The form we have created is very big. There are multiple skip logic questions. When we want to view the data collected in excel the questions which are not answered and hence skipped also show up making the sheet very big. While data cleaning multiple columns will have to be deleted which can be a tedious process, hence, I would like support in making the data sheet concise. Please help me with this.
