I rather doubt that the one single macro is 31 pages long - although it might
just be.
An individual macro starts with
Sub macroName()
or
Private Sub macroName()
and the individual macro(s) end with
End Sub
There can be many macros in a single code module, or if someone is recording
macros from the keyboard, there may be only one macro per code module.
What might be best, if the information/workbook, is not of such a nature as
to make it one you don't want someone else to have access to, would be if you
could email me and attach the entire workbook to the email. That would let
me take a look at the code and if it branches out and makes calls to other
routines within the code, those portions would be available for examination
also. Email address is (remove spaces) HelpFrom @ jlathamsite.com
Hopefully your coder put some comments in the code to help decypher it -
while some things such as what you displayed here are self explanatory, often
comments help make the 'why' of a code segment more understandable.
No promises on a successful or complete translation/commenting, but I'm
willing to tackle pieces of it at least. 1500-200 lines of code is a lot to
deal with.
