Bug? - Export to Excel: date formatted as text

when exporting query results to Excel (2003+, .xlsx format), DATE and TIMESTAMP columns are not formatted as dates; instead, they are formatted as text.

Tested versions:

  • 18.1
  • 18.2

Steps to reproduce:

  1. Start up SQL Developer using the default settings
  2. Run some query on a table or view containing DATEs and TIMESTAMPs. For example, the ALL_OBJECTS data dictionary view:
    • select * from all_objects;
  3. Export query results to an Excel (2003+) .xlsx file
  4. Open the resulting file

Expected result:

  • CREATED and TIMESTAMP columns contain numbers formatted as dates. For example:
    • CREATED should contain 42746, formatted as a date (11-JAN-17)
    • TIMESTAMP should contain 42746.5327893519 formatted as a date (2017-01-11:12:47:13)

Actual result:

  • CREATED and TIMESTAMP columns contain text. For example:
    • CREATED = "11-JAN-17"
    • TIMESTAMP = "2017-01-11:12:47:13"
