How to export dict list to csv cleanly?

I have a script I’m writing to make pulling data from my fantasy football league easy and exported in a format that can be played with in Excel easily.

The script I have attached only contains the relevant parts to this questions as the larger script I have written has a lot of moving parts that doesn’t apply here.

I’m essentially pulling this players.get_all_players() data from the Sleeper platform using the Sleeper-API-Wrapper (Github link here).

My script will take player data and put it into a .csv like this, with the player ID in the top row and all the info in a single cell below the ID. Screenshot of this below.

How can I export this so that the data is nicely formatted into separate rows? I have a different spreadsheet where I’d like to be able to pull this data to automatically.

Alternatively, if I’m doing this in a really roundabout way, please let me know! This is the JSON response from the platform: JSON Response
