I can't access Excel. What could be the reason?

Hi Saran Hapanna,

Hope your day's fine. Im Jhun an independent adviser. Sorry to hear about your issue in opening MS Excel. Let's try these some steps to make it work again.

First try to repair your office > Open your Programs and features or press Windows+R, type on run bar "appwiz.cpl". Scroll down to "Microsoft Office" app > Right-Click and choose "Change" > "Quick Repair". If this doesnt work, repeat everything, but next time choose "Online Repair" and wait for a few minutes. Then try opening your Excel again.
Second, try to update your App. Try to open any MS Office app if you cant open your Excel. Go to "File" > "Account" > "Update Options" > Update Now

Third, try to sign out and sign in again in your Microsoft Account linked to your Office license. Open and Office App, click "File">Account> Sign-out and Sign-in again.

Last, try to check if your MS Office license is active. Go to Microsoft account website and Sign-in your MS Account linked with your MS Office license. Check if your Microsoft 365 / Microsoft Office shows active. If it is expired, this may be the reason why you cant open your MS Office.

Hope some of the steps above would work on your problem.

Regards,

Jhun
