I have a set of mailing addresses sitting in Excel and CSV sheets that needs one straightforward touch: remove every duplicate entry so I’m left with a single, clean master list. No re-formatting or data enrichment is required—just precise de-duplication with minimal manual typing. You’ll receive the raw files, run your preferred de-dupe method in Excel, Google Sheets, Python, Power Query, or any other reliable tool, and then return: • a cleaned file containing only unique mailing addresses • a short log or summary noting how many duplicates were found and removed I’ll spot-check against the original to confirm all duplicates are gone and nothing else was altered. If that sounds clear, let’s get started.
