title: Golang decoding JSON into slice with one string and one float64
body: <p>I am running a query on a database that I have on a sever. The problem is when I am trying to decode the JSON into a 2D slice I get an error because one of them elements is a string and the other element is a float64. </p>
  
  <p>One way I tried to resolve this issue is my modifying the JSON string before I decode it by adding quotes to make the number a string. But is there a better way of doing this? Is there a way I can modify the struct of my code where I am able to decode the JSON code? </p>
