From a GeoNet question by albow1.
Reading a column data directly from a CSV file and loading all the values in a "select_one" combo on your form in Survey123: such funcionality would be very very useful.
I know how to read the CSV file using "pulldata" function and "calculate" field in my XLSForm to retrieve values according to a key, but in this case there is no key: I just want to load a list of data reading an external file, instead of copying all the data in my "choice" sheet of the XLSForm.
