Self-initiated prototype, built with AI assistance. This is not client work and has generated no business revenue.
A browser tool for merging CSV files and reviewing duplicate records. It supports whole-row or selected-key matching, keeping the first or last occurrence, preserving missing-key records separately, and downloading the result, removed duplicates and a JSON audit report.
The screenshot uses invented order data. Local HTTP browser checks verified actual CSV/JSON downloads and the matching rules. A 375px Chinese layout was checked. Files are processed in the current browser without an upload endpoint. Direct file:// use and the Gumroad buyer download were not successfully verified; this case does not promise those paths or unlimited datasets.
