What does a JSON formatter do?

A JSON formatter formats JSON data with proper indentation and structure to make it easier to read and understand.

What does JSON validation mean?

JSON validation checks whether JSON data follows correct syntax rules, such as proper brackets, commas, and quotes. This tool validates JSON syntax, not JSON Schema.

Can this tool detect JSON errors?

Yes. This tool highlights syntax errors so you can quickly fix invalid JSON.

What is JSON minification?

JSON minification removes unnecessary spaces and line breaks to reduce file size, which can be useful for network transmission.

Who should use a JSON formatter and validator?

This tool is useful for developers, QA engineers, and anyone working with APIs, configuration files, or JSON data.

Is my JSON data sent to a server?

No. All formatting and validation happen locally in your browser. No data is uploaded or stored.
