Hi,
I've been reading a lot about Jfet's and biasing at ideal operating points. Although I am far from an expert I have created an Excel calculator that I thought might be helpfull to someone to aid in designing Jfet based preamps.
If anyone has suggestions for improvement feel free,
Cheers,

Looks really good.
Sheet 1 is Common Source.
Add a sheet for Source Follower (Common Drain)
Testing and measuring Vp & Idss could be on sheet 4 if you also have a Common Gate sheet.
Could you include cells showing the Formulae you have used?
For the Source Follower you could also add in the option to use the Dennis Feucht version with the extra resistors he adopts.
