Solution 1Recommended

Run Excel in Safe Mode and Disable COM Add-ins

Booting Excel in Safe Mode bypasses third-party add-ins, which are common culprits for causing Power Query to freeze or fail to load.

Third-party COM add-ins can sometimes interfere with Excel's background processes, preventing the Power Query Editor from rendering correctly.

1
Launch Safe Mode

Press the Windows key + R to open the Run dialog. Type 'excel /safe' and press Enter to launch Excel in Safe Mode.

2
Test Power Query

Open a blank workbook and attempt to launch the Power Query Editor. If it opens successfully, the issue is likely caused by an add-in.

3
Manage Add-ins

Go to File > Options > Add-ins. At the bottom of the window, select 'COM Add-ins' from the Manage drop-down menu and click 'Go'.

4
Disable and Isolate

Uncheck all add-ins in the list and click OK. Restart Excel normally and enable the add-ins one by one to identify which one is causing the conflict.

Run Excel in Safe Mode and Disable COM Add-ins
Isolating the Conflict: If the issue persists in Safe Mode, the problem is not related to add-ins. You should proceed with repairing your Microsoft 365 installation.

Frequently Asked Questions

Why does Excel freeze when I click 'Get Data'?

This usually happens due to corrupted cache files, conflicting third-party COM add-ins, or an outdated Microsoft 365 version. Running Excel in Safe Mode can quickly help you determine if an add-in is the cause.

How do I clear the Power Query cache manually?

Go to the Data tab in Excel, click on 'Get Data', and select 'Query Options'. Under the Global section, choose 'Data Load', and click the 'Clear Cache' button to remove temporary files.

Will reinstalling Excel fix the Power Query Editor issue?

Yes, performing an Online Repair or fully reinstalling Microsoft 365 often resolves deep-seated corruption issues or missing files that prevent Power Query from launching properly.

What details should I record before contacting Microsoft Support?

You should note down your exact Excel version, Windows operating system version, the steps you take before the freeze occurs, and whether the issue happens in all workbooks or just a specific one.
