Hi @Felipe_Villa 


What version of Excel you use?



Hi @Jihad Al-Jarady 


it's Excel 365 on the cloud. I'm not using desk app excel.

Hi @Felipe_Villa 


Try to use the shortcut ALT + T + O


Search for "Options" in the search box on the main screen top tab


Excel Online takes regional setting of your OneDrive (or SharePoint site), you need to change them.
