Thanks Bob - I have got XVI32 and this has some scripting capabilities but
there would be a bit of a learning curve.

Get a hex editor. There are plenty of free ones out there, search Google.

Is there a way of making hexidecimal changes to files using VBA in excel?

I have a large number of files that require a small change making to them
and this would speed it up.
