No type library matching "Microsoft Excel" found at D:\Genes_datase ts\exp.pl line 4

[CODE=perl]
use strict;
use Win32::OLE;
use Win32::OLE qw(in with);
use Win32::OLE::Con st 'Microsoft Excel';
# get already active Excel application or open new
my $Excel = Win32::OLE->GetActiveObjec t('Excel.Applic ation')|| die;

# storing the names of excel files present in the folder
my $dir="D:/Genes_datasets/";
opendir (DH, $dir) or die "cannot open the $dir !!!";
my @dir_files=read dir DH;
closedir DH;
my @excel_files=gr ep(/.xls/,@dir_files);
#print "@excel_files\n ";

# reading all excel files
foreach (@excel_files) {
open Excel file
my $excelfile=$dir .$_;
print "$excelfile \n";
my $book = $Excel->Workbooks->Open($excelfil e);
my $sheet= $book->Worksheets("Sh eet1");
$sheet->Activate();
my $rowval = $sheet->Range("a1")->{Value};

Unfortunately I don't have experience trying to read Excel files with Perl, but wonder if Excel should be installed for this to work? You may be correct in that assumption. If you can install it, it couldn't hurt to try it. If it works, let us know.

i don't ve microsoft excel but open office installed,

what is open office?

[numberwhun]

Open Office is the open source "equivelant " of M$ Office. It is available on a number of platforms and now comes standard with many Linux distributions. I use it exclusively on my Linux machines as it is able to easily read and write M$ Office files, at least I haven't had any issues.

Unfortunately, I wonder if he/she is correct that the module is looking for and calling something(s) from the Excel installation.

Seems obvious, if they don't have Excel installed they can't try and use it to process the file.

On the other hand, there appears to be a number of Open Office modules posted on cpan.

It is very obvious.

The Win32:OLE module allows your code to talk to any MS Windows OLE application that is available on the system from where you are running your code.

This clearly indicates that
* You must be running your code from an MS Windows machine
* You must have the OLE application (in this case Excel) setup on your machine


An easier solution would be to write the data in a comma seperated value (csv) format into a file with .csv extension and then open it in any spreadsheet program

Hope this helps

If you have installed excel, see if you are using a 64-bit version, if so, please add a win32 registry, the same content as win64.

Registry position: \HKEY_LOCAL_MAC HINE\SOFTWARE\C lasses\TypeLib\ {00020813-0000-0000-C000-000000000046}\1 .9\0\win32

It works! I also found the win32::ole error for my software after windows system upgrading. It seems the operation delete excel registry of Win32. With HaoRan‘s suggestion, I finally fix the glitch.
