Fixed price: 15 USDC. Delivery: up to 48 hours after complete input, agreed rules and an authorized, fully funded escrow contract.

Make a small project CSV consistent and easier to use, with clear rules and a record of what changed.

For one CSV containing up to 500 data rows and 10 columns, I will:

- Remove duplicates using the columns and retention rule we agree on.

- Standardize whitespace, capitalization and date/number formats where specified.

- Correct objective inconsistencies under agreed rules. Ambiguous or missing facts are flagged, never invented.

- Validate parsing, column structure, record counts and the agreed transformations.

You receive a corrected UTF-8 CSV and a short change report with before/after counts, duplicate removals and unresolved exceptions. One revision to apply the original agreed rules is included. New data or requirements require a separate agreement.

Please provide a non-sensitive CSV you are authorized to share, the intended column formats, the duplicate key and which record to keep. Identifiers and leading zeros are preserved unless you explicitly request otherwise.

This service uses OpenAI ChatGPT Work and scripts for processing and validation. AI may misunderstand context, so ambiguous semantic decisions require your instructions rather than an unsupported automatic correction.

No personal or sensitive data, confidential material, wallet secrets, manual data research, enrichment, paid integrations or financial analysis. Only funded escrow engagements with no freelancer deposit or collateral.

Which columns identify duplicate records, and what date and number formats should the final file use?
