Had time this weekend, to "meditate" on it... The implementation was without external module, but with a "big" - hash of arrays, that i parsed it later on... It was in a way funny in the end, because i forgot to set the IFS to \r\n, reading from win files :) but finally thought of it... Any way i found a nice module: Spreadsheet::ExcelHashTable that is parsing the excel files straight into the hash... Thanks to all! Proud to be a part of this community.
