Description from extension meta

View JSON documents in the browser.

Image from store JSONView
Description from store Normally when encountering a JSON document (content type "application/json"), the browser simply shows plain text. With the JSONView extension, JSON documents are formatted, highlighted, and arrays and objects can be collapsed. Even if the JSON document contains errors, JSONView will still show the raw text. Once you've got JSONView installed, check out http://jsonview.com/example.json to see the extension in action!

  • (2019-12-03, v:2.1.0) Daryl Kell: Request: copy path feature
    When you hover over an item, the hover/title text gives you the path. It would be helpful if this hover text was able to easily be copied, so a user can easily grab the reference. Thanks for your hard working on this extension; I use it all the time.

    I can't get JSONVIEW doesn't seem to work when opening local json files. I've fiddled around config and can't find anything to this end. Am I missing something? Is JSONVIEW meant to work for local files? Thanks
