My goal was to import a single item's biblio record as JSON from Crossref data found here:

https://api.crossref.org/v1/works/10.1163/9789004346673-wmd-all

I saved the text as a .JSON file, then used Zotero's File > Import... menu to try and import from that file. I received an error, "The selected file is not in a supported format."

Perhaps I am doing something wrong. Thank in advance for steering me correctly.
