About this gig
Got messy data full of duplicates, inconsistent formatting, or missing values? I'll clean it up and deliver a precise, analysis-ready file you can trust.
What I handle:
- Remove duplicates and fix inconsistent data entry
- Standardize formats: dates, phone numbers, addresses, currency
- Split/merge columns, rename headers, restructure tables
- Handle missing values and outliers intelligently
- Merge multiple datasets into one clean file
- Data validation and quality checks
You'll get a clean CSV or Excel file plus a summary of what was fixed. Send me your data and tell me what needs fixing.
