Hide columns in multiple workbooks without opening excel files

[abulo0416]

Hi all,
I have about 100 clients' excel report files,and I need to hide specific columns in multiple excel files if any cell in the columns match "AAA" or "BBB" or "CCC".
I am looking to see if there's a way to quickly hide the columns if the above conditions are met, to all 100 excel files without open multiple excel files.

Any help is appreciated. Thank you very much.
