What's the best way to format text to Proper Case in the Text driver?

For example, the data coming from a home-baked HR system is all UPPER
CASE. However, we have a certain field that is referenced by a list in
IDM UserApp, so therefore the data has to match, and we prefer it to be
Proper Case.

Right now we end up manually opening the file in Excel and using the:

formula to adjust it, save the file, etc.

For example:

needs to be:

needs to be:
Human Resources

Is there an xpath or something that can be called or whatever to
manipulate the data in the driver so that it gets written to eDir in
Proper Case?

The opinions expressed are my own.
