JSON
Filter JSON is a JSON tool that takes json input and returns json output. It runs entirely in your browser, so your input never leaves your device.
Step by step
5 steps, all from the panel above — nothing leaves your browser.
Type or paste your json into the input panel above — it keeps a running character and line count as you type.
Adjust the 5 tool options — JSON indentation, Invert, Field, Match, Value.
Run it — the work happens in your browser, so nothing is uploaded.
The result appears in the output panel as json output. From there you can copy it with one click, download it as a file.
