I know this thread is a little bit old now, but I'd just thought I'd let you know I just released an addon for just specifically Alchemy.
You can choose what effects you want to have on a potion, and it spits out what combination of ingredients you need to get that kind of potion.
It works on hardcoded strings for the ingredients and what effects they have, so your whereabouts and alchemy level is irrelevant for this addon. Primary objective was to be able to answer guildies who want you to make specific potions and what they need to give you to be able to make it.

Then you also have
http://www.esoui.com/downloads/info405-PotionMaker.html which was released just hours before mine (curse my slow writing!) which does roughly the same, but gives you the possibilities of what you currently have in your bag, and from what I understand (haven't had the chance to actually try it), it only pops up at a crafting table.
Hope any of them help you with what you wanted without actually having the spreadsheet.
