Go json array of arrays

Question

I've troubles with parsing json array of arrays using golang, all of them without names:

[[1594561500000, 1031.47571376], [1594562500000, 1031.43571376],[1595561500000, 1041.41376]]

Could you help me with it?

I suggest you read some introductory material on Go and its type system. — Burak Serdar

Don't forget to convert the string you use to hold the JSON to []byte first:

package main

import (
    "encoding/json"
    "fmt"
    "log"
)

func main() {
    s := []byte(`[[1594561500000, 1031.47571376], [1594562500000, 1031.43571376],[1595561500000, 1041.41376]]`)
    var nums [][]float64

    if err := json.Unmarshal(s, &nums); err != nil {
        log.Fatal(err)
    }

    fmt.Println(nums)
}

Try it on the Go Playground.
