Ready. Your working data stays in this browser.
Use Schema Markup Inspector when you need to inspect pasted JSON-LD for valid JSON, schema types, identifiers and commonly required public fields. The result is immediate and easy to verify before you reuse it.
Enter the values requested by Schema Markup Inspector. The browser validates the input, performs the calculation locally and produces a copyable result with clear errors.
A practical use is to run Schema Markup Inspector on a small sample first, confirm the output, and then process the complete value or list.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
