      I have the below code which reads the column value. But the prb in the code is it prints each column value 3times. Could someone please help in finding the bug. The excel looks like below:
      perl flavors modules class Candidate Name vanilla excel first Nancy strawberry dumper second jimmy lettuce array third roma
      The perl code is as below:
      #use strict; use Spreadsheet::ParseExcel; my $FileName = "/home/dujnne/praice/excel/test.xls"; my $excel = Spreadsheet::ParseExcel::Workbook->Parse($FileName) or die + "Unable to open $FileName\n"; #locate columns in the spreadsheet from which we want to extract data my $found = 0; my ($rowCnt, $colCnt) = (0,0); foreach my $sheet (@{$excel->{Worksheet}}) { printf("Sheet: %s\n", $sheet->{Name}); $sheet->{MaxRow} ||= $sheet->{MinRow}; $rowCnt = $sheet->{MinRow}; foreach my $row ($sheet->{MinRow} .. $sheet->{MaxRow}) { $sheet->{MaxCol} ||= $sheet->{MinCol}; $colCnt = $sheet->{MinCol}; foreach my $col ($sheet->{MinCol} .. $sheet->{MaxCol}) { my $cell = $sheet->{Cells}[$row][$colCnt]; if ( lc $cell->{Val} eq "class" ) { $found = 1; print "OKAY: found the column as "class"\n"; print "INFO: searching for all classes \n"; $colCnt++; } if ( $found ) { print $sheet->{Cells}[$row][$colCnt]->{Val}, "\n"; next; } } } $found = 0; }

        Hello Pauler,

        I don’t really understand what this code is trying to do, so I’ll just offer some observations:

        1. The code as given does not compile. This line:

          print "OKAY: found the column as "class"\n";

          needs to be:

          print "OKAY: found the column as \"class\"\n";

          with the inner double-quote characters backslashed.

        2. You should always — yes, always! — begin each script with:

          use strict; use warnings;

          and never comment them out again!

        3. I suspect the script’s main problem is with the next statement on the 6th-last line. This ends the current iteration of the innermost loop, but as it’s the last statement within that loop, it currently does nothing. Perhaps you meant last? Or next LABEL; where LABEL refers back to a previous (i.e., outer) loop? See next and last in Perl documentation.

        Hope that helps,

        Athanasius <°(((><contra mundum
