Can someone help me convert a google spreadsheets file to a microsoft excel file?

https://docs.google.com/spreadsheets...it?usp=sharing This is the google spreadsheet i want to convert. I want to convert it because i want to try LOADS of combinations of permanent boosts, but it will take ages (One combo takes 10 seconds) So i want to use power pivot, but i need to convert this google spreadsheet to an excel file. But when i click the download as excel file in file drop-down, lots of the formulas get messed up. So i need someone to help me correct all of the formulas (someone else made this for me, so i dont get most of the formulas). Thanks!

I downloaded the file and had the same problem - all formulas converted to values. Selected the option to have it emailed to me, which has kept many, if not all, of the formulas. Unable to compress it to less than 1000 KB, so it exceeds the filesize limit. Try emailing it to yourself from the link you provided.

The whole of the "best expedition combination" sheet is still not working, be grateful if someone could fix it, you only need to fix a few formulas and then drag them to the rest of the cells to copy
