Can anybody tell me whether it's possible to upload a fillable PDF and code the responses therein? Probably an unlikely capability, but as it would save my butt a lot of time and effort, I thought I'd ask the experts.
My thanks for any and all information you can provide.
I guess: No.
Hint: Stop searching and use the time to copy & paste the questions into LimeSurvey.
Or ask a LimeSurvey partner to set it up for you. It would safe time.
(If the PDF-creator software has the ability to export a xml-survey format there is a tiny chance.)
