Played around a lot with this plugin, but it just doesn't work well. For example, I need dates in my worksheet, but the plugin cannot handle them. Even in the example app editor, dates are just text values and the users cannot interact with them. Very bad.

You just have to be careful with how you set the JSON - but it works well. Maybe there's no documentation, but you can learn from the example app. Debug mode might help, if the file fails to download double-check your JSON - most likely place for error.

After an hour of setting everything up, it simply didn’t work. The plugin has absolutely no documentation guiding its use. I copied it exactly as shown on the demonstration page, and it just didn’t work.
