Your data stays private
All conversion happens locally in your browser. Your JSON data is never uploaded to any server.
How to Use the JSON to YAML Converter
Enter Your JSON Data
Paste your JSON configuration or data into the input area, or upload a .json file. The converter accepts any valid JSON including objects, arrays, and nested structures.
Select Formatting Options
Choose your preferred indentation (2 or 4 spaces) for readability. Optionally enable flow style for compact inline output similar to JSON syntax.
Generate YAML Output
Click "Convert to YAML" to transform your JSON into human-readable YAML format. The conversion preserves all data structure and values accurately.

Copy the YAML output to your clipboard or download it as a .yaml file. Use it directly in Docker Compose, Kubernetes, Ansible, or CI/CD configurations.
Pro tip: Your data is processed entirely in your browser. Nothing is sent to any server, ensuring complete privacy.
How to Convert JSON to YAML
YAML (YAML Ain't Markup Language) has become the standard for configuration files due to its human-friendly syntax. Converting JSON to YAML makes your configuration files easier to read, edit, and maintain.
Step-by-Step Guide
- Paste your JSON data or upload a .json file
- Choose your preferred indentation (2 or 4 spaces)
- Optionally enable flow style for compact output
- Click "Convert to YAML" to process your data
- Copy the result or download as a .yaml file
Benefits of YAML
- Readable: Clean syntax without braces and brackets
- Comments: Add notes with # for documentation
- Multi-line strings: Better support for long text
- Standard: Used by Docker, Kubernetes, Ansible, and more
Common Use Cases
- Create Docker Compose files from JSON schemas
- Generate Kubernetes manifests from API responses
- Convert package.json data to YAML for documentation
- Create CI/CD pipeline configs (GitHub Actions, GitLab CI)
- Generate Ansible playbooks from JSON templates
Frequently Asked Questions
Why convert JSON to YAML?
YAML is more human-readable than JSON and supports comments. It's preferred for configuration files in Docker, Kubernetes, Ansible, and CI/CD pipelines where human editing is common.
What is flow style?
Flow style uses inline syntax like JSON ({key: value}, [1, 2, 3]) instead of YAML's indentation-based block style. It's more compact but less readable for complex structures.
Can I add comments to the output?
The converter produces valid YAML without comments. You can manually add comments (lines starting with #) after conversion, which is one advantage of YAML over JSON.
How are null values handled?
JSON null values are converted to YAML's null representation. In YAML, this can be written as null, Null, NULL, or ~ (tilde).
Will the YAML output work with Kubernetes/Docker?
Yes, the output is valid YAML 1.2 that works with all major tools including Kubernetes, Docker Compose, Ansible, GitHub Actions, and more.
