Can I convert in both directions?

Yes. You can paste YAML and convert to JSON, or paste JSON and convert to YAML — the tool works bidirectionally with a single click.

Does it preserve comments?

YAML comments are not preserved when converting to JSON, as JSON does not support comments. However, all data values and structure are accurately converted.

Does it handle multi-document YAML?

The converter handles single-document YAML files. For multi-document YAML (files with --- separators), convert each document separately for best results.

What YAML features are supported?

The converter supports all standard YAML features including anchors, aliases, nested objects, arrays, multi-line strings, and all scalar types (strings, numbers, booleans, null).

Can I use this for Kubernetes configs?

Yes. This tool is perfect for converting Kubernetes YAML manifests to JSON format, which is useful for tools and scripts that require JSON input, and vice versa.

How does it handle YAML indentation errors?

YAML is indentation-sensitive. If your YAML has indentation errors, the converter will display a clear error message pointing to the problematic line so you can fix it.
