JSON Formatting

How to convert JSON to a single line?

Converting JSON to a single line, called minifying, removes all unnecessary whitespace, indentation, and line breaks. This reduces file size for faster transmission and storage. Use our JSON Formatter at jsonconsole.com/json-formatter which offers both beautify and minify options. Simply paste your formatted JSON and select the minify option to compress it into a single line. Minified JSON is ideal for production environments, API responses, and reducing bandwidth usage. The process preserves all data while removing only cosmetic whitespace. For example, a nicely formatted multi-line JSON becomes a compact single-line string. While minified JSON is harder for humans to read, it is perfect for machines and reduces payload sizes significantly. Our formatter can instantly switch between minified and beautified versions, letting you work with readable JSON during development and minified JSON for production.
