Excel sheet validation

If a document is prepared in excel which requires password for openin or any changes,what should be ideally verified for validation of an this sheet ?
Is audit trail possible for excel?

Thanks in advance.

Have a read of this:


If it is merely a document that you have generated using excel that does not involve any routine calculations and you will print and archive then validation controls will not be applicable for you

Audit Trail is possible in excel but with some limitations, but those limitations can be overcome by adding additional controls in usage of the excel sheet

If you can clearly specify your requirement I can help you in suggesting validation requirements

Thanks for the reply.

The sheet is used only for updation and viewing the data.few columns and rows are protected for access.
No data is updated with any formula.
