Run it in three clear moves
- Add your input, run the tool, and review the result.
Check pasted JSON-LD or script-wrapped schema markup for syntax issues, missing required fields, and common cleanup opportunities. The validator returns deterministic guidance with a normalized code block you can review.
Add the source material and options needed for this run.
The output will stay here while you adjust the input.
Paste JSON-LD to validate the markup.
The essentials stay open. Deeper guidance is one deliberate step away.
Yes. The validator extracts JSON-LD from a script wrapper automatically.
No. It validates structure and common required fields only.
