JsonExport is a professional JSON to Excel/CSV converter that runs fully in your browser. Most tools are slow, insecure, and fail on nested data. JsonExport handles real-world JSON with privacy-first local processing, smart flattening that removes [object Object], and streaming support for 100MB+ files. It includes a simple editor and a data grid to preview before export. Free to use and open source.

I’m building JsonExport, a JSON to Excel/CSV converter that runs entirely in the browser. The main motivation was privacy and scale.
