I will clean, dedupe, and standardize your excel or CSV contact list
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.
Not sure which package fits? Send me the row count and a screenshot of the first few rows.
FAQ
Which file types do you accept?
CSV, Excel (.xlsx, .xls), and Google Sheets exports. I deliver in the same format you send.
How do you decide what counts as a duplicate?
The same email address, or the same name and phone number when there's no valid email. The report lists every merge, so you can check them.
What if a value is missing or wrong, like an email?
I don't invent data. Those rows go into the "needs review" file so you can decide.
Do you use AI?
Yes. I use AI-assisted tools and scripts with fixed rules, and I check every delivery against your file before sending.
What data won't you take?
Medical records, bank or card numbers, Social Security or SIN numbers, and passwords. Your file is deleted 30 days after delivery.
