  1. use strict;

  3. use Win32::OLE::Const 'Microsoft Excel';
  4. $Win32::OLE::Warn = 3;                                # die on errors...
  5. my $Excel = Win32::OLE->GetActiveObject('Excel.Application')

It has returned two dimensional array i.e an array with references to arrays.

so the value to be get from the array reference

If you want to output to a file, then you have to first open a file and get a file handle assigned, then use the file handle to point the print statement to the file for output.

Here is an example:

Expand|Select|Wrap|Line Numbers
  1. # open a file for writing to and assign a file handle
  2. open(FILE, ">file.txt");
  3.  
  4.  
  5. # Print out to the newly opened file
  6. print FILE ("Some text\n");

Change this block of code:

  1. open(FILE, ">file.txt");
  2.     foreach my $cell_ref (@$data) {
  3.           foreach my $value (@$cell_ref){

to:

  2.     foreach my $cell_ref (@$data) {

Hate to be redundant or insignificant in my response, yet here is my take.

Based on my limited understanding and personal roadblocks.

1) Reading/Looping Through an XLS file to extract data with perl is a $bear = killer koala

2) My path of least resistance to overcome said $bear, has been to require the XLS file to be converted (via save as) to a CSV format.

O.K -- I too am almost sick at the lame a$$ed effort to be cute with $variables

couldn't resist...

knowing enoughing to be dangerous and not much more

hutch

hi guys, i made some modification to my script above but quite puzzled again

well this time i got 2 sets of array
but i need to print them out in the same manner again like from excel it has:

1 4 DELETED
2 5 DELETED
3 6 DELETED

right the problem is the number are defined as cells from A1 to B3 as one array
and the deleted are taken from another cell say T1 to T3 in another array
so i got print out 2 arrays of info into text file in the manner:

1 4 DELETED
2 5 DELETED
3 6 DELETED

below is my code which i think is wrong when i tried to attempt to print the 2nd array out

ok i figured out found it somewhere
basically it's to print arrays into columns

so say @array1, @array2, @array3 into column
the below code works,
but can someone explain to me the principle behind this code how it works?

Expand|Select|Wrap|Line Numbers
  1.  
  2.             while(@array1 || @array2 || @array3) {
  3.                 printf FILE ("%-10s        %-10s        %-10s\n",
  4.                     shift(@array1) || '    ',
  5.                 shift(@array2) || '    ',
  6.                 shift(@array3) || '    ',
  7.     );
  8. }

  5.                 shift(@array2) || '    ',
  6.                 shift(@array3) || '    ',
  7.     );
  8. }    

The logic of this is code is like this:
- The code block in while loop as long as any of the three arrays exist i.e. if the arrays are of unequal size, the loop iterates until the last element in the largest array is processed.
- The printf() statement will format the output. In this case, a ten characters' space is left between the first characters of consecutive words.
- The three parameters to be printed are the elements of the 3 arrays.
- shift() statement keeps on removing the first element from the array. If any of the arrays is emptied, the shift() fails and the space character after OR(||) will be printed.
