PLEASE save me 8,000 hours of manual work. I know one of you can figure this
out - I sure can't. Thanks for looking.
I don't know vba at all so if you want me to use it please be specific about
what to type where.

I have a million rows with data in column A that looks like this (including
the brackets):

<aaaaaa<bbbbbb
<cccccc111111111111
<ddddddddddddd

And I need column be to copy with additional text like this
<aaaaaa<write:(aaaaaa)<bbbbbb<write:(bbbbbb)
<cccccc<write:(cccccc)111111111111<write:1111111 11111
<ddddddddddddd<write:(ddddddddddddd)

Basically, for every string surrounded by <,
put the following in column B
copy the string surrounded by < but change the < to ()
add "<write:" in front of the string that starts with (
put a after the )

for any strings in column A with no < around it
copy the string and
add "write:" in front of it
put a after it

There can be more than on string with or without < in column A
If there is, everything in Column A needs to be in column B following the
rules above.
