Dear Florence,
So far this is not possible to change. The order of columns is the order to the fields on the survey.
If you need the fields to be ordered alphabetically there is a very simple solution in Excel!
Just open the CSV exported from Collect Earth in Excel (remember these are CSV delimited by commas, which sometimes in Excel does not look right - the columns are mixed - you then need to use the Data-> From text see [LINK][1])
Then go to the Data tab and click on the short menu icon, then on the dialog choose sort options and there pick the option "Sort left to right". Finally you chose that you want to use the row 1 (the attribute names row) to sort by. When you click OK the columns will rearrange following the alphabetical order of the attribute names.
