Data cleanup: messy spreadsheets to standardized tablesJigon Yoo
You send spreadsheets or exports that grew messy - duplicates, mixed date and currency formats, inconsistent names, broken headers. You get back one standardized, deduplicated dataset (Excel, CSV or JSON) with every change accounted for.
Nothing is silently deleted or "fixed". Every merge and dedupe runs on explicit matching keys, row counts are reconciled before and after, formats are normalized to one standard - and anything ambiguous is flagged for your review instead of quietly dropped. Every delivery includes a change log that says exactly what was changed and why.
Scope ladder (same as my other channels): $100 - 1 source, up to 5,000 rows. $150 - up to 3 sources merged, up to 20,000 rows. $250 - multi-source cleanup with custom rules and a rerunnable script.
If your data is bigger or messier than the tier you picked, I say so before we start - not after delivery. Public proof of how I work: github.com/jigonyoo.
