Is there a vlookup formula to see if names of two clients (for example) resemble one another but may not be exact matches? for example may be company ABC LLC and company ABC, they match just minor differences.

There are algorithms for fuzzy string comparison.  You might apply one of these and determine at what level you consider the two strings 'similar'.

Our .Net user group had a coding contest a few months ago, to code up a Levenshtein comparison.

Note: near the end of the wiki article, there is a list of other fuzzy comparison algorithms.  You should look at those and decide which one is most suitable for you.

In a VLOOKUP, the last variable can be set to TRUE or FALSE.  FALSE returns only an exact match so you would want to set your last variable to TRUE.  Like this:

=VLOOKUP(D2, ClientInfo, 2, TRUE)

I've attached a document I create a while back on VLookups.  I hope you find it helpful
