Ted Mader 2025-09-14: Very helpful!
AdWords Robot 2025-08-17: Simple and effective structured data tester within the browser and loaded webpage. Works with realtime changes as well, which is great if JSON-LD is loaded via a script.
Thomas Dietrich 2025-07-23: A good idea, but it has issues with German umlauts (ä, ö, ü). It sends incorrectly encoded data to the test tool. The preview inside the browser looks correct, but as soon as it opens https://search.google.com/test/rich-results, the encoding is broken.
Alper Ortac 2025-02-07: This is exactly what I was looking for. Feature request: A preview on how the found entities would look like on Google. Do you think something like that would be possible?
Chris Narowski 2024-11-12: Works great for offline pages as well.
Pixel Patchwork 2023-10-19: Just what I was looking for! It quickly shows the JSON LD on any site without the hughe query time that the Google JSON LD test tool requires. Perfect for tweaking your JSON LD!

Mario Raider 2019-02-02: Shows amount of json-tags on plugin icon - very useful for quick view! Click on plugin-icon and get infos on canonical-url and robots-indexing-information. Direct link to google structured-data testing tool for deeper insights. Very useful - thanks for developing Mr. Kanzler!
