Messy spreadsheet? I'll turn it into clean, usable data.


I'm a data engineer who works with spreadsheets and databases every day. Send me your messy Excel or CSV file and I'll return a clean, consistent, ready-to-use version - fast.


What I can do for you:

  • Remove duplicates, blanks, and errors
  • Merge multiple files or sheets into one
  • Split or combine columns (names, addresses, dates)
  • Fix inconsistent formatting, encodings, and date/number formats
  • Standardize text (capitalization, trimming, spelling of categories)
  • Reformat and reorganize so the file is ready for import or analysis


Every order includes a quick summary of what was cleaned and any issues found.


Why me: I do this professionally with much larger datasets. Your file is a quick job for me, done properly the first time.


Not sure if your file fits? Message me first - I'll take a look and tell you honestly before you order.
