perl读取excel

因为工作当中遇到要处理大数据的excel的玩意，最多的有几十万行。用perl的方式试试，看看效果如何。

ppm install OLE::Storage_Lite #如果不安装这个，后面两个安装不了
ppm install Spreadsheet::ParseExcel
ppm install Spreadsheet::WriteExcel

查看是否安装成功

perldoc Spreadsheet::ParseExcel #如果打印出文档则表示安装成功

为保证编码正确

ppm install Unicode::Map

use strict;
use Spreadsheet::ParseExcel;
use Spreadsheet::ParseExcel::FmtUnicode; #字符编码

my $parser = Spreadsheet::ParseExcel->new();
my $formatter = Spreadsheet::ParseExcel::FmtUnicode->new(Unicode_Map=>"CP936");#设置字符编码
#my $workbook = $parser->parse('Book.xls');
my $workbook = $parser->parse('E:\webdev\project\perl\a.xls', $formatter);#按所设置的字符编码解析

my $log = "demo.log";

if ( !defined $workbook ) {
    die $parser->error(), ".\n";
}

open(FILE,">$log");

for my $worksheet ( $workbook->worksheets() ) { 

    my ( $row_min, $row_max ) = $worksheet->row_range();
    my ( $col_min, $col_max ) = $worksheet->col_range(); 

    for my $row ( $row_min .. $row_max ) {
        for my $col ( $col_min .. $col_max ) { 

            my $cell = $worksheet->get_cell( $row, $col );
            next unless $cell;
            print $cell->value()," ";
            print(FILE $cell->value()."\t");
        }
        print "\n";
        print(FILE "\n");
    }
}

close(FILE);

记录下，明天去公司试试效果
