Our Confluence app Data Tables for Confluence now supports loading CSV data from remote locations. This allows you to render CSV data from any (public available) URL as Confluence table.
The latest release of our app, adds a new macro “Data Tables CSV (remote)” which allows you to specify a URL to load a CSV file from. Of course, this new macro also supports all other advanced features provided by Data Tables for Confluence to upgrade your standard Confluence tables.
