JSON Formatter
Beautify JSON for readability or minify it into one line, and validate its syntax. If there's an error, it shows the location and cause. All processing happens in your browser, so the data you enter is never sent out.
How to use
Format adds indentation and line breaks to make JSON easy to read. Minify removes whitespace to compress it into one line and reduce size.
Validate checks whether the JSON syntax is valid and, if there's an error, tells you the cause.
