Excel Data Cleaning & Formatting

I have a batch of Excel spreadsheets that need attention. The files contain mixed-quality data collected from different sources, and I want them professionally cleaned and organised so I can run reliable reports without spending hours hunting for errors.

Here’s what I need from you:
• Identify and remove duplicate rows so each record is unique.
• Re-organise the data into consistent, clearly labelled columns (some sheets will require inserting or merging columns to match a master layout).
• Apply the necessary formulas where helpful—for example, automated totals or validation checks—to keep the sheets error-resistant.

Every spreadsheet you return should be tidy, consistently formatted (fonts, cell styles, date/number formats), and ready for immediate analysis. If you spot anomalies or suspect data gaps, flag them so I can decide whether to amend or discard those records. I will supply the raw Excel files and a brief style guide; you deliver the cleaned versions plus a short change log summarising the fixes applied.

Accuracy and attention to detail are more important than speed, but once you’re familiar with the structure I’d like a quick turnaround. If this goes smoothly there will be ongoing sheets each month that need the same treatment.
