I'm working with queries via the "SQL Developer." When I do get the results and would like to save them to an Excel file, I can't open the file with the .xlsx, or xls extension. My options given are .txt, the others, like .java, .class, .sql, I believe not useful for converting to xls.
While I can save a file that the Excel app opens, the format is not separated by rows, columns, and celles.
May be this is more of an Excel question?
