How do I lock hidden columns?

[Henk Neuhoff via OfficeKB.com]

How do I make absolutly certain that no one can unhide any hiddend coulmns in a worksheet? These columns are part of a price list and it is vital that no one can access it. I did protect the sheet and workbook, but I am still able to unhide the columns.

I am not an Excell expert so please explain in plain english!

Hi Henk

Try this in a blank new sheet:

Cell A1: You're the
Cell B1: silly
Cell C1: man !

Hide column B. You should read "You're the man !" , right ?
Now copy range A1:C1. Paste in another location.

Keep confidential information out of the file ! If it's in there then it's
accessible.

HTH. best wishes Harald

Thanks Harald

It worked the way you explained it, my problem is that there is formulas in the hidden columns, so if i hide, then copy them they can still be unhidden in the new sheet. I seem to copy the whole sheet!

Hi Henk

What you should do is physically delete everything that should not be seen.
If other cells' formulas are depending on the cells-to-be-deleted, replace
those formulas with values first. Trust me on this, you can not hide
information good enough in an excel file. Excel is not made for that.
