About this Gig

Need a clean, import-ready Excel or CSV file? I will clean and standardize your data with careful checks.


What I can do:

Remove exact duplicate rows

Normalize names, text, emails, phones, dates, and amounts

Fix spacing and formatting inconsistencies

Flag invalid or unclear values for your review

Return a cleaned file and a short QA/exception report


Please send the source file and tell me the desired output format and any rules to preserve. I do not work with passwords, payment data, government IDs, medical records, or other highly sensitive personal data.


Delivery is based on row count and starts after I receive the file and requirements. One revision is included in Basic; more are included in higher packages.
