Best Way to Find USD Value of RVN on a Specific Date/Time?

Hey all,

I've been trying to put together a little spreadsheet of all of the mining deposits I had during last year but I need to be able to find out what the US dollar value of RVN was on the specific date and time for tax purposes. Does anyone know a good way to attain this information?

Better yet, if someone knows a way that I could use the exported data from Ravencore to pull all this information more easily I am all ears.

Thanks!
