Yes. If you want to collect your stories using some other method (like SurveyMonkey or LimeSurvey or some other surveying method), you can import your stories into NarraFirma in CSV files. Look in NarraFirma’s help system for its “Guide to importing data.”
If you want to collect your stories using NarraFirma and export them to some other system (Tableau, R, a spreadsheet), you can export your data (on the “Export stories or story forms” page) in CSV format.
