I haven't found a good and simple solution to my problem:
I need either online shared excel file with password protected access or a shared online form like excel adding names+rows+person
related data.It has to be lockable on a specific date.
Google Sheets is too open and general. I have to be the admin and be able to lock the Sheet, if the deadline is past and the content in the forms should match.
Also, A simple doodle ak is not a desirable solution. Does Anyone know a product which provides such service? Or Do I have to write a quick web interface?
