Downloading Lots of CSV Data

I’ve had a project running for a while now, and when I tried to export CSV data, I got it for the past 12 days. Theoretically I should have a bit over a year’s worth of data, and it would be great to have the data from a year ago along with the 12 days I was able to download.

Is there any way to download data from a while ago, or is that not possible after a certain timeframe? Thanks
