About the JSON ↔ YAML Converter

YAML is the config language of choice for Docker, Kubernetes and CI pipelines, while APIs speak JSON. This free JSON to YAML converter translates cleanly between the two, so you can move data from an API response into a config file or vice versa without hand-editing.

It runs in your browser and never uploads your data.

How to convert JSON to YAML (and back)

  • Paste JSON to get clean, correctly indented YAML.
  • Or paste YAML to parse it back into JSON.
  • Nested structures, arrays and multi-line strings are preserved.

Why convert between JSON and YAML

YAML is the config language of Docker Compose, Kubernetes, GitHub Actions and many CI systems, because it's easier for humans to read and edit than JSON. But APIs speak JSON. Converting between them lets you move data from an API response into a config file, or turn a hand-edited YAML config into JSON for a program to consume, without rewriting it by hand.

🔗 Embed this tool on your website — free

Copy this and paste it into your page's HTML. The tool runs in the visitor's browser, just like here. Change height to fit, or add the optional auto-resize snippet below. Add ?theme=dark to the URL for dark mode.

<iframe src="https://toolhq.dev/embed/json-to-yaml/" title="JSON ↔ YAML Converter — ToolsHub" width="100%" height="520" style="border:1px solid #e5e7eb;border-radius:12px;max-width:680px" loading="lazy"></iframe>
Optional: auto-resize the iframe height

Add this once on the same page so the iframe grows to fit the tool:

<script>
addEventListener("message", function (e) {
  if (e.data && e.data.type === "toolshub:resize") {
    document.querySelectorAll('iframe[src*="/embed/"]').forEach(function (f) {
      if (f.contentWindow === e.source) f.style.height = e.data.height + "px";
    });
  }
});
</script>
