Question

最初我尝试用Excel打开XML文件。但是，由于这需要很长时间，我将自己的XML解析为制表符分隔的文本文件。我以为我在互联网上找到了正确的语法。我使用我用Excel宏记录的值尝试下面的代码。我有一个18列制表符分隔文件。调用“工作表”方法时，在代码的最后一行出现错误。

错误讯息： 在./PostProcessingDev.pl第70行没有包或对象引用时，无法调用方法“工作表”。

use Win32::OLE;
use Win32::OLE::Const 'Microsoft Excel';
Win32::OLE->Option(Warn => 3);

use strict;

my $Excel;
my $Sheet;
my $Workbook;


$Excel = CreateObject OLE "Excel.Application";

$Workbook =  $Excel->Workbooks->OpenText({Filename =>"$inSelf->{'TXT'}",
  Origin => xlMSDOS,
  StartRow => 1,
  DataType => xlDelimited, 
  TextQualifier => xlDoubleQuote, 
  ConsecutiveDelimiter => "False", 
  Tab => "True",
  Semicolon => "False",
  Comma => "False",
  Space => "False",
  Other => "False",
  FieldInfo => [[1, xlTextFormat],
    [2, xlTextFormat],
    [3, xlTextFormat],
    [4, xlTextFormat],
    [5, xlTextFormat],
    [6, xlTextFormat],
    [7, xlTextFormat],
    [8, xlTextFormat],
    [9, xlTextFormat],
    [10, xlTextFormat],
    [11, xlTextFormat],
    [12, xlTextFormat],
    [13, xlTextFormat],
    [14, xlTextFormat],
    [15, xlTextFormat],
    [16, xlTextFormat],
    [17, xlTextFormat],
    [18, xlTextFormat]],
  TrailingMinusNumbers => "True"});

$Sheet = $Workbook->Worksheets(1);

Answer 1

你真的要用Excel解析TSV吗？如果您的文件中没有任何花哨的内容，您可能会使用以下内容：

my $file = 'some tsv file';
{
    open my $in,"<",$file  or die "$file: $!";
    while(<$in>) {
        chomp;
        my @cols = split /\t/;
        # do something with columns in @cols array
    }
}

如果由于我无法看到的原因需要Excel，则问题是OpenText方法返回True / False而不是Workbook对象。这有效：

use strict;

use Win32::OLE;
use Win32::OLE::Const 'Microsoft Excel';
use Data::Dump;     # for dd

Win32::OLE->Option(Warn => 3);

my $Excel = Win32::OLE->new("Excel.Application");
$Excel->Workbooks->OpenText({
    Filename             => 'enter the full path to file',
    Origin               => xlMSDOS,
    StartRow             => 1,
    DataType             => xlDelimited,
    TextQualifier        => xlDoubleQuote,
    Tab                  => "True",
    TrailingMinusNumbers => "True"
});

my $Sheet = $Excel->ActiveWorkbook->Worksheets(1);
my $Data = $Sheet->UsedRange()->{Value};

dd $Data;    # arrayref (rows) of arrayrefs (columns)

Answer 2

尝试使用Text::CSV。它支持用户定义的分隔符。请参阅模块说明。

感谢您的回答。这解决了我的问题。我想用OpenText方法做的就是将TSV文件转换为Excel，因为这是我需要的结果格式。在我想提供完整的代码之前，我无法在网上找到解决方案：

use Win32::OLE;
use Win32::OLE::Const 'Microsoft Excel';
use strict;

Win32::OLE->Option(Warn => 3);

my $FileName = "Complete Path of TSV File";

my $Excel = Win32::OLE->new("Excel.Application");

# Open Tab separated Text file in Excel, all 18 columns are "Text" formated
$Excel->Workbooks->OpenText({
  Filename      => $FileName,
  Origin        => xlMSDOS,
  StartRow      => 1,
  DataType      => xlDelimited,
  TextQualifier => xlDoubleQuote,
  Tab           => "True",
  FieldInfo     => [[1, xlTextFormat],
    [2, xlTextFormat],
    [3, xlTextFormat],
    [4, xlTextFormat],
    [5, xlTextFormat],
    [6, xlTextFormat],
    [7, xlTextFormat],
    [8, xlTextFormat],
    [9, xlTextFormat],
    [10, xlTextFormat],
    [11, xlTextFormat],
    [12, xlTextFormat],
    [13, xlTextFormat],
    [14, xlTextFormat],
    [15, xlTextFormat],
    [16, xlTextFormat],
    [17, xlTextFormat],
    [18, xlTextFormat]],
  TrailingMinusNumbers => "True"
});

my $Sheet = $Excel->ActiveWorkbook->Worksheets(1);
$Sheet->Activate;

my $Workbook = $Excel->ActiveWorkbook;

# Replace the "*.txt" file extension by "*.xls" for Excel
$FileName =~ s/txt$/xls/;

# Turn off the "This file already exists" message.
$Excel->{DisplayAlerts} = 0;
# Save file as Excel 2000-2003 Workbook (command for Excel 2007)
$Workbook->SaveAs({Filename => $FileName, FileFormat => xlExcel8});
$Excel->Quit;

如何使用Perl和OLE在Excel中打开制表符分隔的文本文件？
