I have made a few different google sheets for travian over the years. This first one is a collection of different calculators I have made when either bored or in need of something. I will suggest making copies of these sheets to your own drive before using them.
First sheet:

Description of the tabs:
NPC Calc - this is basically just a tool to NPC into troops. It is NOT needed much really. I usually use the one that is already included in the game, but this is can be useful if you have a heavy crop negative. If you have 2M res in your hammer and want 500k Wheat left, just put in 1.5M in the field for res.
Else it can show how much res you will need for queing.
XP/Scrolls - calculates if the changed hero XP is possible with scrolls. As you know, you might get a different XP if the srolls is taken one and one, instead of all together. The math here is not hard, but a nice calc if you can't be bothered to do it manually.
Trade route - this tab helps calculate how much res to send in each traderoute. You can add how long each celebration takes for you, then it tells you how much to send to have enough res stored for next celebration. By entering the time the mercs takes to the target village, it show you how many trips with return you can take in 24 hours. It also shows if you get more trips out of doing single routes or multiple deliveries for each route. Remember to set the number of trips you want yo take in a day to get the correct res of each type.
Travel time - Well, just a simple travel time calculator. Nothing special and there are lots of them out there.
Attack - This is used to time chiefing attacks from several villages. Put in the travel time for the different villages and and landing time for the one you sent first. This is also something you can do in getterplans, but this is a bit quicker and easier.
Second sheet:

This will help calculate travel time to all arts and show where they are on a map. It is all explained in the info tab in the sheet. This sheet has not been tested much, since I just made it. It will be sensitive to change in the source code for the arts in the TC. If some server is close to the arts now, give it a try
