Dear Ashwyn Assy,
Thank you for contacting Microsoft Q&A Forum and bringing this matter to our attention regarding the incorrect currency format displayed in SharePoint Online when using the locale "English (South Africa)."
I understand how frustrating this limitation can be, especially when precision in currency formatting is crucial for your work. However, at the moment, SharePoint Online:
- Does not allow customization of the decimal format inside a Currency column.
- And it inherits the number and currency format directly from the site’s Regional Settings, which are based on the underlying locale (Culture Info).
Unfortunately, changing the Regional Settings at the site level can affect several other aspects of your site, such as:
- Date and time formats
- Number separators
- Calculated columns and formulas
Due to these impacts, I do not recommend changing the Regional Settings as a workaround in this case.
