With a Datacloud username and password (paid version) you can run a sleuth profile and view the data.
Sleuth prevents duplicates of Accounts, Contacts and Lead in Salesforce.com as they are created and lists duplicates of existing Accounts which can be expanded with the use of
Pervasive DataProfiler.
Sleuth runs in Pervasive Datacloud and will scour all of your existing records in Salesforce and display all duplicates. You may, then, easily decide which 'alleged duplicates' you would like to merge together using Salesforce's built in merge tool.
When a duplicate record is created within an Account, Contact or Lead, Sleuth will take action by displaying a warning message on the duplicate with options to fix the duplicate through a rename or merge.

In addition, a notification is sent out via email to the account, contact, or lead owner to alert the user that a duplicate was created.
In order to run a sleuth profile the following steps are necessary:
- You must enter valid Salesforce.com username and Salesforce.com password
- Click Save Settings.
- Then Click Run Sleuth Profile
- Wait for the dialog box to say Finished.
- Click Ok
- Click the View Data button to view your duplicates. (next screen)
