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", decode( 'utf8', "时间" ), $contentStyle ); $xlsContent->write( "C2", decode( 'utf8', "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, $col, decode("gbk",$content) ,$Style ); $col ++; } $row ++; } $xls->close(); }   *********将现有的excel文件导入到新的excel文件中实例********* import.pl #!/usr/bin/perl -w use strict; use Spreadsheet::ParseExcel; use Spreadsheet::WriteExcel; use Data::Dumper; # cobbled together from examples for the Spreadsheet::ParseExcel and # Spreadsheet::WriteExcel modules my $sourcename = shift @ARGV; my $destname = shift @ARGV or die "invocation: $0 <source file> <destination file>"; my $source_excel = new Spreadsheet::ParseExcel; my $source_book = $source_excel->Parse($sourcename) or die "Could not open source Excel file $sourcename: $!"; my $storage_book; foreach my $source_sheet_number (0 .. $source_book->{SheetCount}-1) { my $source_sheet = $source_book->{Worksheet}[$source_sheet_number]; print "--------- SHEET:", $source_sheet->{Name}, "\n"; # sanity checking on the source file: rows and columns should be sensible next unless defined $source_sheet->{MaxRow}; next unless $source_sheet->{MinRow} <= $source_sheet->{MaxRow}; next unless defined $source_sheet->{MaxCol}; next unless $source_sheet->{MinCol} <= $source_sheet->{MaxCol}; foreach my $row_index ($source_sheet->{MinRow} .. $source_sheet->{MaxRow}) { foreach my $col_index ($source_sheet->{MinCol} .. $source_sheet->{MaxCol}) { my $source_cell = $source_sheet->{Cells}[$row_index][$col_index]; if ($source_cell) { print "( $row_index , $col_index ) =>", $source_cell->Value, "\n"; if ($source_cell->{Type} eq 'Numeric') { $storage_book->{$source_sheet->{Name}}->{$row_index}->{$col_index} = $source_cell->Value*2; } else { $storage_book->{$source_sheet->{Name}}->{$row_index}->{$col_index} = $source_cell->Value; } # end of if/else } # end of source_cell check } # foreach col_index } # foreach row_index } # foreach source_sheet_number print "Perl recognized the following data (sheet/row/column order):\n"; print Dumper $storage_book; my $dest_book = Spreadsheet::WriteExcel->new("$destname") or die "Could not create a new Excel file in $destname: $!"; print "\n\nSaving recognized data in $destname..."; foreach my $sheet (keys %$storage_book) { my $dest_sheet = $dest_book->addworksheet($sheet); foreach my $row (keys %{$storage_book->{$sheet}}) { foreach my $col (keys %{$storage_book->{$sheet}->{$row}}) { $dest_sheet->write($row, $col, $storage_book->{$sheet}->{$row}->{$col}); } # foreach column } # foreach row } # foreach sheet $dest_book->close(); print "done!\n"; #import.pl source.xls des.xls
