Spreadsheet with a spell rotation ?
 

I have seen other classes such as shadow priests with spreadsheets were you could plug in your spec , set a priority for you spells and it would make you a spell rotation from that.

Any idea where one might find such a spreadsheet ?

Try reading the first page of this sub-section.

I looked over that and the search field with no luck.

I don't think you will find one, simply because the timers on DoTs lend themselves more to a "refresh as you can" order than something that you can plan out in a reliable cycle.

In general, no talent spec of warlock relies on a rotation. Keep all your dots up and nuke away until any of them needs refreshing. You have a rough dot priority order based on DPCT and refresh as things come up.

Cast rotations don't work for us because we have lifetap and dark pack to return mana at will (thus, DPM isn't a big deal) and few procs/gimmicks to take advantage of.

Also moving would screw up any spell rotation.
However I don't think it should be that hard to make an "estimated" spell rotation for the purpose of a spreadsheet. As long as it's close enough, in the long run, to what you'll cast in battle.

And even if you weren't moving, resists [0] will still screw things up. The closest thing you can get is a DPCT (damage per cast time) evaluation. Use the Leulier sheet for that.

[0] Still a 1% chance on each spell cast at hit cap.

They removed the innate 1% chance to be resisted by spells. The spell hit cap is now 17% (as opposed to 16% with a 1% chance to be resisted). Please check your facts.

You do realize he made that post a year ago, right? o_O

D'oh, I got owned by a necro! It was at the top of the forums when I checked, so someone posted and deleted QQ =(
