Put your weekly schedule in from a spreadsheet: each row becomes a class that repeats every week.
Go to Schedule → Import. Click "Download Template" to get the CSV template.
Open the template in Excel or Google Sheets. Fill in class name, day, time, duration, and capacity for each class. One row is one weekly time — give two rows the same class name to run one class on two days.
Click "Choose file" or drag the file in. Klasly will preview the data before importing.
Pick which of your columns holds each field. The Check column in the preview shows any row that would be skipped, and why.
Click "Import Classes". Every row is listed as Added (with how many sessions and the first date), Skipped or Failed, with the reason.
