Thanks for your comment!

It will handle 100,000s of cells without much issues: it has virtualized scrolling and rendering .

I have not tested it with large file sizes, like your 20mb or 50mb examples.

I would love to test the product with it. Is there a way you could send us an example of such a workbook, where data is anonimized?

You can send it to [e-mail]

Robert I've forwarded a xlsx file for you to test on the email you've mentioned!

For sure!

You can test any edge-cases.

I'll send it over at the email you've shared!
