JSON Tools

APIs and config files still speak JSON, and half the time it arrives as one unreadable line. This category covers pretty-printing, validation, schema checks, diffs, and conversions to CSV, XML, YAML, and TypeScript. Start with the JSON Formatter when you just need to see the structure; reach for converters when the next system wants a different shape.
