If the sheet has its own headers (e.g. Start time or Speaker email), open the column mapping in the preview and pick the right column for each field. Leave the ones you don't need as – ei käytössä – (not used).
- Required: date, time, email, and first and last name or a name in one column.
- Choose Käytä näitä sarakkeita (use these columns). The mapping is remembered for this event, so the next import uses it automatically.
- Dates and times may be date or time cells in the sheet.
