About Private JSON Formatter

Format, minify and validate JSON in your browser. Local files and quoted-ID examples; rejects unsafe integers. No payload uploads. Engine1-owned independent tool on a shared Engine1 installation; not open source; free browser use. Engine1 rejects unsafe numeric integers and silently uses last duplicate key, rather than lossless formatting. Do not claim best precision or JSON Schema support.
