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::ParseExcelppm 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);
