About this Gig
Messy business data should not be cleaned by guessing.
I clean Excel, CSV, and CRM exports with duplicates, inconsistent formatting, missing values, or conflicting records.
Suitable for customer lists, lead databases, CRM exports, product catalogs, vendor lists, and business spreadsheets.
I can standardize names, dates, phone numbers, emails, company names, statuses, IDs, columns, spaces, and formatting.
Possible duplicates, conflicting values, and suspicious records are flagged for human review instead of being silently changed.
You receive:
a separate clean output file
validation results
a review queue with reasons
a concise cleanup summary
MESSY DATA CLEAN OUTPUT VALIDATION REVIEW QUEUE SUMMARY
Your original file remains unchanged.
Package limits:
Basic: up to 500 rows
Standard: up to 2,500 rows
Premium: up to 10,000 total rows
Please message me before ordering if your data exceeds these limits or requires custom validation rules.
FAQ
What files can I send?
You can send CSV files, Excel spreadsheets, or file-based CRM exports. Please anonymize unnecessary sensitive data before sending.
Do you need access to my CRM?
No. I only work with the files you provide. Live CRM, database, or account access is not required.
Will you automatically fix every issue in my file?
No. Clear formatting and validation issues can be corrected, but ambiguous or conflicting records are flagged for review instead of being guessed.
Will you change my original file?
No. Your original source file remains unchanged. You receive a separate cleaned output.
Can you remove duplicate contacts?
Yes. Exact duplicates can be handled according to your instructions. Possible duplicates are flagged for review instead of being silently merged.
Can you validate my data against my own rules or source file?
Yes. If you provide clear validation rules, required fields, or a reference/template file, I can use them during the cleanup.
