JSON to YAML Converter

工具介绍

Paste a JSON object or array and get clean, two-space indented YAML — ideal for Kubernetes manifests, GitHub Actions workflows, Ansible playbooks, and application configs. Conversion runs entirely in your browser.

工具概览

YAML is the de-facto config format for CI/CD pipelines and infrastructure-as-code because it is easier for humans to scan than JSON. This converter reads your JSON with the strict built-in parser, then emits YAML using plain-style scalars where safe and double-quoted strings when a value is ambiguous (looks like a number, boolean, or reserved keyword). Nested objects become block mappings, arrays become sequences, and empty collections collapse to `{}` or `[]`.

使用场景

• Turn API response fixtures into readable YAML for docs
• Rewrite JSON Kubernetes manifests as YAML
• Seed a GitHub Actions matrix from a JSON list
• Convert Postman/Insomnia exports for tooling that prefers YAML
