Give a field in xls a specific text format, to use with xlsform

I need to specify the user to enter data in a specific format, in an excel spreadsheet.
I want to convert this spreadsheet into an xml, using xlsform.
Can someone please tell me how to give a text field a specific format in xlsform?
Thanks.
