Encoding new championship

You mean all the teams, stadiums and matches?
Yes, that’s how I import the world cup match schedule (csv for Russia 2018 is included in the plugin).

How I create a new csv? I create an Excel file (is easier to edit) and then concatenate all the cells in a row to a string in the correct format. And then copy & paste these lines to a text file.

Ah 🙂
In the Matches screen in the Admin there is a button on top to “bulk change matches”.
