Hi all, This is my first thread on perlmonks and i m feeling in a tricky situation with the task i need to solve it :) The task is: i have like 20 excel files, with same columns, but different data, and the columns are randomized in each file. What i need to do, is to join all the files into a "master" file, based on the column data from each file. For a quick solution i was thinking to map each column into a hash key and column data into an array of values for each column-hash, but i need to store these hashes somewhere until all the files are parsed. Any suggestion will be appreciate, Thanks
