Not sure whether this is something that I should be asking you to advise on so please don't hesitate to tell me to go forth and multiply!!!

Anyway, here goes. I have extracted a load of electricity consumption stats via API and produced a response that is json. The data consists of half-hourly timestamps in Unix format together with the usage. Eg [1646092800, 0.122], [1646094600, 0.089]

How should I proceed to enter this data into an Excel spreadsheet to show the timestamps in one column and the kWh in another? There are approximately 200 separate entries. I am able to do the timestamp conversion but I cannot see how to extract the json file's data into csv.
