YAML ↔ JSON Converter
Convert YAML to JSON or JSON to YAML instantly. Paste your input, see the result in real time, and copy or swap directions with one click.
When to use YAML vs JSON
YAML is preferred for configuration files — GitHub Actions, Kubernetes, Docker Compose — because it is human-readable. JSON is the standard for REST APIs.
What is preserved
All values, types (strings, numbers, booleans, nulls), nested objects, and arrays are preserved. YAML comments are dropped. Anchors and aliases are resolved.
Why use YAML ↔ JSON online?
YAML ↔ JSON in the browser saves context switching: no CLI install, no fragile one-liners, and instant feedback for teammates who do not live in the terminal. It is ideal for debugging, demos, and quick checks during code review.
Tips for best results
Work with a sample payload first, then paste production data. Keep privacy in mind: prefer local browser processing for secrets, tokens, and customer data. Bookmark this page for faster access next time.

Online tool vs terminal
| Terminal / CLI | This tool |
|---|---|
| Install CLI tools or write a one-off script | Open the tool in your browser — no install |
| Look up flags in man pages or Stack Overflow | Paste input or upload files where supported |
| Repeat for each file format or edge case | Get instant visual feedback and copy buttons |
Conversion runs in your browser using js-yaml — nothing is uploaded to any server.
Frequently Asked Questions
- What is the difference between YAML and JSON?
- Both represent structured data. JSON uses braces and quotes; YAML uses indentation. YAML is a superset of JSON. YAML is common in config files; JSON is standard for APIs.
- Does YAML to JSON conversion lose information?
- Comments are stripped. Anchors and aliases are resolved to their full values. All data values are preserved.
- Is this tool free to use?
- Yes. All Skybin developer tools are free with no account, API key, or usage limits.
- Does my data get sent to a server?
- No. Processing runs in your browser whenever possible. Sensitive input never leaves your device unless a tool explicitly fetches a URL you provide (e.g. OG Validator).
- Can I use this on mobile?
- Yes. The tools work in modern mobile browsers, though a desktop screen is easier for large JSON or PDF workflows.
- How is this different from desktop apps?
- There is nothing to install or update. Open a bookmarked URL and start working — ideal for quick tasks during development or support calls.
- Are there keyboard shortcuts?
- Most tools support standard paste (Ctrl+V / Cmd+V) and select-all in text areas. Copy buttons provide one-click output.
- Does Skybin store my history?
- No. We do not log tool inputs or outputs. Refreshing the page clears in-memory state unless the tool encodes state in the URL.
