Set up Constraint in Xlsx

Hello.

 I would like to ask, if there is a possibility to set up constraint to not allow user to write more than three decimall places in cell? I preparing and sending file to user, and user is supposed to return file with some data. I would like to set up constraints on required field, to allow only good values.
Has anybody have any ide it this can be done? 

Have a Nice day
