Есть ли способ вложить данные в Google Sheets?

Question

Я работаю над проектом по преобразованию данных Google Sheet в API, но клиенту требуется вывод в следующем формате:

{  
   "BTC":{  
      "name":"bitcoin",
      "unified_cryptoasset_id" :"1",
      "can_withdraw":"true",
      "can_deposit":"true",
      "min_withdraw":"0.01",
      "max_withdraw ":"100" 
      "name":"bitcoin",
      "maker_fee":"0.01",
      "taker_fee":"0.01",
   }
```,

I am unable to understand how to Nest data under BTC ("BTC":{). There are many online resources available  to convert Google sheet into API but how I should structure data in Google Sheets that everything looks under "BTC". The format of output he needs I am unable to structure in Google Sheets.
