jq Playground offers a tiny, honest subset of jq-style filters so you can chain , .key, .[], and .[0] against JSON without pretending to ship full jq.
What jq Playground does
Parses a small filter grammar and returns JSON text.
- Identity .
- Object keys .name
- Array iterate .[]
- Numeric index .[0]
- Simple chains like .items[0].name
Who jq Playground is for
- Developers drafting quick probes
- DevOps checking JSON payloads
- Students learning jq basics
- Anyone without a local jq binary handy
How to use jq Playground
1. Paste JSON.
2. Enter a tiny filter starting with a dot.
3. Click Run.
4. Copy the result for notes or fixtures.
Features
- Best-effort chaining
- Clear unsupported syntax errors
- Local evaluation
- Companion JSON Path Tester
Examples
- .items[0].name on a list of objects.
- .[] to flatten a top-level array into multiple values.
- . alone to pretty echo parsed JSON.
Tips and limits
- No pipes, maps, selects, or functions.
- Not a substitute for real jq on complex queries.
- .[ ] empty brackets must appear as .[] in the filter string.
- Invalid JSON fails before the filter runs.

FAQ
Is this full jq?
No. Only a tiny subset is implemented on purpose.
Are pipes supported?
No. Use simple chains only.
Is data uploaded?
No. Filters run in your browser.
Extra notes
jq Playground runs entirely in your browser so drafts and secrets never need to leave your device for processing. Keep a backup of long outputs in your own notes if you rely on them for production servers or live events. Accessibility friendly labels come from the module UI strings, and the layout follows the shared BeeForge .bf-tool shell for consistent spacing and buttons.
Support for developers, marketers, and everyday users is the same client-side model: open the page, configure options, copy or download, then paste into your workflow. BeeForge related links on the tool page point to companion utilities so you can move between related generators without hunting the hub.
When you share results with a teammate, paste into a ticket or gist rather than screenshotting alone, so the text remains searchable. If a browser privacy mode blocks clipboard helpers, select the output manually. Local processing also means the tool works offline after the page and scripts have loaded once.
Validate generated configs or hashes in a staging environment before production use. Prefer regenerating secrets after any accidental paste into chat. For teaching sessions, walk through one sample input end to end so students see how live updates and copy buttons behave together.
Bookmark the tool page if you use it weekly. Small habit changes like consistent naming and clear file downloads save more time than hunting another converter. Prefer regenerating after you change inputs rather than editing outputs by hand when the source fields still exist.
