Hi @fieldwork19,
Please have a look at the image attached below. It’s a sample of the xls dataset downloaded from the KoBoToolbox server.
1 viz. Survey is the sheet containing the main dataset. 2 viz. D_O_O is the sheet containing the repeat group responses. Similarly, 3 viz. DO_O is the sheet containing the repeat group responses.
So, generally in a dataset you will have only one 1 sheet while you may have many sheets like 2 or 3 (depending upon your questionnaire).
Besides, please note that if you do not have repeat group questions in your questionnaire or if you do have but have not filled up the same due to skip logics you will not see the same.
GOOD DAY!
