jsonyo — format, validate, query JSON anywhere — including wp-admin.
jsonyo is a JSON power-tool that lives in three places: an npm CLI (already shipped), a browser extension (in build), and a WordPress plugin (right after the browser extension). free everywhere, no premium tier, no signup. just JSON.
shipping order: browser extension first, WP plugin in parallel.
jsonyo currently exists as an npm CLI package. The browser extension comes first — it expands the audience 10× (anyone debugging JSON in DevTools, not just Node devs). The WordPress plugin reuses the same code and ships in parallel after the browser visual is locked. Free at every tier, no premium upsell.
what the WP plugin will do
paste JSON, get prettified or minified output. invalid JSON shows the exact line + character that broke parsing.
hit any WP REST API endpoint from wp-admin, see the raw response prettified, copy or download as .json.
query into nested JSON with JSONPath or jq-style selectors. inspect deeply-nested ACF fields, custom-post-type meta, anything.
validate post meta or custom-field JSON against a schema. catches the "ACF returned a string when I expected an array" bugs before frontend renders.
upload CSV of products or posts, validate each JSON column against a saved schema. one click, one report.
format / inspect Gutenberg block JSON, theme.json, plugin export/import bundles. all in wp-admin, no separate tab.
shipping roadmap
npm install -g @v0idd0/jsonyo. 18 commands: validate, format, query, diff, merge, flatten, convert (YAML/TOML/CSV/XML), generate types. @v0idd0/jsonyo on npm
Chrome / Firefox / Edge. Manifest V3. ~10-14h dev + huashu visual concept session + CWS submission. ETA: 4-6 weeks.
parallel to browser extension. shares brand-spec.md and visual canon. ETA: 6-8 weeks from now (after browser extension visual approved).
we don't have an email-capture form. follow on the channel you're already on. or just install the CLI today — same engine, terminal-first.
