Clean Duplicates in Excel Sheets

I have up to two Excel workbooks that need a quick but thorough duplicate-removal pass. The structure of each file should stay exactly as it is—same column order, formulas, and formatting—only the repeated rows must go. Once the duplicates are gone, simply return the cleaned versions in XLSX format so I can drop them straight back into our workflow.

You may use the duplicate-filter built into Excel, a VBA macro, Python (pandas), or any other method you prefer, as long as the final files open flawlessly in the latest desktop version of Microsoft Excel and every unique record is preserved. Please let me know how soon you can turn this around and, if helpful, describe the approach you plan to take so I have confidence in the accuracy of the result.
