How to Fix Excel VBA Runtime Error 52 in OneDrive Files
Question details
The user needs to resolve an error preventing a VBA macro from successfully running and generating a CSV file when the workbook is saved in a OneDrive-synced location.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Executing a VBA macro that uses an Open statement to build a file path from the workbook's parent path and name, while the workbook resides in a OneDrive-synchronized folder.
- Observed behavior
- Excel throws Runtime Error 52 ('Bad file name or number') because the VBA code receives a OneDrive web URL instead of a standard local directory path, making the file path incompatible with the Open statement.
Before modifying your VBA code, ensure that your OneDrive application is fully synced on your computer and create a backup copy of your Excel workbook to prevent accidental data loss.
Update the VBA Code to Use the Local OneDrive Path
Modify the VBA macro to dynamically convert the OneDrive URL into a valid local file path before executing the Open statement.
VBA's native file operations do not recognize the 'https://' paths generated by OneDrive AutoSave. By replacing the cloud URL with your local user environment path, the macro can run correctly.
Press the 'Alt + F11' shortcut keys in Excel to open the Visual Basic for Applications (VBA) editor.
In the Project Explorer, double-click the module containing your macro and find the specific 'Open' statement that is triggering Runtime Error 52.
Update the path variable in your code. Replace the generic 'ActiveWorkbook.Path' logic with code that utilizes 'Environ("OneDrive")' or 'Environ("USERPROFILE")' to point to the local synchronization folder instead of the cloud URL.
Save your changes in the VBA editor, return to your Excel worksheet, and run the macro again to verify that the CSV file is generated successfully.
Run the Macro Outside the OneDrive Folder
Temporarily relocate the workbook to a non-synchronized local folder to bypass OneDrive's path formatting entirely.

Frequently Asked Questions
What does Runtime Error 52 mean in Excel VBA?
Runtime Error 52 translates to 'Bad file name or number.' It indicates that the VBA macro is trying to access a file or directory that doesn't exist, is locked by another process, or uses an invalid path string format that the system cannot parse.
Why does OneDrive change my VBA file paths?
When AutoSave is enabled for OneDrive files, Microsoft Excel treats the workbook's file path as a web URL (e.g., starting with https://d.docs.live.net) rather than a standard local file path (e.g., C:\Users\). VBA's native file handling functions do not support these web URLs.
Can I permanently disable the OneDrive URL path format in Excel?
You cannot completely disable this behavior for cloud-synced files without turning off AutoSave or unlinking OneDrive. The best practice is to handle the path conversion dynamically within your VBA code using functions like Environ("OneDrive").
