I will clean, deduplicate and format your excel or CSV data

I clean and tidy Excel and CSV data so it is ready to use. My experience comes from personal portfolio projects in data cleaning and validation with Python and pandas. I have no paid Fiverr orders yet, so please message me first with a small anonymized sample and your rules.

What I do, using rules we agree before I start:

Remove duplicate rows (all columns or the key columns you choose).

Handle blank cells: flag, fill by your rule, or remove.

Fix inconsistent text, dates, phone numbers and number formats.

Return a cleaned file plus a list of rows I could not fix safely.

I keep your original file untouched and never guess ambiguous values. Higher packages add an exceptions report and a before/after summary.

Not included: web scraping, dashboards, macros, complex formulas, scanned or handwritten documents, or importing into other platforms.

Please send one sheet per file (Excel or CSV). Do not send passwords or highly sensitive personal data.
