JSON Formatter & Validator

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It's widely used for APIs, configuration files, and data storage.

Paste your JSON into the editor and the tool will automatically validate it. Valid JSON shows a green indicator, while invalid JSON shows a red indicator with an error message explaining the issue and its location.

JSON minification removes all unnecessary whitespace, indentation, and line breaks from JSON data. This reduces file size for faster network transmission while keeping the data functionally identical.

Tree view displays your JSON as an interactive, hierarchical structure with collapsible nodes. This makes it easier to navigate complex nested data and understand the structure at a glance.

Yes! Use the indentation dropdown to select between 2 spaces, 4 spaces, or tabs. The tool will format your JSON with your preferred indentation style.
