webix.toExcel File Size Is Large.

Hi,
When we use webix.toExcel the .xlsx file size is large. If we open the same file and do “Save As” the file size reduces almost 90%. Is there any technique or any property to compress the file size.

Hello @Ranjith_G,

When we use webix.toExcel the .xlsx file size is large. If we open the same file and do “Save As” the file size reduces almost 90%. Is there any technique or any property to compress the file size.

Unfortunately, there is no way to reduce the file size from our side. Exporting is being handled by a 3rd party library - SheetJS. As can be seen in the relevant issues thread:

For performance and compatibility reasons, the default options sacrifice file size

Meaning the file size is purposefully made larger for the reasons stated above (e.g. trying to cut down in size would result in export taking longer overall, as well as potential issues while trying to open the resulting file).
