What is the JSON Formatter?
JSON (JavaScript Object Notation) is the most widely used standard format for data exchange between servers and web applications. However, often JSON data comes in a single line (minified) to save space, making it unreadable for a human.
Our tool allows you to paste your raw code and give it a nice structured format (indented) so you can read, analyze and find errors easily. It also works as a validator: if a comma is missing or a bracket is not closed, we will tell you where the syntax error is.
Totally Private and Secure
Unlike other websites, on this page your JSON code NEVER leaves your computer. The entire parsing and validation process happens locally in your browser using native JavaScript. This is vital if you are working with JSON files that contain sensitive information such as customer databases, access tokens or passwords.
