YAML ↔ JSON Converter
Convert YAML to JSON and JSON to YAML online. Bidirectional conversion with validation.
YAML Input
Introduction
The YAML ↔ JSON Converter tool transforms data between YAML and JSON formats in both directions. It is ideal for working with configuration files, API definitions, and infrastructure-as-code templates across different ecosystems.
When to use this tool
Use this tool whenever you need to switch between YAML and JSON: migrating configs, adapting examples from documentation, or sharing data with teams that prefer a different format.
How to use
Choose conversion direction
Select whether you want to convert YAML to JSON or JSON to YAML based on your current source file.
Paste your source data
Paste valid YAML or JSON into the corresponding input area from your editor, terminal, or browser.
Run the conversion
Click the convert button to generate the target format with proper indentation and structure.
Copy or refine the result
Copy the converted data into your project, or tweak it further using other formatting and validation tools.
Examples
Converting Kubernetes manifests
Take a JSON-based manifest and convert it to YAML to match the style of the rest of your cluster configuration.
Adapting API examples from docs
When API documentation provides JSON examples but your tool expects YAML (or the other way around), convert them here instead of rewriting by hand.
