Take a look at RFC Tutorial - Deleting Excel Rows, Columns and Sheets. That said if you're driving excel via Win32::OLE you may be able to filter by the unique records. The text in bold is a hint, use this as the basis for a search.	[reply]

Open the spreadsheet with one of the Excel modules you can find in CPAN Read the values in the range into a hash as keys `$hash{'s_no/tags'}++` Iterate over hash keys and split them again like `perl -e '%hash = (q\|check1/init\|=>3,q\|check2/hi\|=>4); for(keys %hash){print join qq\|\n\|,split qq\|\/\|,$_};'` Celebrate Intellectual Diversity	[reply] [d/l] [select]
