Convert between simple YAML and JSON.
YAML ↔ JSON converts simple flat YAML maps to JSON and back in your browser. It is built for quick key/value config snippets — names, flags, and scalars — not full multi-document YAML with anchors and deep nesting.
Many apps accept both YAML and JSON for the same settings. This tool helps you flip a flat map either way: YAML lines like key: value become a JSON object, and a flat JSON object becomes YAML lines again.
The YAML side is intentionally simple: one key per line, no nested indentation trees, no multi-document streams, and no anchors/aliases. Booleans (true/false) and numeric-looking values are coerced when converting YAML → JSON. Quoted strings strip surrounding quotes.
If you need full YAML 1.2 (nested maps, arrays, multiline blocks), use a proper parser in your stack (for example PyYAML, snakeyaml, or js-yaml). This page optimizes for the everyday “I have five settings and need the other format” case without uploading config files.

Select YAML → JSON or JSON → YAML depending on what you already have.
For YAML, use flat key: value lines. For JSON, paste a single object with scalar values.
Run convert, fix any parse errors, and copy the result into your config or PR description.
Translate a handful of environment-style settings between a JSON-based tool and a YAML-based deploy file.
Show the same sample configuration in both formats without retyping every key.
See how true/false and numbers are interpreted when moving from YAML text into JSON.

Quick answers about tools, privacy, limits, and pricing.
Not with this lightweight converter. Nested indentation, lists, and multi-document files need a full YAML library. Stick to flat maps here.
YAML → JSON coerces values that look numeric and recognizes true/false. Quote the value in YAML if you need to keep it as a string (depending on how you later re-export).
The reverse path expects a flat JSON object of scalar-friendly values. Nested structures will not round-trip cleanly through the simple line serializer.
No server round-trip is required for the conversion itself; it runs in your browser session.
Yes. YAML ↔ JSON is free to use on ezToolFlow. Guests and free accounts may have daily limits on some tools; premium tiers can raise or remove those limits. AI tools may also spend credits.
For browser-based tools, processing runs on your device when possible and files are not uploaded for conversion. Optional accounts, usage limits, and AI features are described in our Privacy Policy.
No for most tools — you can start as a guest. An account helps keep higher daily limits and saved work (for example AI resumes).
Close other heavy tabs, use a smaller input file, and try Chrome or Edge on desktop. Very large files can stress browser memory.
Yes, the page is responsive. Complex media or large PDFs still work better on desktop because of memory and CPU limits on phones.
YAML ↔ JSON runs in the browser so you can complete a task without installing apps. Desktop software may still be better for very large batch jobs or offline-only environments.
