THANKS! It is a multi-sheet file it that will be an issue... will check it out post haste!
Windows download 1.10.11 version:

Gnumeric is an excellent spreadsheet. It uses an XML format and saves in a XML type file. It will import Excel directly and has a very flexible .txt file importer.
One of the most unusual features is the ability to do “Find & Replace” using Regular Expressions. To my knowledge it is the only spreadsheet that will do that. I have used it for years and although some jobs are easier in Excel it has some features that are unique.
