Limitations & Compatibility
Frequently Asked Questions
What is a JSON formatter?
A JSON formatter takes an unformatted or minified JSON string and adds consistent indentation and line breaks, making it much easier for developers to read and debug the data structure.
What is a JSON validator?
A JSON validator checks your text against the official JSON specification. It verifies that quotes match, brackets close correctly, and all data types are valid. If there is a syntax error, the validator will alert you.
Does this JSON formatter upload my data?
No. All processing happens entirely locally in your web browser. Your JSON data is never sent to our servers.
Can I minify JSON?
Yes. The Minify operation removes all insignificant whitespace, line breaks, and indentation from valid JSON to reduce its file size.
Does this tool support JSON comments?
No. Standard JSON does not support comments. This tool enforces strict standard JSON validation.
