Does https://editcsvonline.com count? It's an Excel-like CSV-editor that does not require an account. It's made with localstorage and a save button :-)
The Excel-like component DataGridXL did reach the HN homepage, July last year. I plan to release v2 December 2021 :-) Stay tuned!
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.
I have received similar feedback before and I plan to tackle these issues next year, after DGXL2 is released.
Thanks again! Robbert
