JSON Tools
A focused set of utility-first JSON tools for formatting, validation, and debugging. The cluster starts narrow on purpose so the core workflows stay fast and maintainable.
Current tools
Two production-ready tools for the core JSON workflows: formatting readable output and validating syntax.
Guides that support the JSON cluster
Use the supporting content when you need examples, quick explanations, or common failure patterns.
How to Format JSON
A direct workflow for turning dense JSON into readable output.
How to Validate JSON
Check syntax safely and interpret parse errors faster.
Common JSON Errors
A quick reference for the mistakes that break JSON most often.
Invalid JSON Examples
Broken snippets with fixes so you can spot failure patterns quickly.
FAQ
Which JSON tool should I use first?
Use the validator first when you suspect a syntax problem. Use the formatter first when the JSON is already valid and you just need readable output.
Does StructKit support advanced JSON features in V1?
No. V1 is intentionally narrow: formatter, validator, guide content, and the shared internal linking around that cluster.
Can I use these tools for JSON-LD or API payloads?
Yes. The formatter and validator work well for API responses, structured data markup, configs, and other plain JSON text.
