I need to parse json into a struct in golang and the final value is a float64

But it seems that some inputs encode it as a string and some encode it as a float64

This is across a lot of variables so I would rather not make a custom function for each field

What is the best way to do this in golang?

I know the json tags can let values be stored as strings, but now that I am receiving raw floats it is starting to error out

This is a parsing FROM json only operation, so I do not care about what it implies or makes impossible for encoding TO json

Example code:

type Example struct {
  var1  float64 `json:"var1"`
}

func main() {
  var ex Example
  json.Unmarshal([]byte("{"var1":10.0}", &ex)
  json.Unmarshal([]byte("{"var1":"10.0"}", &ex)
}
