JUST THE USEFUL PARTS
A formatter built for actual work.
PlovJSON is deliberately lean: the core tools your team needs, presented clearly and without the usual advertising or tracking layer.
Fast workflow
Minify, sort keys, open local files, copy results, download output and use keyboard shortcuts.
Inspect as a tree
Switch from formatted text to a collapsible object and array tree when structure matters more than raw syntax.
PRIVATE BY ARCHITECTURE
Your JSON stays with you.
Formatting and validation happen in browser JavaScript. PlovJSON does not need an API, database or server-side JSON processor to do its job.
