I will clean, deduplicate and standardize your excel or CSV data
Master Data specialist Clean files zero guesswork
About this Gig
Messy data costs you money. Duplicate customers get emailed twice, reports dont add up,
and your CRM import fails at row 4,012.
I fix that.
I work with master data and Excel every day in a corporate environment, and Ive built an AI-
assisted cleaning pipeline that lets me deliver in 48 hours what normally takes a week of
manual work without the manual errors.
What I clean:
- Duplicate records exact AND near-duplicates (John Smith vs Smith, John)
- Inconsistent formats: dates, phone numbers, addresses, currencies, casing
- Whitespace, special characters, broken encodings (é, â and friends)
- Blank rows, junk columns, merged-cell chaos
- Multiple files that need to become ONE reliable master file
What you get:
- Your clean file in Excel or CSV, ready to import anywhere
- A change report documenting every single fix youll see exactly what changed and why (no black box)
- Fast turnaround and clear communication
- Perfect for: CRM/ERP migrations, email marketing lists, product catalogs, customer databases, financial records, survey data.
Send me a sample of your file (even 20 rows) and I'll tell you exactly what I can fix before
you order.
FAQ
Is my data confidential?
Absolutely. Your files are processed privately, never shared, and deleted after delivery upon request. NDA available for Premium orders.
What file formats do you accept?
Excel (.xlsx, .xls), CSV, TSV, and Google Sheets exports. Have something else? Message me first.
My file is bigger than the package limit. What do I do?
Message me before ordering — I’ll send a custom offer based on row count and complexity.
How do I know what you changed in my data?
Every order (Standard and up) includes a change report: a side-by-side log of every modification. Nothing happens to your data silently.
Can you merge duplicate records instead of just deleting them?
Yes — for fuzzy duplicates I can merge records keeping the most complete information from each. Specify this when ordering.
