You will get Messy Excel & CSV Data Cleaned, Merged & Formatted
Rising Talent
Project details
Messy spreadsheets waste your hours and break CRM imports. I clean, deduplicate, standardize, and format Excel/CSV files so they are ready for import, reporting, or analysis.
What sets this project apart:
Every fix is documented: you receive a change log with the clean file, so you always know exactly what was changed and why.
Python (Pandas) + manual spot-checks: fast like a script, reliable like manual work.
Row-count reconciliation and format validation before delivery.
Confidential handling: NDA on request, all files deleted after delivery.
Trilingual support: English, Italian, Russian — handy for EU and international datasets.
What I fix: duplicates, mixed date/phone/price formats, inconsistent case and spacing, broken or merged columns, missing values, import errors.
Perfect for sales teams, e-commerce, and operations who need data they can trust.
