I want to give each respondent a unique url in a descriptive text question and the end of the survey, recording which link was given to which participant. I have a list of links in an .csv file. Is there a way to do this with piped text? More broadly, is there a way to insert piped text based on external data? For instance, I could imagine wanting to ask a question like in your area (based on zip code) home values changed by x% in the last year, where I have a spreadsheet of house value changes for each zip code.
