JSON Content Importer for WordPress
JSON is a wonderful data format for structuring and transmitting data in web applications. Plenty of your favorite web applications allow you to export and import data in this format. Thanks to JSON Content Importer, you can display live data from a JSON feed.
You can define URL, template, cache time and other settings for your JSON feeds easily. The plugin plays well with Gutenberg but you can also integrate it into your site with a custom shortcode. The pro version has even more features with a more flexible template engine, widget support, and support for more parameters.
