I will clean, deduplicate and format your CRM or contact list data
About this Gig
Messy contact data costs you deals. Duplicates, broken emails, and inconsistent formatting make your CRM unreliable and hard to import.
I clean it up so your list is accurate, consistent, and ready to use.
What I fix:
- Duplicate contacts merged or removed
- Names, emails, and phone numbers standardized
- Inconsistent capitalization and spacing corrected
- Columns split or merged (e.g. full name into first/last)
- Date formats unified
- Invalid emails flagged
- Missing fields identified
You send your export (Excel, CSV, or Google Sheets). I return a clean, deduplicated file plus a summary of exactly what changed. Your original is never altered you get a new, clean copy.
Works with exports from HubSpot, Salesforce, Zoho, Mailchimp, Shopify, or any spreadsheet.
Not sure which package fits? Send me a sample and I'll tell you honestly before you order.

FAQ
Is my data kept private?
Yes. Your file is used only to complete your order and deleted after delivery. I'm happy to work from a sample first, or you can anonymize sensitive fields before sending.
What file formats do you accept?
Excel (.xlsx), CSV, or a shared Google Sheet. I deliver in whichever format you need for your CRM import.
What if my list is bigger than 15,000 rows?
Message me before ordering and I'll set up a custom offer for you.
Do you fix the data or just formatting?
I clean structure and formatting, remove duplicates, and flag issues like invalid emails or missing fields. I don't research or invent missing data unless you request it as an add-on.
