因為工作需要,給一些内容的結果需要轉換成excel給上面看,是以用perl來實作這個事件,發現perl來寫excel實在是太容易了。。我真想學老羅的講"太容易了,實在是太容易了". 在 2000 年,Takanori Kawai 和 John McNamara 編寫出了 Spreadsheet::WriteExcel 和 Spreadsheet::ParseExcel 子產品并将它們張貼在 CPAN 上,這兩個子產品使得在任何平台上從 Excel 檔案抽取資料成為可能。 perl寫excel這個子產品的内容 #!/usr/bin/perl

# 設定new一個對象出來,并寫上需要存成什麼名字的xls
my $xls = Spreadsheet::WriteExcel->new( "fukaiss.xls" );
# xml的内容名字
my $xlsContent = $xls->add_worksheet( 'report' );
# 這是對格式的設定,我們可以設定一個标題的,一個内容的,
# 我現在隻設定一個内容
my $contentStyle = $xls->add_format();
$contentStyle->set_size( 8 );
$contentStyle->set_bold(); #設定字型為粗體
$contentStyle->set_align( 'center' );#設定單元格居中
$contentStyle->set_text_wrap(); #是否回車換行
$contentStyle->set_color('red'); #設定單元格前景色為紅色
# 寫表内容(格式是使用上面添加的表格式)
# 這個中的A,B,C是設定的excel中上面行的字母
# 這個地方中的文字我用了decode這樣中文才能正常顯示
# 最後面的contentStyle是我上面設定的行風格
$xlsContent->write( "A1", decode( 'utf8', "名字" ), $contentStyle );
$xlsContent->write( "B1", decode( 'utf8', "時間" ), $contentStyle );
$xlsContent->write( "C2", decode( 'utf8', "語言" ), $contentStyle );
#$xlsContent->write($row, $col, 'Hi Excel!', $format); #行,列,内容,格式
#這是關閉,上面的内容設定成循環就能生成很多行了
$xls->close(); 其它一些有用的設定 # #設定列的寬度 set_column($first_col, $last_col, $width, $format, $hidden, $level, $collapsed) 下面perl是讀excel檔案内容 我用的Spreadsheet::Read 子產品可以讀取xls,csv和sxc等格式的檔案,這是那本Perl Hacks上非常推薦的讀這些的子產品. #!/usr/bin/perl
