Why desktop?
Handles 1 GB+ files
Native Rust streaming parser processes huge JSON dumps without loading the whole file into memory. The browser can't do this.
Batch + folder-watch
Drop dozens of JSON files into a folder. The app watches for new files and converts them to XLSX/CSV automatically.
Fully offline
All processing happens locally. Your files never leave your machine. Works on air-gapped networks.

One-time payment, lifetime access, all future updates included.
