Known file getting tagged as malicious

Question

I have a single macros enabled excel file, every time I make changes and save it with different name Defender MDE flags it as malicious and file gets corrupted. Every time I make changes, SHA value changes and hence submitting it to Microsoft as clean file is not helping. How do I stop this from getting corrupted? Is there a way I can whitelist any file by its name?

Hi @Aishwarya RM

Thank you for posting Microsoft Q&A Forum!

If you have a file that was either wrongly detected as malicious or was missed, you can Submit a file for analysis.
If you determine that the macros are safe, you can add your file to the Microsoft Defender for Endpoint exclusions list. This will prevent the file from being scanned and flagged as malicious in the future.
The other side kindly check your Macros and protect against macro malware.
