Hi John,

Glad to hear from you!
I tried with 0.46 version of XLSX module.. But after setting the tmp dir in this way,

workbook->set_tempdir('/opt/apache/secure-htdocs/exceldir/');
[download]

I still see this error,

Couldn't create sub directory /opt/apache/secure-htdocs/exceldir/CQ2RN
+O0V36/xl/worksheets: Permission denied at /opt/perl-5.8.3/lib/site_pe
+rl/5.8.3/Excel/Writer/XLSX/Workbook.pm line 809
[download]

I've given 777 permissions to the exceldir folder with ownership belonging to the web user..
