Further to Anonymonk's point:
Do you see how the expressions $sheet->{F29} and $sheet{G30} access two completely different structures, one of which is empty? ... I can make no sense of the order in which it displays contents. A hash has no internal "order" except for the pairing of each unique key with its value. Access to and listing of hash keys, values and key/value pairs is (apparently) random. (Update: Don't be mislead by the fact that the order in the dump displayed above matches the order of initialization of the hash reference example: this is entirely adventitious. The dump of a larger hash structure will show greater disorder — but again, a key always cleaves to its value.) In reply to Re^10: Iterating Through Cell Blocks with Spreadsheet::Read
