I've run into similar problems to you.
Market sell orders in a citadel don't currently show up in CREST. Ranged buy orders *do* show up in CREST. There is no way to get a complete list of all Fortizars in game.
At the moment there are very few ways to get information about citadels:
1) Ranged buy orders show up in CREST, and if you use the individual item endpoint rather than the bulk region endpoint, you can find out the name of any citadel that has orders.
2) if you bookmark a citadel you can find out its system and type (but not reliably its name).
3) killmails where a citadel was involved reveal the owner of the citadel, and the system and coordinates where the person shot by the citadel died.
I know of no way to reliably find out:
* who owns a citadel (you could possibly sometimes infer this from killmails)
* the location of a citadel (you could possibly sometimes infer this from killmails)
* the services available at a citadel (you could infer the existence of the market if ranged buy orders exist at a citadel)
* docking rights
So basically your best bet is to scrape the CREST market orders endpoint for citadel names, and fly around lots of systems bookmarking citadels to catch ones that don't appear in CREST.
I've done this for my own purposes, and gone on to create an API for anybody that wants access to this information. Have a look at https://stop.hammerti.me.uk/api for more info about it. I haven't integrated this API with google docs/excel myself but it is possible to set them up to read JSON (which is what the API outputs). I'm planning to launch a crowd-sourcing effort in the next week or two to locate more missing citadels - the results of this will naturally be available via that API.
If you want to get ranged buy orders from Foritzars into a spreadsheet, then you can do that directly from CREST just as you would with orders at NPC stations. If you want to get sell orders in Fortizars into a spreadsheet then you will have to wait until CCP deliver further API support. However there hasn't been a lot of communication from them about this so its not clear how long things will take.
