More formatting options on data

You can change the display format of a column but more than that you can use the “Convert data type” action to convert numbers to text in a particular format, like 1’000.00.

Problem : proposed formats are only english, not suitable to other countries. In France for example and other countries we write numbers like “1 000,00” or “1 000.00”, the thousand separator is a white space.

Is it possible to propose other formats or even use the windows formatting settings ?
It can be a new feature I don’t think it’s possible today ?

That’s correct, it’s not possible today. I’ve moved your post to #feature-requests.
