@Hirenp75 Can you share the code that you are using to upload and parse xlsx file? I have used sheetjs with worker process to parse really big excel file and never had to wait that longer.

Is there any thing new about it?
To avoid the blocking I did the XLSX reading operation in a separate worker "other thread" so nothing blocks the main tread.
But now it takes around ~4 minutes to read a ~18MB file.
And crashes with ~100MB files

We need a solutions please?
Any other libraries? Even if paid, just a good one with large data sets

@sombek can you please share your code block or guide on how you implemented web worker for xlsx reading, because i'm getting error "Uncaught (in promise): ErrorEvent: {"isTrusted":true}".
Please help asap.
