CatalogClean — Python and JavaScript Automation Demo

Self-initiated automation example using synthetic product data.

Created a Python command-line utility and a JavaScript browser interface for cleaning CSV catalogues. They normalise SKU and name fields, validate prices and stock, identify duplicates, and separate accepted rows from a review log.

The supplied seven-row sample produces four clean records and three records for review. The browser supports quoted fields and comma/semicolon input. Exported text is protected against spreadsheet-formula prefixes. The Python version preserves the input and refuses to overwrite existing output files.

Deliverables: reusable source, sample input/output, review log and run instructions. Files are processed locally; no third-party account or paid API is required.
