LimeSurvey questionnaires can now be exported to Excel or other spreadsheet software tools (by going to Display/Export → Tab-separated-values format (*.txt) → Export), fully edited offline and then imported back to LimeSurvey (Create Survey → Import → Select survey structure file (*.lss, *.txt) or survey archive (*.lsa) → Import survey).
Download now a spreadsheet example of an entire LimeSurvey questionnaire structure that is ready to be imported into LimeSurvey and can be sent to respondents immediately. Feel free to check it out, there is more documentation on this topic in our manual.
