# Convert YAML to JSON

Parse YAML configurations into formatted JSON with real-time syntax validation and precise line-number error reporting.

## What is YAML to JSON converter?

YAML to JSON parses YAML — Kubernetes manifests, Docker Compose files, OpenAPI specs, CI configs — and outputs formatted JSON that APIs and JavaScript code can consume directly. Because YAML is indentation-sensitive, the converter doubles as a validator: a misplaced space or tab produces a clear error with the problem location instead of wrong data.

## How to use YAML to JSON converter

1. **Paste YAML** — Paste your YAML document or load the sample.
2. **Convert** — Click Convert to JSON to parse the YAML.
3. **Copy or save** — Copy the formatted JSON or save it as a file.

## Frequently asked questions

### Can this validate my YAML?

Yes. If the YAML has indentation or syntax errors, the parser reports them instead of producing JSON.

### Does it support multiple YAML documents separated by ---?

Convert one document at a time; split multi-document files at the --- separators first.

### Are YAML comments kept?

No. JSON has no comment syntax, so comments are dropped during conversion.
