使用Spreadsheet :: ParseExcel時出錯

[英]Error when using Spreadsheet::ParseExcel

編譯以下代碼時出現2個錯誤:

#!/usr/bin/perl
use strict;
use warnings;

use Spreadsheet::ParseExcel;

my $xlsparser = Spreadsheet::ParseExcel->new();
my $xlsbook   = $parser->parse('xsl_test.xls');
my $xls       = $xls->worksheet(0);

my ( $row_first, $row_last ) = $xls->row_range();
my ( $col_first, $col_last ) = $xls->col_range();

my $csv = '';

for my $row ( $row_first .. $row_last ) {    #Step through each row
    for my $col ( $col_first .. $col_last ) {    #Step through each column
        my $cell = $xls->get_cell( $row, $col );    #Get the current cell

        next unless $cell;

        $csv .= $cell->unformatted();    #Get the cell's raw data -- no border colors or anything like that

        if ( $col == $col_last ) {
            $csv .= "\n";                #Make a new line at the end of the row
        } else {
            $csv .= ",";
        }
    }
}

錯誤:

global symbol "$parser" requires explicit package name at line 8
global symbol "$xls" requires explicit package name at line 9

我從http://www.ehow.com/how_7352636_convert-xls-csv-perl.html獲得了上述代碼,並使用以下代碼安裝了excel模塊: cpan Spreadsheet::ParseExcel Spreadsheet::XLSX Spreadsheet::Read

是什么導致錯誤?

這些錯誤表示您使用的是strict ,但是您並未在my腳本中聲明一些變量。 例如,您聲明了$xmlprser ,但是隨后嘗試使用未聲明的$parser 您復制的代碼有錯誤。

獲得代碼的更好的地方是源代碼本身: Spreadsheet :: ParseExcel

嘗試:

my $parser = Spreadsheet::ParseExcel->new();
my $xlsbook = $parser->parse('xsl_test.xls');
my $xls = $xlsbook->worksheet(0);

暫無
