This is an implementation of JSON to YAML converter written in Go language. This tool efficiently converts each JSON tokens in streaming fashion, so it avoids loading the entire JSON on the memory.

json2yaml file.json ...
json2yaml <file.json >output.yaml

You can combine with other command line tools.

gh api /orgs/github/repos | json2yaml | less

You can use the converter as a Go library. json2yaml.Convert(io.Writer, io.Reader) error is exported.

package main

import (
	"fmt"
	"log"
	"strings"

	"github.com/itchyny/json2yaml"
)

func main() {
	input := strings.NewReader(`{"Hello": "world!"}`)
	var output strings.Builder
	if err := json2yaml.Convert(&output, input); err != nil {
		log.Fatalln(err)
	}
	fmt.Print(output.String()) // outputs Hello: world!
}
