Need way to import *new* connections to SQL Developer without manual typing. Is it possible to import them from a spreadsheet or csv?
If you go into SQL Developer, right click on "Connections" and you can export existing ones. I know that is not your question, but bear with me :-)
You will end up with an XML file, for example:
If you can replicate that format with your new connections, then you should be able to import it.
