Oracle introduced password protection for Excel 2007 outputs in its 18c update, allowing reports generated in BI Publisher to be password protected when downloaded as Excel files. Previously, password protection was only available for PDF outputs and there were bugs limiting its use for Excel. To enable it, users navigate to Reports and Analytics in BI Publisher, open a catalog, select a report, set a password, save the report, and run it. When downloading the Excel output, a prompt will appear requiring the password set at the report level. Dynamic passwords using SQL queries are not yet supported for Excel like they are for password protected PDFs.
