This is confusing, are:

use Spreadsheet::Read;
use Text::CSV_XS;

[download]

and

xlscat -S 1 -C 9-11,21  -c sample.xlsx >file1.csv

[download]

Different scripts? Why do you have use Text::CSV_XS;? Regardless you need to stop trying things at random in the hope they'll work. It's a poor strategy.

In order to perform the task you need to you do not need to write a script. Do the following steps, in order, don't do anything else:

1. Install Spreadsheet::Read, from the command prompt:

cpan Spreadsheet::Read

[download]

It will ask if you want to install xlscat as well as other utilities:

marto@shemp:~$ cpan Spreadsheet::Read

Do you want to install 'xlscat' (Convert Spreadsheet to plain text or 
+CSV) ?  [y] y
Do you want to install 'ss2tk' (Show a Spreadsheet in Perl/Tk) ?  [y] 
+y
Do you want to install 'xls2csv' (Wrapper around xlscat for easy XLS =

Checking if your kit is complete...
Looks good

cpan should install any prerequisites required.

2. run the commands Tux gave you here.

If you're actually interested in learning how these things work I suggest you spend time reading and understanding the following:
