You will get I will clean, format and organize your messy data in Excel or CSV
Project details
You will get a clean, consistent, ready-to-use dataset from your messy CSV or Excel file — no more duplicates, mismatched formats, or broken columns.
I use Python to clean data quickly and accurately: removing duplicates, fixing inconsistent casing and whitespace, standardizing dates and numbers into one format, normalizing values (like country names), and flagging or removing invalid rows. You also get a short report showing exactly what changed.
What sets my work apart:
• Fast, accurate cleaning even on large files
• A clear before/after report so you can trust the result
• Consistent, analysis-ready output (CSV, Excel, or your format)
• Optional reusable script so you can clean future files yourself
Send me a sample of your data and tell me what "clean" looks like for you before ordering, and I'll confirm the right package.
