About this Gig

Messy customer list? I'll send it back clean, consistent, and ready to import into your CRM, email tool, or store.


What I fix:

  • Names: capitalization, extra spaces, "Last, First" order
  • - Emails: case, spaces, common typos, and a flag for invalid ones
  • - Phone numbers: one consistent format, extensions in their own column
  • - Dates, states, and money values put in one format
  • - Duplicates merged without losing notes or data (Standard and Premium)

What you get:

  • Your cleaned file (CSV or Excel, same columns plus an Issues column)
  • - A "needs review" file with only the rows that need your decision. I don't guess at things like a missing email.
  • - A one-page report of every change made

How I work: I use AI-assisted tools and scripts with fixed rules for every change, and I check the output before delivery. Your original file is never altered.


Privacy: your file is used only for your order and deleted 30 days after delivery. I don't take files with medical records, bank or card numbers, or passwords.
