About this Gig

I offer fast, precise data cleaning and merging for spreadsheets of moderate size. If your data is messy, inconsistent, duplicated, or spread across multiple files, I will prepare a clean, reliable dataset ready for analysis or reporting.


What I deliver

  • Cleaning numeric, date and text data
  • Duplicate removal
  • Column validation (mismatches, missing values, invalid entries)
  • Merging of multiple sheets based on unique identifiers (5 merges maximum)
  • Free sample of first 3 rows on request


Who this service is for

  • Small businesses needing cleaner spreadsheets
  • Students and researchers needing consistent datasets
  • Freelancers and analysts preparing data for dashboards
  • Anyone who wants spreadsheets to just work without manually fixing every row


What I need from you

  • Your spreadsheet(s)
  • Notes on preferred formatting or validation rules
  • If merging: which columns to use as keys


Delivery

  • Clean, structured spreadsheet
  • Fast turnaround and clear explanations of changes made
