Quick $10 Customer Data Cleanup

I have a small batch of customer records that need a fast once-over so they are ready for import into our CRM. The dataset is already in spreadsheet format; what it lacks is consistency. I need you to spot and remove duplicates, standardise name capitalisation, tidy address, phone, and email fields, and flag anything that looks obviously inaccurate. No new research is required—this is purely a cleanup task.

Deliverable: the same sheet returned in .xlsx with a brief “change log” tab outlining what you fixed (e.g., duplicate rows removed, fields corrected).

A good eye for detail and solid spreadsheet skills (Excel or Google Sheets) are all that’s necessary. If you can turn it around quickly and accurately, the $10 is yours, and there will likely be more batches to follow.
