YAML to JSON Converter
Paste YAML and instantly get clean, formatted JSON — anchors, arrays, multi-line strings, all handled correctly.
How to Use the YAML to JSON Converter
- Paste Your YAML — Copy YAML from a config file, CI pipeline, or Kubernetes manifest and paste it into the left textarea.
- Choose Indent Size — Select 2 or 4 spaces for the JSON output indentation.
- Click Convert to JSON — The parser processes the YAML and produces formatted JSON on the right.
- Review the Output — Verify the JSON structure — keys, arrays, booleans, and nested objects.
- Copy JSON — Click Copy JSON to use the output in your application or API.
Key Features
Anchor Resolution
YAML anchors (&) and aliases (*) are fully resolved — referenced values are inlined in the JSON output.
Multi-line Strings
YAML literal (|) and folded (>) block scalars are correctly converted to JSON strings with proper newline handling.
Type Inference
YAML booleans, nulls, integers, and floats are correctly mapped to their JSON equivalents — not treated as strings.
100% Private
All conversion runs in your browser. Your YAML config data is never sent to any server.
Side-by-Side
Input and output side by side for instant verification without switching between panels.
Config File Ready
Handles Kubernetes manifests, Docker Compose, GitHub Actions, and other common YAML config formats.
How YAML to JSON Conversion Works
YAML parsing is more complex than JSON parsing because YAML is a superset of JSON with additional syntax rules including significant whitespace, anchors, aliases, and multiple scalar styles. The converter implements a YAML parser that handles the most common YAML constructs used in config files.
YAML values like true, false, null, ~, integers, and floats are mapped to their JSON equivalents. YAML comments (#) are stripped since JSON doesn't support them. Dates (e.g., 2026-03-26) are treated as strings in JSON output.
Practical Examples
🇮🇳 Nitin Kulkarni, Nagpur — GitHub Actions Workflow
Nitin needed to convert a GitHub Actions YAML workflow to JSON to process it with a Python script that only accepted JSON. The converter handled the nested jobs, steps, and env keys correctly.
🇮🇳 Swati Reddy, Hyderabad — Kubernetes Deployment
Swati converted a Kubernetes deployment manifest YAML to JSON for import into a configuration management tool that required JSON. Anchors used for resource limits were resolved correctly in the output.
✔ K8s manifest converted🇯🇵 Yuki Tanaka, Tokyo — Docker Compose Migration
Yuki was migrating a Docker Compose setup to a platform that used JSON config files. The converter transformed the multi-service YAML into a clean JSON structure with arrays for ports and volumes.

YAML (YAML Ain't Markup Language) is a human-friendly data serialisation format. It uses indentation instead of brackets and braces, making it popular for configuration files. Kubernetes, Docker Compose, GitHub Actions, Ansible, and many CI/CD tools use YAML as their primary config format precisely because it's easy to write and read.
JSON, on the other hand, is the standard for data interchange between applications and APIs. When you need to process YAML configs with a JSON-based tool, pass YAML data to an API, or validate YAML structure in a JSON schema validator, converting to JSON is the most practical approach.

Is this tool free?
Yes, the YAML to JSON Converter on StoreDropship is completely free with no registration required.
What YAML features are supported?
The converter supports YAML mappings, sequences, scalars, multi-line strings, booleans, nulls, and numbers.
Are YAML anchors and aliases supported?
Yes, YAML anchors (&) and aliases (*) are resolved during conversion — the referenced values are inlined in the JSON output.
Is my YAML data sent to a server?
No. All conversion happens entirely in your browser. Your data never leaves your device.
What happens to YAML comments?
YAML comments (lines starting with #) are stripped during conversion as JSON does not support comments.
Can I convert Kubernetes or Docker Compose YAML?
Yes, the tool handles Kubernetes manifests and Docker Compose files — simply paste the YAML and convert.
What is the difference between YAML and JSON?
YAML uses indentation and is designed for human readability; JSON uses braces and brackets and is designed for machine parsing. YAML is a superset of JSON.
Does YAML support data types that JSON doesn't?
Yes — YAML supports dates, binary data, and complex anchors. Dates are converted to strings in JSON, and anchors are resolved inline.
