What is this tool?
JSON (JavaScript Object Notation) dominates REST APIs, browser storage schemas, and automation glue code. Readable indentation accelerates debugging ambiguous keys; minification trims bytes when bandwidth matters. Calcxzo validates syntax client-side so sensitive payloads never traverse our servers during typical usage.
How to use
Paste JSON and choose Pretty or Minify. Errors surface via the status line with parser hints — fix commas or quotes and retry.
