I clean CSV / Excel contact lists so they import without drama:

  • Dedupe by email, phone, or identical row - every removed row listed with the row it matched
  • Phones to one E.164 format (e.g. +14155550123)
  • Emails trimmed + lowercased; invalid format flagged (I don't send test mail)
  • Dates unified; unclear dates like 03/04 flagged, never silently guessed
  • Names / companies: consistent caps (O'Brien, McDonald), extra spaces gone

You get: clean CSV/XLSX, before/after count, removed-duplicates log, issues list with original row numbers. Nothing silently deleted. Your original file stays untouched.


Cleaning is automated and AI-assisted; I review the report before delivery. I don't buy, scrape, or add contacts.


Confidentiality: used only for your order, deleted within 7 days of delivery.
