I have developed an extensive (macro-enabled) spreadsheet application that I
would like to share with others who do not have access to Excel. I would like
those users to be able to input into unprotected fields and be able to run
the macros; I have downloaded the Excel Viewer - but it does not allow for
user input or macros.

How can an Excel Spreadsheet be shared with others to be used as a
stand-alone application?

Thank you.
