About this Gig
Messy customer lists cost you money: duplicate records inflate your email
sending costs, malformed addresses bounce, and inconsistent formats break
every segmentation you try to build.
I fix that properly, not with a find-and-replace.
WHAT YOU GET
· Duplicate detection with fuzzy matching (not just exact matches "Mario
Rossi" and "M. Rossi" at the same address get caught)
· Email and phone validation, syntax and format normalisation
· Standardised addresses, names, dates and country codes
· A cleaning report: what changed, how many records, and why
HOW I WORK
Every job starts with a profiling pass on your file, so you know what's wrong
before I touch anything. You get a preview of the changes before they're
applied. Nothing is deleted without your confirmation.
Your file is never uploaded to third-party services. If you handle personal
data under GDPR, I can work to your retention and minimisation rules.
Send me a sample of your file and I'll tell you honestly what can be
recovered and what can't.
FAQ
What file formats do you accept?
CSV, Excel, JSON, or a SQL dump. If your data lives in a database I can work from an export — I don't need access to your systems.
Will you delete records without asking?
No. Every job runs in dry-run first: you see exactly what would be removed or changed, and you approve it before anything is applied
I have personal data and I'm worried about GDPR.
Reasonable. I map which columns hold personal data and apply your retention rules. Your file is not uploaded to any third-party service
My file is bigger than 500,000 rows.
Message me before ordering and I'll send a custom offer.
