Parse data after edit/paste

[benediktvaldez]

Is there a way to provide a custom function to parse pasted data? Similar to parsePaste in react-datasheet

Is there a way to provide a custom function to parse edited data? As in, when the user is done editing and exits edit mode, I'd like to validate the value and possibly autoformat it for example.

I'd actually love to be able to set a “valid/invalid” state per cell (I'm doing it now via custom DataViewer which is fine I guess)

Great idea, I'm pretty busy right now to implement it myself but PRs are welcome
