Messy spreadsheet exports are hard to trust. I clean a CSV export, standardize dates and amounts, identify duplicates, and separate rows that need your review.

You receive a clean CSV/XLSX file, a short quality report and the rules used. My synthetic demo processes 13 rows: 6 accepted and 7 flagged, including one duplicate. It is a test example, not a client case study.

Starting scope: one CSV format, one agreed set of rules, one correction round. From 400 PLN, a delivery window of up to 1 week after the sample and acceptance rules are agreed (typically 2 working days for a straightforward single-format CSV). Please send an anonymized sample and tell me which fields must be unique. Other file formats and larger scopes are quoted separately.

I use AI to build the workflow and check the result with automated tests and record counts. We can handle the whole brief and delivery in writing; no meeting is needed.
