Sorting by question response labels
mTAB has always had a very useful sort feature in the Spreadsheet view, which allows users to sort the data by selecting a range of cells within the same row or column, then choosing Sort from the Spreadsheet ribbon.
Simply select a range of cells in the response text column or the response text row, and choose Sort from the spreadsheet ribbon.
Choose either Ascending, Descending, or Original Order and click OK.
The responses will now sort according to your selection, along with the corresponding rows or columns of data.
