Xola's Custom Report Builder offers suggested reports, including the Questionnaire Report, which allows you to view your customers' responses to the post booking questionnaire.
To view this report you will navigate to the Reports tab, and select the Report Templates option. After this you will scroll to the bottom of the Suggested Reports on the right side of the page and select the Questionnaire Report.
Here you can view your customers' questionnaire answers for each guest that has filled one out, and export it into a spreadsheet if needed.
You can also customize this view by deciding which columns to include, and filter the information in each customizable column. Click here for for more detail on Custom Report Templates.
