Question

I’m trying to open a word document and just extract all the text that is in the document and display it to the user using Win32::OLE

#usr/bin/perl
#OLEWord.pl

#Use string and print warnings
use strict;use warnings;
#Using OLE + OLE constants for Variants and OLE enumeration for Enumerations
use Win32::OLE;
use Win32::OLE::Const 'Microsoft Word';

$Win32::OLE::Warn = 3;

#set the file to be opened
my $file = '/work/Test.docx';

#Create a new instance of Win32::OLE for the Word application, die if could not open the application
my $MSWord = Win32::OLE->new('Word.Application','Quit') and "Opened Word" or die     "Unable to open document ", Win32::OLE->LastError(); 
#Set the screen to Visible, so that you can see what is going on
$MSWord->{'Visible'} = 1;
#open the request file or die and print warning message
my $Doc = $MSWord->Documents->Open('C:\work\Test.docx') or die "Could not open ", $file, " Error:", Win32::OLE->LastError();

#$MSWord->ActiveDocument->SaveAs({Filename => 'AlteredTest.docx', 
                            #FileFormat => wdFormatDocument});
                            
                            
sub ShowObjs {
my $obj = shift;
foreach (sort keys %$obj) {
print "Keys: $_ - $obj->{$_}\n"; }
 }

 my $paragraphs = $Doc->Paragraphs;
 ShowObjs($paragraphs);

 #  Get and print the Text inside the opened file
 my $paragraphs = $Doc->Paragraphs;
 my $txt = $Doc->Range->Text;
 print $txt;
                            
 $MSWord->ActiveDocument->Close;
 $MSWord->Quit;

I’m getting this error code:

OLE exception from "Microsoft Word":

Command Failed

Win32::OLE(0.1709) error ox800a1066
in METHOD/PROPERTYGET "Open" at OLEWord.pl line 20

Update: I can open up the Word application fine, it’s just when I try to open up the file that is the problem

Answer 1

I have few scripts to convert DOC to various output format using Win32::OLE. They usually start like this:

use Win32::OLE;
use Win32::OLE::Const 'Microsoft Word';
my $wr = Win32::OLE->new('Word.Application')
    or die "Failure - word. \n";

$wr->{DisplayAlerts} = wdAlertsNone;
$wr->{Visible} = 0;

my $Doc = $wr->Documents->Open({
    FileName           => $input_file_path,
    ConfirmConversions => 0,
    AddToRecentFiles   => 0,
    Revert             => 0,
    ReadOnly           => 1,
    OpenAndRepair      => 0,
}) or exit;

...

Please note that $input_file_path has to contain absolute path to your file. You can also enable Visible and DisplayAlerts to see any error Word might give you.

Edit: You can traverse paragraphs using in enumerator:

use Win32::OLE qw(in);

...

my $paragraphs = $Doc->Paragraphs;
for my $par (in $paragraphs) {
    print $par->Range->Text();
}

Or you can use Word’s own exporting method and save document as one of supported formats:

$Doc->SaveAs({
    FileName   => 'c:\\work\\Test.txt',
    FileFormat => wdFormatEncodedText,
});

The advantage of latter method is that formatting is retained if possible, which produces better results for bullets, numbering and such.
