Cara Konversi JSON ke YAML dan Sebaliknya

Oleh Andi Putra Ogie · Update: Juni 2026 · 5 menit baca

Karena YAML adalah superset dari JSON, konversi JSON → YAML selalu aman dan tidak kehilangan informasi. Tapi konversi sebaliknya (YAML → JSON) perlu sedikit lebih hati-hati karena YAML mendukung fitur yang tidak ada representasinya langsung di JSON.

Contoh Konversi JSON → YAML

// JSON
{
  "nama": "Toko Maju",
  "produk": ["sepatu", "tas", "topi"],
  "alamat": { "kota": "Bandung" }
}

# YAML
nama: Toko Maju
produk:
  - sepatu
  - tas
  - topi
alamat:
  kota: Bandung

Hal yang Perlu Diperhatikan Saat Konversi YAML → JSON

Komentar akan hilang — JSON tidak punya sintaks komentar, jadi semua # di YAML akan dibuang.
Anchor & alias di-resolve — referensi &/* di YAML akan "diuraikan" jadi nilai penuh berulang di JSON.
Boolean implisit — pastikan yes/no/on/off di YAML benar-benar dimaksudkan sebagai boolean, bukan string, karena hasilnya akan berbeda di JSON.
Multi-dokumen YAML (dipisah ---) perlu dipecah dulu sebelum dikonversi, karena satu file JSON hanya bisa berisi satu struktur data root.

Cara Konversi Tercepat

Buka JSONYAMify.
Paste data JSON atau YAML kamu — tool otomatis mendeteksi format input.
Pilih format output yang diinginkan (JSON atau YAML) dan mode Compact/Pretty.
Salin atau download hasilnya.

💡 Konversi dilakukan 100% di browser kamu, jadi aman dipakai untuk data konfigurasi internal sekalipun — tidak ada yang terkirim ke server manapun.

How to Convert JSON to YAML and Back

By Andi Putra Ogie · Updated: June 2026 · 5 min read

Since YAML is a superset of JSON, converting JSON → YAML is always safe and lossless. Converting the other way (YAML → JSON), however, needs a bit more care since YAML supports features with no direct equivalent in JSON.

Example: JSON → YAML

// JSON
{
  "name": "Acme Store",
  "products": ["shoes", "bags", "hats"],
  "address": { "city": "Bandung" }
}

# YAML
name: Acme Store
products:
  - shoes
  - bags
  - hats
address:
  city: Bandung

Things to Watch When Converting YAML → JSON

Comments are lost — JSON has no comment syntax, so every # in YAML gets dropped.
Anchors & aliases get resolved — YAML's &/* references get expanded into full repeated values in JSON.
Implicit booleans — make sure yes/no/on/off in YAML are really meant as booleans and not strings, since the result differs in JSON.
Multi-document YAML (separated by ---) needs to be split first, since a single JSON file can only hold one root structure.

The Fastest Way to Convert

Open JSONYAMify.
Paste your JSON or YAML data — the tool auto-detects the input format.
Pick your desired output format (JSON or YAML) and Compact/Pretty mode.
Copy or download the result.

💡 Conversion happens 100% in your browser, so it's safe even for internal config data — nothing is sent to any server.
