>You work too hard.<<br> ... and ...
why do you carry such a voluminous library of things exceptionally odd. Just select the applicable utilities. Looking at your original work sheet, one may wonder if Mathcad is at the age of the 0's 1's even before the age of computers. Why do you need an Excel data ? For checking and traceability, an image of the page of the applicable standard is needed (51 rows fit in one page) ... on that image, insert a red line that you can slide up/down and check all the searches from the little program.
What I'm saying: keep your work sheet minimal and modular.
