About this Gig

Is your data a mess of duplicates, inconsistent formatting, and broken relationships? I'll clean it up so it's accurate, structured, and ready to use.

I work daily with SQL databases and Excel/CSV data as part of my day job, handling real business data not just sample exercises. I can help you with:

  • Removing duplicate records and inconsistent entries
  • Standardizing formats (dates, names, addresses, categories)
  • Fixing broken relationships between tables
  • Validating data against business rules
  • Converting messy Excel/CSV files into clean, structured spreadsheets or SQL tables

Send me your file or database access, tell me what "clean" should look like, and I'll deliver data you can actually trust and use.
