CSVTools converts between CSV, JSON, XML and Excel — all directions — 100% offline. Nothing is uploaded. It streams row by row, so a 5-million-row file converts in flat memory with no row limit. Drag a file in, pick a format, click Convert; leave the output blank and it saves next to your input. Free Demo is a pure converter; Lite and Full add a visual editor to clean, filter, rename, dedupe and reshape — and save reusable jobs. No terminal required.
