Hi,
maybe this is outdated, but since i stumbled upon that little problem, i wanted to share my solution.
working with excel 2010 i found my solution in using a straight forward excel formula.
=WENN(ZÄHLENWENN(C$1;""&$B2&"");1;0)
in English i think it is:
=IF(CountIF(C$1;""&$B2&"");1;0)
given you have your respondents listed in columns (starting at column "C"), your answers/questions in lines:
for every possible option add one line and put the options text in column "B"
so you got this:
A B Resp1 Resp2 Resp3
question_x original b1 c1 a1 a1 n c1 b1
question_x a1 1 0 0
question_x b1 1 0 1
question_x c1 1 1 1
question_x n 1 0 0
put the formular in the cells for every option and respondent and you get 0 and 1 instead of multiple (part)strings.
please forgive my poor english, hope that may help
