About JSON Editor

A JSON editor is a specialized tool that lets you view, modify, and restructure JSON data through an intuitive interface. Unlike plain text editors, a dedicated JSON editor provides two complementary editing modes: a code view for direct text editing with formatting and minification, and an interactive tree view where you can expand nodes, edit values inline, add new properties, and remove existing ones — all without writing raw syntax.

Our online JSON Editor processes everything locally in your browser, so your data never leaves your machine. Whether you are tweaking API responses, editing configuration files, or building mock data for testing, the tree editor makes it easy to navigate complex nested structures while the code view gives you full control over the raw JSON text.

Frequently Asked Questions

What is a JSON Editor? expand_more
A JSON Editor is a tool designed to help you modify JSON data through a visual interface. It offers a code view for raw text editing and a tree view where you can expand objects and arrays, edit values by double-clicking, add new keys, rename properties, and delete nodes — all without manually managing brackets and commas.
How do I edit values in Tree view? expand_more
Double-click any value in the tree to edit it inline. Press Enter to confirm or Escape to cancel. The editor automatically detects the data type — numbers, booleans (true/false), null, and strings are all handled correctly. You can also double-click object keys to rename them.
Can I add or remove properties? expand_more
Yes. Hover over any object or array node in Tree view to reveal an add (+) button. Click it to insert a new key-value pair (for objects) or a new element (for arrays). Each node also has a delete button that appears on hover to remove it from the structure.
Is my data sent to a server? expand_more
No. All parsing, editing, formatting, and validation happen entirely in your browser using JavaScript. Your JSON data is never transmitted to any external server, making it safe to use with sensitive or private data.
