Looks like you're the author. I feel this should have its own Show HN post!

Yes I am! Thanks! I have tried that before, it got only a few upvotes!

The Excel-like component DataGridXL did reach the HN homepage, July last year. I plan to release v2 December 2021 :-) Stay tuned!

I just gave this a quick try. I entered "1,2" in the first cell and "3" in the second cell, no quotes. Then I saved, and the raw output looks like this:

    1,2,3,,,,,,,,
    ,,,,,,,,,
    ,,,,,,,,,
    ... (100 lines total)

Most importantly, the comma in "1,2" was not escaped or quoted, so opening the same CSV that I saved produces a different result.

But also, all the extra commas is pretty weird, at least by default. And I don't see any configuration for that anyway.

Thanks for your feedback. The app doesn't have export configuration at this moment, I made this free app as a means to promote/demonstrate the Excel-like component DataGridXL that the app uses.

I have received similar feedback before and I plan to tackle these issues next year, after DGXL2 is released.

Thanks again! Robbert
