Validate, format, minify and explore JSON with syntax highlighting and a tree viewer.

About JSON Editor

JSON is the universal language of modern APIs, config files, and databases — but raw JSON can be a nightmare to read and debug when it arrives as an unformatted blob. This editor gives you a proper workspace to validate, format, and minify JSON with syntax highlighting that catches errors before they cause problems. The tree viewer lets you explore nested structures visually instead of hunting through raw text.

Paste messy one-liner JSON from an API response and hit format — it instantly becomes readable and properly indented. Switch to tree view to navigate deeply nested objects with expandable nodes. Whether you're debugging API responses, editing config files, or exploring data structures, this editor makes working with JSON significantly less frustrating.
