How to Fix Power Query Excel Data Source and Component Loading Errors
Question details
Users are encountering component-loading and data-source query errors when importing data using Power Query.
- Product
- Microsoft Excel (Office LTSC 2024)
- Device & OS
- not provided
- Scenario
- Importing data from local or external Excel workbooks into Power Query, even when starting from a completely blank workbook.
- Observed behavior
- Power Query fails to load components and throws data-source query errors, blocking the data import process.
Verify whether your Office installation is 32-bit or 64-bit, and ensure your computer is connected to the internet to download the latest software updates.
Install Office Updates and Verify Bitness
Updating Office and ensuring you are running the recommended 64-bit version can resolve underlying compatibility and memory-related Power Query failures.
Many component loading errors stem from outdated Office builds or memory limitations in the 32-bit version of Excel. Testing a clean environment ensures the issue is isolated to the application rather than the file.
Open Excel, create a new blank workbook, and attempt to run the Power Query import again. If it fails here, the issue is with the application components, not file corruption.
Navigate to File > Account > Update Options and select 'Update Now'. Allow Excel to download and install the latest patches.
Go to File > Account > About Excel. If you are running the 32-bit version and frequently process large datasets, consider uninstalling it and installing the 64-bit version to prevent component crashes.
Investigate LTSC 2024 Compatibility Issues
Determine if the error is specific to Office LTSC 2024's handling of Excel connectors and take appropriate diagnostic steps.

Frequently Asked Questions
Why does Power Query fail to load even in a new blank workbook?
If Power Query fails in a blank workbook, the problem lies within the Excel installation itself. This is typically caused by corrupted software components, missing updates, or a known compatibility bug within specific versions like Office LTSC 2024.
Will switching to 64-bit Office fix my Power Query errors?
Yes, it often helps. Power Query is resource-intensive, and the 32-bit version of Office can quickly run out of memory, leading to component-loading errors. The 64-bit version provides much better stability for data processing.
Should I manually re-register Power Query DLL components?
You should only re-register DLL files if directed by official Microsoft support documentation. Modifying DLL registrations manually without proper guidance can cause irreversible damage to your Office installation.
