YAML to JSON
Convert YAML configuration to JSON format
YAML Input
JSON Output
Turn YAML config into JSON your code can parse
Even if you write config in YAML, lots of tools — APIs, JavaScript runtimes, schema validators — only speak JSON. Converting YAML to JSON resolves anchors, expands aliases, and produces a clean object you can feed into validation libraries, request bodies, or app state.
Use the converter when you need to
Validate a YAML manifest with JSON Schema
Most schema validators accept JSON only — convert YAML to JSON first, then run validation.
Send a YAML config as an API request body
Many APIs accept JSON only. Convert your YAML payload before posting it.
Inspect a YAML file as structured data
Convert to JSON, then explore the structure in a viewer or feed it into JSONPath queries.
How to convert YAML to JSON quickly
- 1
Paste the YAML content into the editor.
- 2
Click Convert to produce JSON with anchors and aliases resolved.
- 3
Copy the JSON or feed it into a downstream tool.
Keep going
Convert JSON back to YAML
Round-trip the document when you need to write a YAML manifest or workflow file.
Validate the converted JSON
Catch any structural issues before the JSON hits an API or schema check.
Validate against a schema
Move from syntax to contract validation once the YAML is in JSON form.
Explore the result
Browse the converted JSON in tree view to confirm the structure looks right.
Common YAML-to-JSON workflows
Run schema and policy checks that only accept JSON without rewriting the YAML by hand.
Convert .github/workflows YAML to JSON to query the structure programmatically.
Convert YAML configs to JSON so you can compare them with structural diff tools.

Frequently Asked Questions
Paste your YAML content and click Convert. The tool parses YAML syntax including anchors, aliases, and multi-line strings, and outputs properly formatted JSON.
Many APIs only accept JSON. If you have a Kubernetes manifest, Docker Compose file, or CI/CD config in YAML and need to process it programmatically, converting to JSON makes it easy to use with any programming language.
Yes. YAML anchors (&) and aliases (*) are resolved during conversion, so the JSON output contains the fully expanded data without any references.
The tool processes the first YAML document in the input. If your file has multiple documents separated by ---, paste each one separately for conversion.
