Excel Data Entry & Cleanup

I need support with a sizeable Excel file that must be reorganised, cleaned and formatted according to the templates I will supply. Your task is to follow those guidelines precisely, arrange the data into the correct column order, remove inconsistencies, standardise dates and numbers, and consolidate multiple sheets into one well-structured master workbook. Accuracy is critical—every cell has to comply with the rules before the project is considered complete—and I expect a quick yet careful turnaround.

Deliverables:
• Updated, fully formatted Excel workbook in .xlsx
• Brief changelog outlining any issues spotted and fixed

Let me know your estimated completion time and any questions you may have so we can begin.
