If you install CE 6.5 elsewhere, you might be able to just copy the cbimport binary and use it. There was some talk about having a separate “tools only” download (which will be especially important as more people start to use Couchbase Cloud), but I haven’t seen that materialize yet.
If you mean with cbexport, then no I don’t think so. That operation would likely require a N1QL query and index, so cbexport would not be the right fit. You could use curl with the N1QL REST API. Another option that’s relatively new and experimental is the Couchbase Shell, which can also execute N1QL queries.
