FAQ

What is YAML to JSON Converter?

YAML to JSON Converter transforms YAML documents into JSON format. Input: YAML text (supports YAML 1.2). Output: JSON object. Use case: Kubernetes configs, CI/CD pipelines, infrastructure as code.

What YAML features are supported?

Supports: maps, sequences, scalars, anchors (&), aliases (*), merge keys (<<). Does not support: custom tags, complex keys, multi-document streams (---). Comments: stripped in JSON output.

How are anchors and aliases handled?

Anchors (&name) and aliases (*name) resolved before conversion. Example: &defaults {a: 1} + *defaults → {"a": 1}. Circular references: not supported, returns error. Merge keys (<<): expanded inline.

Can I convert multi-document YAML?

No, single document only. Multi-document YAML (separated by ---): only first document converted. To convert all: split into separate files or use batch processing tools.

What about YAML-specific types?

YAML types converted to JSON equivalents. Dates: ISO string. Numbers: JSON number. Booleans: true/false. Null: null. Binary: base64 string. Custom tags: converted to string or error.

How to handle indentation errors?

Strict YAML parsing: indentation errors return line number. Common issues: tabs (use spaces), mixed indentation, trailing spaces. Fix: use YAML linter before conversion.

Is the output formatted?

Yes, pretty-printed JSON with 2-space indentation. Compact option: not available in basic version. To minify: use JSON minifier tool after conversion.

Can I convert back to YAML?

Yes, JSON to YAML converter available. Note: comments lost in JSON. Anchors/aliases: expanded, not preserved. Order: may change (JSON objects unordered).

Pro Tip

💡 Tip: For large files, consider compressing or splitting them first for faster processing. When batch processing, you can upload multiple files at once and the tool will process them automatically.
