Connect an external data source from excel or XML-file or JSON

I trying to find out how connect an external data source to a template. In this case we need to get date from a car racing, like number, names, times and result. In the best of worlds I would like to use SuperConductor as client. But how can I connect my data source?

Is the racing data file based/database or is it from a api, from the timing system or something else? There are a couple options to get live data in to a template, but the solution depends of the datasource.
Best regards

In this case the best would be if we can connect an excel file. Then we can get filter and sort the data easily.

You can use my Excel Add-In. It works on only Windows Excel. You can use PiwerQuery to get the data and then send it to a Caspar template after processing.

I was looking at it. Can we use it only to send the data? I still want to control eventing with SuperConductor.

Yes, you can send Datasets. That the template picks up.
