is there a limitation on the amount of data that can be exported using spreadSheet.saveAsExcel() ? I have a spreadsheet with 100 columns and 3500 rows. When I run this method the browser crashes? I am using Chrome Version 56.0.2924.87 (64-bit).
The spreadsheet's data is exported in-memory. The maximum size of exported file depends on the browser and the system itself. I suggest that you check server-side solution as Telerik Document Processing Library: http://docs.telerik.com/devtools/wpf/controls/radspreadprocessing/overview.
