It would be great if there was a cleansing action that would cleanse credit card numbers. It would alter all credit card numbers to be things like SQL Data Generator would generate (i.e. they would look like credit card numbers: they'd have the right length, they'd pass the Luhn algorithm check, etc)

In the Find and Replace cleansing action the replacement text is just static text, i.e. it can't be a regular expression. It'd be great if I could put things like "[0-9]{3}-[0-9]{2}-[0-9]{4}" and Data Cleanser would then generate a random string that matches the regular expression as the replacement text (just like SQL Data Generator would do).

For Data Protection and sanitising data for Test & Dev environments an easy means of removing identity info such as Firstname, LastName, Address, Phone, EMail,

Covered by others but a means of applying a data generating algorithm would make the tool invaluable to me.

The ability to replace a NULL with an empty string, zero, etc depending on the column data-type.

Add support for SQL Server 2012.

Wouldn't it be nice to have a simple UI for this component? Just like how other components have the Windows UI.

Seperate Leading and trailing white space as two different check-box options.

It's the cleaniest thing I've ever seen. Could you, however, clean data in situ?

this would be much more betterer

The titles in the three work areas of the tool take up a bit too much room. Please shrink them to maximise work area.

I also noticed you can alter the vertical parition, but not the horizontal one. make both adjustable.
