Feature Request: Regional Number Format Should Respect Thousand Separator Automatically

In ONLYOFFICE Spreadsheet Editor, even when the regional settings are correctly configured (e.g., Spain or Germany), and the thousand separator is explicitly set to a dot (.) in the Advanced Settings, the default “Number” format does not automatically apply the thousand separator.

The only way to enable it is to manually go to More Formats → Number → check “Use thousand separator”, which is inefficient when working with large datasets or templates that rely on consistent formatting.

I suggest the following improvements:

  • The default “Number” format should automatically respect the regional settings, including the thousand and decimal separators.
  • If the user sets a custom separator in Advanced Settings, it should be reflected immediately in the default number formatting.
  • Optionally, allow users to define and save a preferred number format (with thousand separator) as the default for new spreadsheets.

This would greatly improve usability and align ONLYOFFICE with the behavior of other major spreadsheet editors.
