Hello denizens of the Hard and Software forum

I want to make a questionnaire using Word (can be anything else though to be honest) and once I get people's replies back (in the above format via email - so each response is its own file) I want to collate the data into a spreadsheet, such as Excel and preferrably automatically (so I don't have to spend days collating several hundred replies manually).

Is it possible to do that? The questionnaire I got currently uses the Word Forms functions (textbox, checkbox, drop down menu) which I can of course modify to make it fit.

Did a quick google search and the only thing I found that was more or less identical to my request (but more complicated) was from rentacoder and that isn't available publically and not free.

Any help and pointers apprecaited, even where else I should be asking this instead!
