What is a live JSON Editor?
Unlike a formatter where you click a button to see output in a second panel, this editor validates your JSON continuously as you type, right in the same panel you're editing — closer to how a code editor with JSON linting built in would behave.
How to use this JSON editor
- Start typing or paste JSON directly into the editor.
- Watch the status bar below — it updates live as valid or invalid.
- Use Format or Minify to rewrite the content in place at any time.
Frequently asked questions
Does the editor save my JSON anywhere?
No. Everything stays in your browser tab's memory. Refreshing the page clears it, and nothing is ever sent to a server.
How is this different from the JSON Formatter?
The formatter is a two-panel tool: input on the left, output on the right. This editor is a single panel you edit directly in place, with live validity feedback as you type — closer to editing a real JSON file.
Can I format and minify without leaving the editor?
Yes — the Format and Minify buttons rewrite the content of the same editor panel in place.
