Excel Data Cleaning & Deduplication

I have an Excel file that needs a thorough spring-clean. The goal is to deliver a fresh workbook with every duplicate row removed, obvious spelling mistakes fixed, and formatting brought back to a consistent, readable style. No formulas need to be touched or rebuilt—this task is strictly about tidying the existing data.

Please work directly in Excel (any recent version is fine), use the built-in duplicate-finder or your preferred Power Query method, and run a quick spell-check to catch the visible errors. When the clean-up is complete, send back the updated file along with a brief note summarising what you changed (e.g., “120 duplicates deleted, 34 spelling corrections made”).

That’s it—simple, focused, and ready to go.
