JSON Formatter

Formats and validates JSON with 2-space indentation and sorted object keys.

Usage

Paste the JSON and ask to format it. The skill validates structure first, then re-emits it with stable key ordering so diffs stay small.

Examples

  • "format this JSON" → returns indented, key-sorted JSON
  • "is this valid JSON?" → returns yes/no plus the first error location

Keep looking

Skills are one crate of 328,083. Ordering is by how many stacks a row turns up in, so the top of any crate is what has actually been picked rather than what has the most stars.
