JSON Formatter and Validator
Validate, format, or minify JSON locally, compare sizes, and download the result.
JSON is processed locally and is not sent to Utilsha.
Format, validate, or minify JSON
The tool parses JSON before transforming it. Formatting adds 2- or 4-space indentation; minifying removes unnecessary whitespace without changing the data.
What valid JSON means
JSON requires double quotes around keys and strings and does not allow trailing commas. If the parser finds a problem, its message is shown instead of producing an incorrect file.
Size and download
Metrics use UTF-8 bytes. Formatted JSON can be larger than its source, so the comparison explicitly reports a smaller, equal, or larger result.
