in reply to Error invoking Excel through cgi

Hi Raj. This is possibly Off-Topic, but here goes!

I was successfully able to serve up dynamic Excel files via the Apache Web Server to a web browser about a year ago. I went digging up through my file system and found this snippet. This is meant for a *NIX box, by the way - this might cause a problem when trying to write the temporary file on Win32 boxes.

use strict; use CGI qw(header); use POSIX; use Spreadsheet::WriteExcel; my $tmp_file = tmpnam(); { my $workbook = Spreadsheet::WriteExcel->new($tmp_file) or die; my $worksheet = $workbook->addworksheet() or die; my $format = $workbook->addformat() or die; $format->set_bold(); $format->set_color('red'); $format->set_align('center'); $worksheet->write(0, 0, "Hi Excel!"); $worksheet->write(1, 0, 1.2345); $worksheet->write(2, 0, "Hi Excel!", $format); } open(FH,$tmp_file) or die; print header(-type=>'application/'); print while <FH>; unlink $tmp_file;
If the user's Win32 box has Excel installed, Internet Explorer will use OLE to display the spreadsheet right in the browser. A catch is that the .cgi extension will confuse non-savvy users who don't know to save the file with a .xls extension instead. But ...

A really nice feature of the Apache web server is being able to specify your own extensions for CGI scripts. By adding this line to your <Directory> directive:

AddHandler cgi-script .xls
Now the Excel file can be saved 'as-is' without having to worry about getting the extension right.
