Most of the time in NAV you would just use a config package to export the data.
Note that a lot of tables and fields changed between C/AL and AL, so anything that you want to import will likely need to be re-formatted manually to the new layout before importing.
If you want to use a copy of the NAV equivalent tool, here is a copy of our Universal Export tool (one is for NAV2009 and older, other is NAV2013+).
This link will expire after this week. The file will still need to be compiled and licensed by your NAV partner before you can use it.
