#About JSON Editor
Free online JSON editor. Edit JSON data interactively — add, delete, and modify keys and values with a visual tree editor that syncs to raw JSON output. This tool runs entirely in your browser — your data is never sent to a server. Just paste your input, get instant results, and copy with one click. No sign-up or installation required.
#FAQ
Can I add nested objects and arrays? ▾
Yes, you can add child nodes to any object or array, change value types between string, number, boolean, null, object, and array, and build complex nested structures visually.
Does the editor validate my JSON? ▾
The editor always produces valid JSON since edits are made through structured controls rather than free text. The raw JSON output updates in real time as you make changes.
