About this Gig

Got messy spreadsheets, duplicate rows, or multiple files that need to be combined? I'll clean your CSV or Excel files with Python and deliver a ready-to-use dataset.


What I fix:

- Duplicate rows removed

- Column names standardized (snake_case)

- Data types auto-detected (numbers, dates)

- Encoding issues fixed (accents, special characters)

- Empty rows and columns removed

- Merge multiple files into one clean dataset


What you send me: your CSV or Excel file(s)

What you get back: a clean file + a summary of every change made
