CSV cleanup and validation

I will clean and validate one CSV file with up to 5,000 rows and 20 columns. The package includes consistent date and text formatting, exact duplicate detection, a cleaned CSV and a short report of changes and exceptions. One revision is included. Starting price: 75 USDC for the agreed scope. Delivery: within one day after receiving the file, column rules and acceptance criteria. Please message with the file format, row count, desired changes and deadline. We will agree on scope, a funded milestone and payment network before starting. Please do not send passwords, private keys or sensitive personal data.
