Converting JSON to .csv

I've found some data that someone is downloading into a JSON file (I think! - I'm a newb!). The file contains data on nearly 600 football players.

Here's the file: https://raw.githubusercontent.com/llimllib/fantasypl_stats/f944410c21f90e7c5897cd60ecca5dc72b5ab619/data/players.1426687570.json

Is there a way I can grab some of the data and convert it to .csv? Specifically the 'Fixture History'?

Thanks in advance for any help :)
