In our company from time to time there are polls (like 'Name, Employee number, Will you attend the christmas party? Dinner preference?' ... ) which are typically handled via Excel sheets shared in a MS Sharepoint. The problem is that quite often one user or the other destroys the excel sheet, e.g. by sorting a single column, and in the end this workflow still causes a lot of work and trouble.
My question is if there is a safer way of letting people only edit one line in an excel sheet or automated gathering of information into excel sheets with standard tools which can be used in an intranet.
