I will clean and standardize one small CSV using rules we agree on, then deliver the corrected CSV with the original preserved.


$15 covers 1 CSV up to 100 input data rows (1 row = 1 item; header excluded), 20 columns, 2MB and 5 agreed operations. Delivery: 5 days, with 1 corrective revision within the agreed scope.


Available operations: requested whitespace cleanup, date or decimal normalization, exact value replacements, and removal of duplicate original full rows, keeping the first. Labels and other values stay unchanged unless you request a specific rule. I do not guess what ambiguous values mean.


Tell me your desired result and share a safe sample. I will clarify ambiguities before applying changes. No JSON or configuration files needed. Processing is AI-assisted, with seller review. Unresolved questions are discussed before final delivery; a preview is not the completed service.


Public or synthetic, nonconfidential data only. Do not send personal, financial, health or minor-related data, passwords or credentials. Database work, imports and integrations are excluded. HTML review tools are internal, not a promised deliverable.
