I am trying to convert string to interface in golang but I’ve not found a solution for it yet. Can someone share with me your experience?

♦ Suggestions of ITtutoria Team
Idea for “convert string to interface in golang”: The string to interface function returns an interface that contains all the information about a field. This is what you use for converting a string into an object of your own custom types.

Here is our case study:

exInterface := data["exString"].([]interface{})
exString := make([]string, len(exInterface))
for i, ex := range exInterface {
    exString[i] = ex.(string)
}

  1. Here may be an example

    iAreaId := val.(int)
iAreaId, ok := val.(int) // Alt. non panicking version

  2. Here is the sample

    var myInt interface{}
myInt = 8
​
toInt, ok := myInt.(int)
fmt.Println(toInt, ok) // 8 true
​
toString, ok := myInt.(string)
fmt.Println(toString, ok) // "" false
