JSON Visual Editor

Paste or upload any JSON file. Edit it with a clean form. No JSON knowledge required — everything runs in your browser.

What is the JSON Visual Editor?

The JSON Visual Editor parses your JSON object and builds a form with labels, toggles, text fields, and array cards so editors can change values without touching brackets or quotes. The live JSON panel always reflects the form, and you can copy or download the result. Root must be a JSON object (not a bare array).

Who is it for?

Content managers updating CMS or marketing JSON
Translators editing i18n bundles
PMs tweaking feature flags or app config
Anyone who needs valid JSON without a code editor

Privacy

All parsing and editing happens in your browser. Your JSON is not uploaded to Dynamic Duniya servers.

Frequently Asked Questions

Why must the root be an object?

The form generator maps object keys to fields. Bare arrays at the root are not supported in this version — wrap your data in an object (for example { "items": [...] }) and paste again.

How do array items work?

For arrays of objects, each row is a card you can expand, reorder with up/down, duplicate, or delete. Use Add to append a blank row shaped like the inferred item schema.

Is the download file valid JSON?

Yes. The output is produced with JSON.stringify from the live data structure, so syntax errors from manual editing are avoided when you use the form.
