Excel Data Cleaning Specialist

I have several Excel spreadsheets that need careful data cleaning before I can use them in my reporting workflow. The priority is to correct formatting issues—cell styles, dates, numbers, and text should all follow a single, consistent standard so the files import smoothly into my dashboards.

Here is what I will provide:
• The original Excel workbooks, each with multiple sheets.
• Notes on the preferred date, number, and text formats.

What I need back:
1. Cleaned versions of each workbook with all formatting inconsistencies resolved.
2. A brief change log (one sheet is fine) that lists the main fixes you made so I can trace edits later.

If you spot duplicates or other obvious errors while you work, flag them; I may open a follow-up task for deeper cleanup once the formatting is stable.

Strong Excel skills—formulas, Find & Replace, Power Query, or VBA where helpful—will make this go quickly. Please let me know your estimated turnaround time and any clarifying questions when you submit your bid.
