Before we start discussing different techniques to manipulate substrings in Excel, let's just take a moment to define the term so that we can begin on the same page. High-Level Interface Example¶. In most languages, the code to calculate density Dof Nitrogen at a temperature Tof 298 K and a pressure Pof 101325 Pa is something like: rho=PropsSI('D','T',298.15,'P',101325,'Nitrogen') See more examples of PropsSI usage at High-Level interfaceor Examples. Help¶. The REFPROP Excel front-end is supplied as a Microsoft Visual Basic module.

The only caveat to this that the MATLAB interface is simply a Python wrapper.
