Hi joelnackman,

If you read the documentation for write_row, you'll see that it generates the same return code as write, which is:

    0 for success.
   -1 for insufficient number of arguments.
   -2 for row or column out of bounds.
   -3 for string too long.

So I believe you are incorrectly exiting with your code:

$worksheet->write_row($excelRow, 0, \@personData) or die "Write failed
+: $!\n";

That is to say, try changing or to and in the above line, and that section of your code should work.  You don't need to check the value of "$!", because it's not a system call, which may thus be giving you misleading results.

When I ran it, after "doctoring" the @personData array to hold some valid values, I was getting the error Write Failed: Bad file descriptor, which is a red herring.  When the logic was changed to interpret zero as success (and I added a line workbook->close() immediately afterwords), the Excel spreadsheet correctly contained the data I had written.
