I will clean and process your messy data in Excel or CSV files, delivering accurate, analysis-ready data.


Services include:

- Remove duplicates and errors

- Fix inconsistent formatting (dates, numbers, text case)

- Split or merge columns

- Standardize values (names, addresses, categories)

- Validate and correct data types


How it works:

1. Send me your file and describe what needs cleaning

2. I process the data with Python and Excel tools

3. You receive clean, structured data back


I handle Excel (.xlsx, .xls), CSV, and Google Sheets exports, up to 50,000 rows.


Message me before ordering with a sample of your data so I can confirm scope.
