worksheet is loaded into the Excel library object, we can read each cell value and build a JSON array that will be used as the igGrid data source.
You could generate a data URI, and let the user save the link. However, IE8 has very limited support for data URIs. There is a 32 KB limit, and it's not allowed to be used with a href.
Also, you still need to find a actual XLSX JS library... But it is possible.
