Hello,

Currently I am reviewing your library to see whether or not I can use it instead of my own implementation.

For now, I found the only issue with performance:

• 6-7s with our implementation, click the 'Click me to start DataGrid ExcelExport and wait 5-10 secs (there is no visual progress)' button to export [20000 x 50] array
• 15-20s with ExcelJS, click the 'Click me to start ExcelExport and wait 15-20 secs (there is no visual progress)' button to export [20000 x 50] array

Click the [Click me..] button on each page and review the elapsed time in the shown alert dialog.

Do you have plans to improve it? There are no notes about performance in the Backlog
