rj2y

This CLI tool is a simple utility to convert JSON to YAML. Especially useful when you want to convert JSON including JSON-embedded string.

{
  "iii": "{\"i\":\"{\\\"ii\\\": \\\"ii\\\"}\",\"ii\":\"ii\"}",
  "kkk": "{\"k\": \"{\\\"kk\\\": \\\"kk1\\\\nkk2\\\\nkk3\\\\n\\\"}\"}"
}

iii:
  i:
    ii: !!str ii
  ii: !!str ii
kkk:
  k:
    kk: !!str |-
      kk1
      kk2
      kk3

It may be convenient to reading server logs. Using with jq and yq is recommended.
