Several reputable engineering sources offer verified versions:

: Calculates the theoretical dimension over pins for both "actual" and "effective" tooth thickness, providing a "Verified" status only when these values stay within the DIN 5480-14 tolerance zones. din 5480 spline calculator excel verified

Because finding the inverse involute requires an iterative mathematical solution, you can either implement a simple VBA macro or use a high-precision numeric approximation directly within the cell block.
