A read-only workbook is not automatically an Android storage-permission problem. First distinguish an editing lock from account access, document protection and the particular file you opened. Work on the original issue instead of installing a modified Excel APK.
Record the exact restriction
Write down whether Excel says “locked for editing,” requests a different account, or simply offers viewing. Also record the file’s source: an attachment, a downloaded copy, OneDrive or an organizational location. Two files with the same name may be different copies with different permissions.
Check for an editing lock
Microsoft’s mobile file-lock guide, which applies to Excel for Android, lists another editor, an app instance already holding the file open and a file marked Final among possible reasons. Coordinate with the other editor and close your own unnecessary open instances before trying again.
Do not terminate someone else’s work or remove protection simply to gain access. If you control the file, consult the linked instructions for the relevant cause and application. A restriction set by the owner requires an owner-approved resolution.
Confirm the account and granted rights
For a managed workbook, verify which work or school account is signed in. Microsoft’s Information Rights Management guidance states that Android can open protected files when signed in with an account that has permission. Permission to open a workbook is not a promise of permission to edit, copy or redistribute it.
| Observation | Targeted next check |
|---|---|
| The file is locked for editing | Other editors and your own open instances. |
| A managed file rejects access | The signed-in identity and rights assigned by the owner. |
| A different copy edits normally | Whether you opened an attachment or older downloaded copy. |
| An edit option asks for a plan or account | The exact entitlement message for that app and device. |
Check collaboration conditions separately
Microsoft lists Excel for Android among its co-authoring clients. That does not mean every workbook, storage location and protection setting supports simultaneous editing. Use the supported sharing workflow and confirm the owner granted the intended access.
Protect the original while investigating
- Identify the authoritative file and its owner.
- Record the message and account without exposing confidential content.
- Ask whether another editor currently has it open.
- Request edit rights if your existing access is view-only.
- Save a separate copy only when permitted, and label it clearly.
A separately editable copy is not a repair of the shared original and may not update colleagues’ version. Verify where any change is saved before assuming the issue is resolved.
Will reinstalling Excel fix it?
It does not change the file owner’s permissions or remove a document’s intended restrictions. Avoid deleting local app data while unsynchronized work may remain. If you cannot install the app, that is a separate issue covered by our installation guide.
This is documentation-based troubleshooting, not a test of a specific workbook. Browse the Android guide directory for other app help.
Workbook format and mobile editing entitlement
Microsoft Android format and mobile-app documentation reviewed 21 October 2026.
Before investigating a lock, compare the file extension with Microsoft’s Android file-format table. The table distinguishes opening from editing. A spreadsheet that displays correctly may still be view-only in that format.
| Example format | Documented Android behavior |
|---|---|
| .xlsx | Open and edit supported, subject to access and other conditions |
| .xls, .csv, .ods | Open as read-only; editing not listed as supported |
| .xlsm | Open/edit listed, but VBA functions do not run |
Do not just rename an extension to change a format. When conversion is appropriate, use a supported application to create an authorized copy, then verify the content and saving destination. Mobile support for a file is not desktop feature parity.
Microsoft’s mobile-app guidance says core editing is free on Android screens of 10.1 inches or less, while extra features require a qualifying subscription. Check the actual app, device and signed-in account entitlement before treating an upgrade message as a file-permission error. The reviewed page lists additional Excel capabilities such as PivotTable styling and chart modifications; it does not promise that every desktop feature is available.
Keep the decisions separate: an eligible plan does not grant another owner’s file rights, and edit rights do not make every workbook format editable on Android. Record the exact prompt and confirm both conditions with the appropriate owner or account administrator.
