About this gig

Get a repeatable Python script for an agreed file-processing task. Send sample inputs and the exact output you need before ordering.


Basic: 1 CSV or flat JSON, 10,000 rows, 20 columns; one conversion. Standard: up to 5 CSV/XLSX files, 50,000 total rows, 30 columns; merge and up to 3 rules. Premium: up to 10 CSV/XLSX/flat JSON files, 100,000 total rows, 30 columns; up to 5 rules and an exception report. Files must share agreed layouts and be under 20 MB each.


You receive Python source, dependencies, run instructions, output and test results. Uncertain values are flagged, not guessed. Tests cover agreed examples, invalid inputs and repeat runs.


One revision covers corrections against the original layout and rules. No OCR, macros, formula repair, scraping, external APIs, GUI or hosting. Message me for different scope.


I use AI-assisted coding with review and testing. Private data is not sent to external AI services without permission. Never send passwords or payment details.
