Clean Mixed Data in Excel

I have a spreadsheet that blends text fields with numerical columns, and it needs a thorough clean-up inside Excel. The task centers on removing inconsistencies, catching and fixing obvious errors, standardising formats (dates, currencies, capitalisation), eliminating duplicates, and ensuring every column lines up for reliable analysis afterward.

Your final hand-off should be a fully cleaned .xlsx file plus a quick “change log” sheet that summarises the main corrections so I can trace what was adjusted. If you have handled similar mixed-type datasets before, attach or link to a sample so I can gauge the quality of your past work.

No macros or advanced scripting are required—just solid, accurate data cleaning performed directly in Excel and delivered error-free.
