I’ve created a public calendar on Google and wanted to use it’s JSON-File to embed it on my website. You can see it here.
I can’t get it running AND what make’s me think the problem might not be my JS-Code is that JSON-Formatter like jsonformat.com or jsonprettyprint.com can’t render the file. Is this normal?
URL you provided returns not JSON but JS which actually emits JSON in the end. Open it in browser and check.
