What do you guys use to calculate your trade metrics besides your broker?

I've manually exported my paper trades, now I would like to do some analysis on my trading, what do you guys use? At the moment, the data is sitting in a table in google sheets. I don't really want to manually match up my opening and closing trades in google sheets (There are about 400+ trades so far, and it's still growing..). If there's something which I can feed my trades into, and it automatically sorts and calculates the metrics, that'll be a great help.
