Messy CSV Cleanup Dedupe, Normalize & Validate

Got a CSV export full of duplicate records, inconsistent dates, broken columns or messy formatting?

I will clean and standardize your data so you receive a structured CSV or Excel file that's ready to use, filter or import into another system.

✓ GUARANTEE

If I can't deliver exactly what's described in this listing, you get a full refund. No questions, no delay.

WHAT YOU GET

Depending on your file, I can:

• Remove duplicate records
• Normalize date formats
• Standardize phone number formats
• Standardize addresses
• Trim unnecessary spaces and characters
• Split incorrectly combined columns
• Clean inconsistent values
• Flag invalid or suspicious records
• Organize columns into a consistent structure

You receive one cleaned CSV or Excel file with the corrected data.

WHAT I NEED FROM YOU

After purchase, please send through eBay:

• Your CSV file
• A short explanation of what the data represents
• Which column should identify duplicate records, if known
• Your preferred date, phone or other formatting standards, if applicable

If you don't specify a formatting preference, I will use a consistent practical format throughout the file.

VALIDATION

Validation means checking the supplied data for obvious structural problems and inconsistencies.

Records that cannot be safely corrected from the information provided will be flagged rather than guessed or deleted.

TURNAROUND & REVISION

Delivery: within 24 hours

One revision within the original order scope is included if something from the agreed cleanup was missed.

WHAT'S NOT INCLUDED

• Researching or finding missing data
• Creating information that isn't present in your file
• Manual verification against external databases
• Advanced data analysis or reporting
• Database migrations or system integrations
• Custom software or automation development

IMPORTANT

Your original data is not changed blindly. When a value cannot be reliably determined from the supplied information, it will be flagged instead of invented.

This service is ideal for messy exports that need to be cleaned before imports, migrations, analysis or everyday spreadsheet work.

One-time service. No subscription. Digital delivery through eBay.
