🧠 How It Works
Open the template preview.

Click ‘USE TEMPLATE’ to create your copy.

Choose your tournament type (e.g., 8s for 8-player single elimination).

Enter player names in column A.

Use the ‘randomize order’ button or keep it custom.

Check winners as rounds progress.

Sit back and watch the brackets fill in automatically.

Note: Please do not rename the sheets. Script functionality depends on specific sheet names (e.g., 8s, 16d).
