Hello all,
I work for a clinical research company. We are working toward
regulatory compliance with the FDA, and this includes electronic
records. At the current moment, we have system in place that exports
data to an excel spreadsheet from an old DOS based program. The
problem is that someone could theoretically change the data on the
spreadsheet, comprising the integrity and validity of the data and the
clinical trial. I need to make a system which does not allow users to
change the information on the spreadsheet.

I was thinking that a macro would work for something like this,
but I don't have much experience programming macros.

If anyone could point me in the right direction, I'd be grateful.

Thank you very much,
Mike
