It all depends what you want to do :)
There is a quick and painless way to export/import AD objects or modify them in bulk, and it is called the ADModify tool. You can get it here:
ftp://ftp.microsoft.com/PSS/Tools/Exchange%20Support%20Tools/ADModify/
ADModify is a GUI wrapper around LDIFDE. LDIFDE is the tool that can be used to export/import pretty much any AD object (some attributes can not be modified by it though, but some you can not modify even in ADSIEdit), and it allows modifications. That is as
opposed to CSVDE which does not allow modifications to existing objects.
So - ADModify might be a very easy answer here, depending on what is being exported. If more attributes are needed, then LDIFDE is the tool of choice. Run LDIFDE /? on the Command Line to see the options... it is not very pretty, and will take some trial and
error, but it should work.
