Question 1

Does this YAML to JSON converter send my data to a server?

Accepted Answer

No. The entire conversion runs in your browser using JavaScript. Nothing you paste is transmitted anywhere. Safe to use with config files, secrets, or private infrastructure code.

Question 2

How do I convert YAML to JSON?

Accepted Answer

Paste your YAML into the input panel. The tool auto-detects it as YAML and converts it to JSON instantly. Click Copy to copy the JSON output.

Question 3

How do I convert JSON to YAML?

Accepted Answer

Paste your JSON into the input panel. The tool auto-detects it as JSON and converts it to YAML instantly. The output YAML is human-readable and properly indented.

Question 4

What YAML features are supported?

Accepted Answer

This tool supports YAML 1.2 including: strings, numbers, booleans, null, nested mappings, sequences, multi-line strings (block scalars), anchors and aliases, and comments (comments are stripped in the output). Binary and special YAML types not representable in JSON are shown as strings.

Question 5

Why does my YAML look different after conversion?

Accepted Answer

When converting YAML to JSON and back to YAML, comments are lost (JSON has no comment syntax) and formatting is normalized. Functionally the data is identical. Anchors and aliases are resolved and inlined in the output.
