I have one final question concerning spreadsheet::xlsx

I have been writing a price list updater and with help and alot of reading I have a pretty badass little script. Thank you to all

my next question should be reasonably simple. Of Course its the things that seem the most simple that I seem to struggle with.

Heres the script so you can see what I am talking about

#!/usr/bin/perl
use strict;
use Spreadsheet::XLSX;

my $excel = Spreadsheet::XLSX -> new ('build.xlsx');
my $sheet = $excel->Worksheet('Sheet1');
my ($row_min,$row_max) = $sheet->row_range();


my %colD=();
for my $row ($row_min..$row_max){
  my $valD = $sheet->{Cells}[$row][3]->{Val}; 
  $colD{$valD} = $row+1; # excel row number
}


open FILE,'>','feckyou.txt' or die $!;
for my $row (1..$row_max){
  my $valA = $sheet->{Cells}[$row][0]->{Val}; 
  # does this value exist in Col D
  if (exists $colD{$valA}) {
    my $valB = $sheet->{Cells}[$row][1]->{Val};
    my $xlrow = $row+1;
    print FILE "price change [A$xlrow]=[D$colD{$valA}] Value=$valB\n";
    
  }

  elsif (!exists $colD{$valA})  {
  open FILE2, '>','newproducts.txt' or die $!;
    my $valB = $sheet->{Cells}[$row][1]->{Val};
    print FILE2 "New Product: = $valA Price = $valB\n";
    close FILE2;
   }
  }

In the if statement above it takes any instance of a new product id in colA and looks for it in colD. if it finds it anywhere in ColD it puts it in a text file. I need it to take the price it finds in ColB, which is also currently printing to the text file. I need to print that value (the price in colB) to Column R in the corresponding row with column A.

So, if Column A6 has a product code of 12345 and the script finds a match all the way on Column D2341, it will write the price from Column B6 to Column R6.

I cannot find the syntax for writing back to an Excel spreadsheet using Spreadheet::xlsx

thank you
