As outlined in the linked support article there are already quite a few localizations in place:
But I think a few more settings would make this pretty much perfect.
- Choose symbol for the 1000-separator. E.g. comma or space.
- Choose period or comma for decimals (although I realize this probably messes up the whole formula language with dot-operators…)
For currencies, same as above, but also:
- Choose if the symbol is before or after the number.
- Choose if there is a space between the symbol and the number.
As an example of what I (egotistically) want to achieve is the formatting for Swedish Crowns. What I can achieve with the available settings is “kr8,740.85” while the standard localization for Sweden is “8 740,84 kr”.
