About JSON Minifier
Removes all insignificant whitespace and line breaks from a JSON document while preserving its exact structure and values. Input is parsed first, so invalid JSON is rejected rather than mangled. Handy for shrinking payloads, embedding JSON in query strings, or preparing fixtures.
