Answer by jq170727 for Converting JSON to .csv

Here is a solution using jq

If the file filter.jq contains

  .[]| {first_name, second_name, all:.fixture_history.all[]}| [.first_name, .second_name, .all[]]| @csv

and data.json contains the sample data then the command

jq -M -r -f filter.jq data.json 

will produce the output (note only 10 rows shown here)
