YAML to JSON Converter

工具介绍

Paste YAML and get structured JSON back. Handy for debugging CI configs, feeding YAML into a tool that only speaks JSON, or just inspecting what your config actually resolves to.

工具概览

The converter tokenizes your YAML line by line, tracks indentation to build the hierarchy, and resolves scalars to their JSON-native types (numbers, booleans, null, strings). Both block style (indented) and flow style ([a, b] / {k: v}) mappings and sequences are supported, along with comments, single- and double-quoted strings, and the usual `null`/`~`/`true`/`false` aliases.

使用场景

• Inspect a Kubernetes manifest as JSON
• Pipe a YAML config into jq or a JSON Schema validator
• Convert Docker Compose files for tools that require JSON
• Debug why a CI config is being parsed a certain way
