Why JSON Minification Can Help
Readable JSON often contains spaces, line breaks, and indentation that are useful for people but unnecessary for machines.
Minification removes this presentation whitespace while preserving the JSON structure and values. Minification is different from validation or formatting and should not be treated as a way to repair invalid JSON.
