How do I convert YAML to JSON?
Paste your YAML data into the input field and click "Convert to JSON". The tool instantly parses your YAML and outputs valid, formatted JSON. You can then copy the result or download it as a .json file.
Why would I convert YAML to JSON?
Common reasons include: using YAML config data with JSON-only APIs, importing Kubernetes or Docker Compose configs into tools that require JSON, debugging YAML syntax by viewing the equivalent JSON structure, or migrating configuration between formats.
Does this tool validate my YAML syntax?
Yes, the converter validates your YAML during parsing. If there are syntax errors like incorrect indentation, missing colons, or invalid characters, it will show a clear error message pointing to the issue.
Does it support multi-document YAML files?
Yes, if your YAML contains multiple documents separated by
---, the converter will parse the first document by default. For multi-document files, each document is converted separately.
Is my data secure when using this converter?
Absolutely. All conversion happens locally in your browser using JavaScript. Your data is never uploaded to any server. This means even sensitive configuration files with secrets or credentials can be safely converted.
