How do I convert YAML to JSON?

Paste your YAML content and click Convert. The tool parses YAML syntax including anchors, aliases, and multi-line strings, and outputs properly formatted JSON.

Why would I need to convert YAML to 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.

Does the converter handle YAML anchors and aliases?

Yes. YAML anchors (&) and aliases (*) are resolved during conversion, so the JSON output contains the fully expanded data without any references.

Can I convert multi-document YAML?

The tool processes the first YAML document in the input. If your file has multiple documents separated by ---, paste each one separately for conversion.

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.
