Can Access use Fuzzy Logic

Here's the issue:

I have roughly 20 MS excel spreadsheets, each row contains a record.
These records were hand entered by people in call centers.

The problem is, there can and are duplicate phone numbers, and emails
and addresses even person names. I need to sift through all this data
(roughly 300,000+ records and use fuzzy logic to break it down, so that
i have only unique records.

Can I use Access or what to sort through all this data?
