Yesterday Spreadsheet::ParseXLSX-0.13 has been released. This version now passes all tests that Spreadsheet::Read used for XLS (parsed by Spreadsheet::ParseExcel) and XLSX (previously parsed by Spreadsheet::XLSX).
Spreadsheet::Read-0.54 has just been released to prefer Spreadsheet::ParseXLSX over Spreadsheet::XLSX which opens up a whole lot of new features for XLSX. The old parser is still supported.
I specifically thank Jesse Luehrs for the quick feedback and fixes in the parser.
Enjoy, Have FUN! H.Merijn
