How to Fix Access Denied Errors in Power Query for Mac
Question details
The user is experiencing persistent access-denied errors in Power Query for Mac despite verifying that the file paths and read/write permissions are correct.
- Product
- Microsoft Excel
- Device & OS
- Mac
- Scenario
- Trying to run or refresh a Power Query in Excel for Mac to import data.
- Observed behavior
- Excel throws an access-denied error, preventing the query from loading or refreshing the data even when permissions appear correct.
Ensure that the source file is not currently open or locked by another application, and verify that the file is stored in a local directory that Excel has permission to access.
Repair Microsoft Office Using the Setup Assistant
Running the Microsoft Office Setup Assistant can repair broken application files and reset necessary permissions that cause access errors.
Sometimes, the access-denied error in Power Query stems from corrupted Microsoft Office installation files or misconfigured sandbox permissions on Mac. Repairing the installation can restore normal application behavior without deleting your data.
Make sure Excel and all other Microsoft Office applications are completely closed on your Mac.
Open Finder on your Mac and navigate to the Applications folder in the left sidebar.
Locate the Microsoft Office folder, open it, and launch the Microsoft Office Setup Assistant. Follow the on-screen repair prompts to complete the process.
Once the repair is complete, restart Excel, open your spreadsheet, and test the Power Query again.
Use WPS Office for Hassle-Free Data Analysis on Mac
If Microsoft Office continues to throw permission or access-denied errors on your Mac, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for data processing and spreadsheet management without complex permission issues.
Frequently Asked Questions
Why does Power Query say access denied when permissions are correct?
This can happen if the Microsoft Office installation itself has corrupted permission files, or if macOS's built-in sandbox is blocking Excel from accessing specific folders like Desktop or Downloads.
How do I grant Excel Full Disk Access on Mac?
Go to System Settings > Privacy & Security > Full Disk Access, and toggle the switch next to Microsoft Excel to grant it comprehensive access to your files and eliminate permission blocks.
Can a locked source file cause an access denied error?
Yes. If another application or process is actively writing to or locking the source file, Power Query will be unable to access it and will return an access denied error. Ensure the file is closed in other programs.
