Is there any easy way to convert [][] interface{} to [][]string ? What I want is to to write this [][] interface{} to a csv but writer in go accepts only [][]string. Additional info : my [][] interface{} contains 4 columns 2 of them are string and 2 are json.Number.
Thanks in advance.
Simplest way is probably to make new slices and write some loops:
var orig [][]interface{} var strs = make([][]string, len(orig)) for i := range orig { strs[i] = make([]string, len(orig[i])) for j := range orig[i]{ strs[i][j] = fmt.Sprint(orig[i][j]) } } 
var orig [][]interface should read var orig [][]interface{}.
interface{}, not to aninterface{}
