Get a clean CSV, a record of every change and a script you can run again.

The $75 starter covers one UTF-8 CSV with up to 1,000 data rows and 20 columns, three agreed cleanup or validation rules, and exact duplicate removal. Examples include trimming spaces, standardizing an agreed value format and flagging missing required fields.

You receive: • Cleaned CSV, plus separate duplicate and review files • An audit report that accounts for the input rows and records changes • A reusable Python 3 script and a short run guide

The source file stays unchanged. Ambiguous values go into the review file. I check row counts, rule behavior and edge cases before delivery. Import preparation follows your supplied column and validation requirements; uploading to a live system is a separate scope.

Delivery target: three days after we approve the sample, rules and output format and fund the agreed project. Includes one revision within those rules. Larger files, additional rules, enrichment, fuzzy matching and integrations need a separate quote. Any platform or payment fees are shown separately at checkout.

The linked example is an original demonstration using synthetic records. I use AI tools to help develop scripts, then run and check them. Data processing runs locally; records do not need to be uploaded to an AI service.

Message me with an anonymized sample, the output you need and your deadline. Please have permission to share and process the data.
