install jsonyo. keep the JSON workbench where you already work.
jsonyo ships as a browser extension, a WordPress wp-admin plugin, and a free CLI. Pick the surface that matches your day: browser tabs, wp-admin, or terminal. Everything runs locally. Zero data leaves your browser. If you get stuck, the support page tells you exactly where to go next.
works where you already are
jsonyo avoids the "open another tab" tax. if you are in a browser, use the extension. if you live in wp-admin, use the plugin. if you are in a shell, use the CLI.
zero data leaves your device
the browser surfaces run entirely locally. no upload, no analytics, no hidden API hop. that's the point for REST payloads, webhooks, and private staging data.
more than pretty-printing
jsonyo does format, validate, JSONPath-style query, diff, stats, and minify. it solves the actual workflow instead of stopping at indentation.
pick the surface
browser extension for tab work, WordPress plugin for wp-admin, CLI for terminal-first debugging. the toolchain stays the same.
install from the store
use Chrome, Firefox, or Edge for the extension. if you're in WordPress, go straight to WordPress.org. no account is needed for the free surfaces.
start with a real payload
paste REST output, ACF JSON, theme.json, or a webhook body. validate it, query it, or compare two versions in one pass.
Best next click: if you are deciding, use the WordPress compare page first. It explains why the plugin belongs in wp-admin, while the browser comparison shows how jsonyo stacks up against plain JSON formatter tools. If install gets stuck, open support / docs.
open the popup, inspect the current page, and keep JSON work anchored to the page you are already on.
REST responses, ACF exports, theme.json, and webhook payloads live inside the dashboard instead of a separate tab.
same engine, terminal-first. use it when you want output you can pipe, diff, or automate.
jsonyo does not need a cloud round-trip for its core workflow. that keeps private and internal payloads private.
chrome web store
install for Chrome, Brave, or Opera. the extension popup opens immediately after install.
firefox add-ons
install for Firefox or LibreWolf. same popup, same workflow, same zero-data promise.
microsoft edge add-ons
install for Edge if that's your default browser. no workflow change required.
support
one inbox for bug reports, feature requests, privacy questions, and install help. the fastest route when something blocks your install.
install path guide
compare the WordPress plugin and browser extension before you choose a surface. the guide points you to the right install path fast.
