I will clean and format your messy excel or CSV data files

If a messy spreadsheet is slowing you down, send it over and you get back a clean one.

Duplicate rows, inconsistent text (NORTH, north, and North treated as three different things), stray whitespace, missing values, columns that don't line up. I clean all of it in Python and send back a ready-to-use Excel or CSV file.

What I fix:

- Duplicate rows removed

- Text normalized so the same value stops splitting into variants

- Whitespace and casing cleaned up

- Missing values handled the way you choose, filled or flagged

- Columns made consistent

You also get a short note of exactly what was changed, so nothing is altered without you knowing. The Premium package turns that note into a full data-quality report: missing values per column, duplicate count, and detected column types on their own sheet.

Encodings are not a problem either. Polish and Cyrillic CSVs, semicolon delimiters, decimal commas, all handled.

If your file is more tangled than most, or it holds sensitive data, message me first and I'll look at it before you order.
