Runs entirely in your browser — nothing you type is sent to a server or stored.
How it works
Validate your schema in three steps
Paste your JSON-LD
Drop in the markup from your page's <script type="application/ld+json"> tag, or load one of the sample snippets to see how it works.
Run the validator
We check that your JSON parses, that @context and @type are present, and that each type carries the fields Google expects, fully in your browser.
Fix and ship
Errors and warnings are listed field by field, so you can patch your markup and re-validate until it passes, then publish with confidence.
Common questions about JSON-LD validation
Paste your JSON-LD into the validator above and run it. The tool first checks that your markup is valid JSON, then confirms @context points to schema.org and @type is set, and finally checks the required and recommended fields for your schema type. Everything runs in your browser, your markup never leaves your device.
The most frequent issues are a missing @context or @type, malformed JSON (a stray comma or unquoted key), and missing required fields, for example an Article without a headline, or a FAQPage whose mainEntity items lack an acceptedAnswer. This validator flags each of these with the exact field that needs attention.
Google reads your structured data when it crawls a page and only shows rich results when the markup is valid and contains the fields it needs. This tool mirrors those expectations so you can catch problems before Google does. For final confirmation, you can also run Google's own Rich Results Test.
Each schema type has fields Google requires for eligibility and others it recommends for richer results. Article requires a headline and author and recommends datePublished and image; FAQPage requires a mainEntity of Question items. The validator marks missing required fields as errors and missing recommended fields as warnings.
No. The validator runs entirely in your browser. Nothing you paste is sent to a server or stored, your data never leaves your device.
