Storing a Lot of Data

[Latrinsorm]

Hello!

So I need to store 20^7 pieces of data. Right now they look like two very long columns of:


5.5.5.5.95.85.5 3

I'm still procuring the data but it's become clear to me that an .xls or .txt file with the full set will have an unwieldy file size. Any recommendations? My end goal is to have Excel able to do a vlookup of the first value and return the second value but if there's another way, great.

I can't give you much in the way of actually practical advice, but this seems like you need to use a database for that quantity of data w/ fetch/lookup requests.
