I'd love to have a way to make xlsx files be git-compatible, i.e. stored in plaintext.

I realise this may be out-of-scope as it's kind of baked into the file format, but does Nobie offer any functionality in that direction?

via the CLI, you could probz stream values and formatting out of the sheet, although we probably need to add a few things to ensure you can reach into every nook and cranny of the xlsx file.

We an example on our site of how you might use git & nobie together.
