The first row may be a header — if it says name and level, it is skipped.
Level is matched by name against this championship's levels
(Level 1, Level 2, Level 3, Level 4 and so on).
Anything it cannot match falls back to Level 1, and you can change it in the table.
Email may be blank. Only the name is required — a row with no name is ignored.
Importing adds to the roster, so you can bring in two files.
