See if this works:
1) Copy everything into Microsoft Word
2) Open "find and replace" and do the following replacements ("use wildcard characters" should be unchecked):
- replace (one space) with nothing
Then these have no spaces:
- replace $
with ^t
- replace /
with ^t
- replace y,
(with the comma) with ^t^t
- replace y
with ^t
- replace m
with nothing
Now paste this back in an Excel spreadsheet. You should have your data separated in cells like this: (empty), dollars, years, months, (empty), dollars, years, months, (empty), dollars, years, months...
So then you could just make a partial calculation every 3 cells =dollars*(years+(months/12))
and then sum these partials into one total.
Would this help?
