Hello Hari,
Welcome to Microsoft Community.
I understand you would like to unblock the Macro in excel running. My Sincerest appologies for the troubles and inconveniences this have caused
A macro is a series of commands used to automate a repeated task and can be run when you have to perform the task. However, some macros can pose a security risk by introducing viruses or malicious software to your computer. Never enable macros in a Microsoft 365 file unless you're sure you know what those macros do and you want the functionality they provide. You don't need to enable macros to view or edit the file. Kindly Go through the link provided to get more information on Macros Enable or disable macros in Microsoft 365 files - Microsoft Support
