Why won't my 365 CoPilot on my phone let me just edit and add data to my Excel Spreadsheet

For years, I've tracked auto expenses using Excel entering gallons of gas, the date, price, do an autofill as raw data that is analyzed by a couple of Pivot Tables. Today it wouldn't let me just enter data - it wanted to "Tell it what I wanted it to do." "Kiss my ass" was apparently not what it was looking for. Can I just get back to Excel and leave the VooDoo stuff to people who are better at dealing with lost capabilities without explanation?

    Hi @Bob Larson 

    Thank you for reaching out to the Microsoft Q&A forum 

    I understand how frustrating and inconvenient it can be when the Excel app has worked consistently for many years but suddenly starts showing unexpected behavior that prevents you from editing. 

    Based on your question, may I clarify whether the behavior you mentioned occurs when you open Excel through Microsoft 365 Copilot, or when you open it using the standalone Excel Android app?

    In my testing environment, I’m still able to open and edit files normally in the Excel Android app. To better understand what you’re experiencing, could you please share a screenshot of the behavior through the private message? 

    Please check your inbox for an email with the subject “New private message on Microsoft Q&A question” to review my response. 

    In the meantime, you can try the steps below, which often help resolve unexpected behavior in the Excel Android app: 

    • Verify whether the sheet is opening in “Read‑only” mode. 
    • Clear the app cache by holding the Excel icon, selecting App Info, then Storage Usage, and choosing Clear Cache. 
    1. undefined
    2. User's image
    3. User's image
    • Sign out of the affected account and sign back in. 
    • If the issue continues, you may consider reinstalling the Excel app. 

    If I have misunderstood any part of your situation, or if you have any updates or further questions, please feel free to reply. I appreciate your time, and I look forward to hearing from you soon.

    It seems that your issue with the Microsoft 365 CoPilot in Excel on your phone may be related to the functionality changes or settings within the app. Sometimes, features like CoPilot can interfere with standard editing capabilities, prompting users to utilize AI suggestions instead of allowing direct data entry.

    Here are a few steps you might consider to troubleshoot the issue:

    1. Check for Updates: Ensure that your Excel app is updated to the latest version, as updates can fix bugs and improve functionality.
    2. Restart the App: Close the Excel app completely and then reopen it to see if the issue persists.
    3. Reinstall the App: If the problem continues, uninstalling and reinstalling the app may resolve any underlying issues.
    4. Settings Review: Look into the app settings to see if there are options related to CoPilot or data entry that can be adjusted.

    If these steps do not resolve the issue, you may want to reach out to Microsoft support for more specific assistance regarding the CoPilot functionality.
