JSON Formatter

Usage

Paste JSON into the input, choose 2 spaces, 4 spaces or Tab indentation, and optionally enable minification or recursive key sorting. Run to inspect and copy clean JSON from the shared output. Syntax errors appear as diagnostics without a copyable result.

FAQ

1. 1.

   What is the difference between formatting, minifying and sorting keys?

   Formatting changes indentation, minifying removes unnecessary whitespace, and key sorting recursively orders object keys without changing array order.

2. 2.

   What happens when the JSON syntax is invalid?

   The input stays editable, the parser reason appears in diagnostics, and the shared output stays empty so invalid JSON cannot be copied as a result.
