Hi Paul,
You can change the direction of Excel to left-to-right with steps below:
- Click File > Options > Advanced > Display, select Left-to-right for Default direction.
- Uncheck the Show sheet right-to-left option under Display options for this worksheet.
About the Arabic “Sheet1” tab, please confirm if you have ever used Arabic as the display through File > Options > Language > Choose Display Language.
If so, try changing it to Arabic, and then back to English again.
Meanwhile, please provide the screenshot of the Product information of your Office application (Click File > Account > Product Information) and the Chose Display Language setting page.
Regards,
Jiaxing
