About this Gig
Messy CRM export full of duplicates? Message me your file (or a 20-row sample) for a free quote before you order.
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.
FAQ
How do you decide what's a duplicate?
Default: same email, or same phone after formatting, or identical row. First copy kept; every removal logged. Prefer 'keep newest'? Tell me.
Will you delete my data?
Only duplicates are removed from the clean file. Invalid values are flagged, not dropped. Original file untouched. Order files are deleted within 7 days.
Which phone countries?
All. Tell me the main country for numbers missing a country code.
Dates like 04/05/2025?
Say US (MM/DD) or international (DD/MM). Unclear dates go in the report.
Do you verify emails are deliverable?
No - format check only. No test emails sent.
Which formats / CRMs?
CSV, Excel, and mapped imports for HubSpot, Mailchimp, Salesforce, or your template.
Free sample?
Yes - message a sample for a free quote or small preview clean.
