Is there a form that can be installed on a Wordpress site that will send the information directly to an Excel or .csv spreadsheet? This is for information capture only; the data does not involve an email list at all?
no you actually need to save the data somewhere and then export it the way you prefer. You'd probably better not to use wordpress tables to save such data but inserting directly a mysql db, and then retrieve and output them in the format you need the data to be
