How can I import data from Excel files using SQL Developer 4.2?
I have been following these instructions (from SQL Developer 4.1 New Features - Import Data Wizard), which used to work in SQL Developer 4.1.x but, apparently, SQL Developer 4.2 can only import from text files (delimited or CSV):
You have to pick your file first.
Where it says 'Data Import File' click 'browse.' Then pick your XLS or XLSX file.
