Honestly, saying I'm surprised this wasn't a basic MVP feature for Proton Sheets is putting it mildly... It makes it borderline unusable for anyone not living in the US.

Hello, I'm joining the request for the separators, thank you in advance!

Same for Poland. The space is just something added automatically in programs. But it's absolutely unacceptable for me to not allow using comma as a decimal separator – I'm definitely not switching if this is the case.

I use Iso standard with space as thousand divider, and comma as decimal divider, I was going to do a search and replace, but since it does not exist, I really can't use sheets yet sadly

This idea is the same as: https://protonmail.uservoice.com/forums/945460-general-ideas/suggestions/50852306-decimal-markers
And these 2 should be combined

I totally agree with this option. I have copied/pasted some data from Microsoft Excel to Proton Sheets and it would copy the values wrong because if the difference in usage of decimal separators and thousands separator.
My (language) preference is also that it should be comma for decimal and dot for thousands.

Could you let us know when you plan to enable, in Proton Sheets, the use of the comma as a decimal separator (e.g. 10,50) and the dot as a thousands separator (e.g. 1.000), as an alternative to the English number formatting currently in use?

Additionally, BRL and other Latin-American currencies use commas (`,`) as decimal separators. E.g.:

* BRL (Reais) → R$ 3.144,10

* UYU (Uruguayan Pesos) → $U 3.144,10

* ARS (Argentinan Peso) → $ 3.144,10

As a fellow Brazilian, the lack of support for our currency is the only thing impeding me from using Proton Sheets. :(

Yes, please! Or a custom currency formatting option

Problem:

Currently, user can ony easily set cell to "currency" by clicking on the dollar sign. Which sets currency = $.
If user is european, he can't easily set currency = €
Instead, user needs to click on Format>Number>More Currencies>€ ; which is cumbersome.

Request :

As a user, I want to be able to easily set the format of cells to currency = $ OR € without having to click several times in the toolbars menu, in order for my customer experience to be more fluid and efficient

Yeah, the lack of Polish currency, or generally the support for a custom currency is annoying.

Add support for Polish Złoty (PLN / zł) as currency formatting option.

Currently the localization settings to format numbers or dates seems to be locked into the OS locale or hardcoded to English.

This setting should be customizable per Sheet to allow for different formatting of data.

It would be helpful to set € as standard and use European numerical system as a standard.

Requested feature:
Add a locale or regional setting that allows users to choose their preferred number format. This could be implemented as:

A spreadsheet-level setting (similar to Google Sheets' locale option)
An account-wide preference in Proton settings
Automatic detection based on browser/system locale

Would be nice if you could add the ability changing regional format, mainly for using a comma instead of a dot as decimal seperator ('8.000,00' instead of '8,000.00')

Currently the only option available seems to be the US month/day/year format.

Funnily, enough, pasting a day/month/year date from a google sheet seems to fix this, but I don't wanna live like this!

In Germany, we also use the comma as a decimal separator and the period to separate thousands. Therefore, a “Set Locale” function, as already suggested, would be very useful.

There are already a bunch of requests for "add currency for <country>", so it's clear there is demand for this. It was certainly the first thing I noticed trying to set up a budget spreadsheet.

Sorry, "Locale setting" the correct term.
