How can I down load al the dataform records?

If you mean export to spreadsheet then In Dataform 2.1.1 this was done via export to portfolios and it was reported that it didn't work in Moodle 2.4 (CONTRIB-4180; https://moodle.org/mod/forum/discuss.php?d=216886&parent=967192).
You should be able to work around this reasonably well by using the spreadsheet Insert > Link to External Data... (Open Office Calc; there should be something similar for Excel).
See illustration below (Calc).
