Lantern Counter
Upload a roster CSV from UltraCamp. Create one by exporting for excel with Reservation History (required) and Lodging (optional) selected. This tool counts each
camper's distinct valid summers and adds a LanternYears column.
Secure. The roster you open here is processed entirely on your device, in your browser. No data is uploaded, stored, or sent anywhere.
