Convert [][]interface to [][]string

Question

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.

@Adrian , isn't that backwards? OP wants to go __from__ an `interface{}`, not __to__ an `interface{}` — RayfenWindspear, Aug 07 '17 at 17:54

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])
   }
}

I think this is the only way to go :) – Mohammed Aug 07 '17 at 17:28
In the first line, `var orig [][]interface` should read `var orig [][]interface{}`. – sebastian Apr 26 '18 at 19:38
correct, thanks @sebastian – captncraig Apr 26 '18 at 20:19
