JSON formatter
Format a JSON object, array, or value with your chosen indentation.
Make valid JSON easier to read.
About this tool
The JSON formatter turns valid JSON into a clean, indented layout without changing the stored data. It accepts objects, arrays, strings, numbers, booleans, and null values. Use it to inspect API responses, read configuration files, or spot misplaced fields in copied data. Choose the indentation size that suits your editor, then copy the human-readable result into documentation, logs, or source code.
