Excel Duplicate Removal Project

I require assistance with cleaning up my Excel files. I have three Excel files, and I need duplicates in one specific column of the first file removed from all 2 files. The structure of all files is the same, with identical columns.

Ideal skills for this project include:
- Proficient with Excel
- Attention to detail
- Experience with data cleaning

Please be prepared to delete identified duplicates from all files.
