在Perl中读写Excel表

Perl中读写Excel很方便，贴段代码为以后参考。

读写Excel的组件需要另外安装，指令如下：

   perl -MCPAN -e shell -> install Spreadsheet::WriteExcel
   perl -MCPAN -e shell -> install Spreadsheet::ParseExcel

#!/usr/bin/perl
use Spreadsheet::WriteExcel; #写入Excel数据
use Spreadsheet::ParseExcel; #读取Excel资料

# 读取数据
# 使用: LoadStringsFromExcel(fileName);
sub LoadStringsFromExcel
{
	my $parser = Spreadsheet::ParseExcel->new();
	my $workbook = $parser->parse(@_[0]); #打开传入的文件
	my $TotalCount = 0;

	if(!defined $workbook) #是否打开成功
	{
		print "Failed to open @_[0]\n";
		die $parser->error(),".\n";
	}

	$Sheets_Count = $workbook->worksheet_count(); #有多少个Sheet

	#依次访问所有Sheet
	for ($index=1;$index<=$Sheets_Count;$index++) 
	{
		my $worksheet = $workbook->worksheet(@Sheets[$index-1]);
		my $result;
		if(!defined $worksheet) #读取Sheet失败
		{
			print "Could not get the worksheet \n";
			last;
		}
		else
		{
			$result = LoadWordingsFromSheet($worksheet);
			$TotalCount += $result;
		}
	}
	printf "\nTotal found $TotalCount strings\n";
	print "Finished!\n";
}

# 读取Sheet中字串，由LoadStringsFromExcel呼叫
sub LoadWordingsFromSheet
{
    my $sheet = $_[0]; #取得传入的sheet
    if(!defined $sheet)
    {
	   die "Could not get argument!\n";
    }
    
    #得到Sheet中的最小行号及最大行号
    my ($minRow,$maxRow) = $sheet->row_range();
    print "Now, checking ",$sheet->get_name()," \n"; #打印Sheet的名称

	$count = 1;
	
	#依次读取每行数据中第一列的数据
    for($i=$minRow;$i<=$maxRow;$i++) 
    {
		#取到第一列的数据, get_cell(行号，列号)
		$str = ($sheet->get_cell($i,0))->value(); 
		$str = trim($str);
		print $str,"\n";
		$count++;
    }
	return $count;
}


#写入Excel
#使用WriteDataToExcel(文件名)
sub WriteDataToExcel
{
	my $workbook = Spreadsheet::WriteExcel->new(@_[0]);#打开Excel文件
	if(!defined $workbook) #是否打开成功
	{
		print "Failed to open @_[0]\n";
		die $parser->error(),".\n";
	}
	
	my $worksheet = $workbook->add_worksheet(); #新建一个Sheet
	if(!defined $sheet)
    {
	   die "Cannot create new sheet!\n";
    }
	
	#写入第一行标题 write(行号，列号，内容)
	$worksheet->write(0,0,'ID');
	$worksheet->write(0,1,'RULE');
	
	#其它处理
}
