YAML to JSON & JSON to YAML Converter

Convert YAML to JSON and JSON to YAML in either direction with the YAML / JSON Converter. Paste your content, pass a whole list, or fetch it from a URL — the converter auto-detects the format, handles multi-document YAML, and gives you clean, indented output. Download each conversion as a ready file or as inline data in JSON, CSV or Excel.

Perfect for config files, CI/CD pipelines, Kubernetes and Docker Compose manifests, OpenAPI/Swagger specs and data-pipeline glue in n8n, Make and Zapier, it moves between the two most common config formats with zero code.

What it does

• 🔄 Both directions — YAML → JSON and JSON → YAML.
• 🧭 Auto-detect — figures out whether your input is YAML or JSON and converts the other way.
• 📄 Multi-document YAML — handles --- separated documents and returns them as an array.
• ✨ Clean output — pretty-printed JSON and tidy, readable YAML.
• 📚 Batch & URL — convert one document, a list of documents, or fetch a document from a URL.
• 📎 File + inline output — each result is saved as a downloadable file and (when small) included inline in the dataset.
• 📤 Export anywhere — JSON, CSV or Excel, or wire the output field into the next step of an automation.

Example

YAML in

name: my-app
version: 1.2.0
ports:
  - 8080
  - 9090

JSON out

{ "name": "my-app", "version": "1.2.0", "ports": [8080, 9090] }

How to use it

1. Paste your content (or add a list, or a URL to fetch).
2. Choose a direction — Auto, YAML → JSON, or JSON → YAML.
3. Optionally toggle pretty-print for JSON.
4. Run, and download the converted file or read it from the results.

Popular use cases

• Config conversion — move between YAML and JSON config formats instantly.
• Kubernetes & Docker — turn manifests and Compose files into JSON for tooling, and back.
• OpenAPI / Swagger — convert API specs between YAML and JSON.
• CI/CD — adapt pipeline definitions to whatever a tool expects.
• Automation glue — a conversion step inside an n8n, Make or Zapier workflow.

FAQ

Do I need an account or key? No. Paste your content and run.

Does it support multi-document YAML? Yes — YAML files with multiple --- documents are parsed and returned together as an array.

Can I convert many documents at once? Yes — add a list of documents and each is converted independently, with its own downloadable file.

Where does the converted file go? Each conversion is saved to the run's storage with a direct download link in the results; small results are also included inline.

Can I export to Excel or Google Sheets? Yes — the results table downloads as JSON, CSV or Excel and integrates with Sheets and automation tools.
