因为工作需要，给一些内容的结果需要转换成excel给上面看，所以用perl来实现这个事件，发现perl来写excel实在是太容易了。。我真想学老罗的讲"太容易了，实在是太容易了".
在 2000 年，Takanori Kawai 和 John McNamara 编写出了 Spreadsheet::WriteExcel 和 Spreadsheet::ParseExcel 模块并将它们张贴在 CPAN 上，这两个模块使得在任何平台上从 Excel 文件抽取数据成为可能。
perl写excel这个模块的内容
#!/usr/bin/perl
use strict;
use warnings;
?
use Encode;
use Spreadsheet::WriteExcel;
?
# 设置new一个对象出来，并写上需要存成什么名字的xls
my $xls = Spreadsheet::WriteExcel->new( "fukaiss.xls" );
?
# xml的内容名字
my $xlsContent = $xls->add_worksheet( 'report' );
?
# 这是对格式的设置，我们可以设置一个标题的，一个内容的，
# 我现在只设置一个内容
my $contentStyle?= $xls->add_format();
??? $contentStyle->set_size( 8 );
??? $contentStyle->set_bold();?????????? #设置字体为粗体
??? $contentStyle->set_align( 'center' );#设置单元格居中
??? $contentStyle->set_text_wrap();????? #是否回车换行
??? $contentStyle->set_color('red');???? #设置单元格前景色为红色
?
# 写表内容（格式是使用上面添加的表格式）
# 这个中的A,B,C是设置的excel中上面行的字母
# 这个地方中的文字我用了decode这样中文才能正常显示
# 最后面的contentStyle是我上面设置的行风格
?
$xlsContent->write( "A1",decode( 'utf8',"名字" ),$contentStyle );
$xlsContent->write( "B1","时间" ),$contentStyle );
$xlsContent->write( "C2","语言" ),$contentStyle );
#$xlsContent->write($row,$col,'Hi Excel!',$format); #行，列，内容，格式
?
#这是关闭，上面的内容设置成循环就能生成很多行了
$xls->close();
其它一些有用的设置
# #设置列的宽度
set_column($first_col,$last_col,$width,$format,$hidden,$level,$collapsed)
下面perl是读excel文件内容
我用的Spreadsheet::Read 模块可以读取xls,csv和sxc等格式的文件,这是那本Perl Hacks上非常推荐的读这些的模块.
#!/usr/bin/perl
use Spreadsheet::Read;
use Data::Dumper;
use Smart::Comments;
?
my $file = '2808861.xls';
my $spreadsheet = ReadData( $file) or die "Cannot read file ";#指定读的文件名
my $sheet_count = $spreadsheet->[0]{sheets} or die "No sheets in $file/n"; #这个是查有几个sheet
for my $sheet_index (1 .. $sheet_count){
??? my $sheet = $spreadsheet->[$sheet_index] or next;
??? printf("%s - %2d: [%-s] %3d Cols,%5d Rows/n",
???????????????????? $file,$sheet_index,$sheet->{label},$sheet->{maxcol},$sheet->{maxrow});#label是sheet名
??? for my $row (1 .. $sheet->{maxrow}) {
??????? print join "/t" => map {
??????????????????????????????? my $data = $sheet->{cell}[$_][$row] ;
??????????????????????????????? defined $data ? $data : "-";
??????????????? }1 .. $sheet->{maxcol};
??????? print "/n";
??? };
}
# 传一个输出的文件和一个数组和数组就能输入 execl?啦，记的第一行做标题
sub excelWrite(
??? my ( $filename,$file ) = @_;
??? my $xls = Spreadsheet::WriteExcel::Big->new( "$filename" );
??? $xls->compatibility_mode();
??? my $xlsContent= $xls->add_worksheet( "$filename" );
?
??? # 标题风格
??? my $titleStyle? = $xls->add_format(?
??????????????????????????????????????? size??? => 10,
??????????????????????????????????????? bold??? => 1,
??????????????????????????????????????? border? => 2,
??????????????????????????????????????? align?? => 'center',
??????????????????????????????????? );
??? # 内容风格
??? my $rowStyle??? = $xls->add_format(?
??????????????????????????????????????? align?? => 'left',
??????????????????????????????????????? border? => 1,
??????????????????????????????????? );
??? # 设置行的宽,先查出全部有数据的一行,来做为宽度的基准
??? my @tmp = ();
??? foreach my $line ( 2 .. $#{$file} ){
??????? foreach my $contentNu ( 0 .. $#{$file->[$line]} ){
?????????? next if $tmp[$contentNu];
?????????? $tmp[$contentNu] = $file->[$line][$contentNu];
??????? }
??? }
?
??? foreach ( 0 .. $#tmp ){
??????? $xlsContent->set_column( $_,$_+1,4 + length $tmp[$_]);
??? }
?
??? # 列
??? my $row = 0;
??? foreach my $line ( @{$file} ){
?
??????? # 对风格的处理,第一行不一样
??????? my $Style = $rowStyle;
??????? if ($row == 0 ){
??????????? $Style = $titleStyle;?
??????? }
?
??????? # 行处理
??????? my $col = 0;
??????? foreach my $content ( @{$line} ){
??????????? chomp $content;
??????????? $xlsContent->set_row($row,23);
??????????? $xlsContent->write( $row,decode("gbk",$content),$Style );?????
??????????? $col ++;
??????? }
?
??????? $row ++;
??? }
??? $xls->close();
}
