How It Works

1

Select Direction

Choose JSON to YAML for manifests or YAML to JSON for data processing. Paste your data and the tool will validate the syntax instantly.

2

Recursive Mapping

Our engine recursively maps data structures, ensuring that nested objects, arrays, and primitive types are correctly translated across formats.

3

Formatted Output

The result is pretty-printed with your chosen indentation size, making it ready for use in configuration files or documentation.

Common Use Cases

Cloud Infrastructure Manifests

Convert JSON-based cloud metadata into YAML formats required for Kubernetes (K8s) resources or Docker Compose files.

DevOps & CI/CD Pipelines

Shift configuration data between formats for tools like GitHub Actions, GitLab CI, or CircleCI which rely heavily on YAML.

Configuration Refactoring

Move application settings between JSON and YAML formats to suit different development environments or framework requirements.

100% Private & Secure

All processing happens directly in your browser. Your data never leaves your device — we don't upload, store, or have access to any of your content.

Instant & Offline-Ready

No server roundtrips means instant results. Once this page is loaded, the tool works even without an internet connection.

Frequently Asked Questions

Wait, isn't JSON technically YAML?

Yes, JSON is a formal subset of YAML 1.2. However, YAML offers a much cleaner, human-readable 'block style' that omits braces and quotes, which is what this tool focuses on.

How are null values and booleans handled?

The converter accurately maps JSON 'null' to YAML '~' or 'null' and preserves boolean true/false values to maintain data integrity.

Is my configuration data private?

Absolutely. All conversion logic runs locally in your browser session. Your configuration keys and sensitive values never touch our servers.
