YAML ↔ JSON Converter
Convert between YAML and JSON formats. Handles multiline strings, anchors, and flow syntax.
YAML ↔ JSON Converter
Convert between YAML and JSON formats bidirectionally with full YAML 1.2 support. The parser handles objects, arrays, multiline strings (literal and folded blocks), inline flow syntax, comments, anchors and aliases, multi-document streams, and special scalars like null, true, and numeric types. JSON-to-YAML output uses the most readable formatting at each level — block style for objects, flow style for short arrays. Useful for Kubernetes manifests, CI/CD configs, and infrastructure-as-code. Drop a .yaml, .yml, or .json file or paste content directly; copy the output to clipboard or download it as a file. Runs entirely in your browser — your data never leaves your machine.

YAML Is the Lingua Franca of DevOps
YAML is the default format for Kubernetes manifests, Helm charts, Docker Compose files, GitHub Actions and GitLab CI pipelines, Ansible playbooks, Terraform Cloud variables, and nearly every modern infrastructure-as-code tool. It is easier to read and edit by humans than JSON — no braces, no quoted keys, comments allowed — which is exactly why it wins in configuration use cases. But most APIs, CLIs, and programming libraries still prefer JSON, so converting between the two is a constant background task in DevOps work.
What This Converter Handles
This tool is a true YAML 1.2 parser, not a regex-based shortcut. It handles nested objects and arrays, literal (|) and folded (>) multi-line strings, inline flow syntax ([a, b, c] and {key: value}), anchors and aliases (&name / *name), comments, and YAML’s special scalar values (~, null, true, false, numeric types). JSON-to-YAML goes the other direction using the most readable formatting choice at each level. Paste a Kubernetes manifest, a GitHub Actions workflow, or a Helm values file and watch the structure clarify itself.
Cloud, CI/CD, and Configuration Management
For data-centric format conversion involving tabular structures, the XML ↔ JSON Converter handles document-oriented cases, and the JSON ↔ CSV Converter handles flat data. If you are migrating workloads to Kubernetes, standing up CI/CD pipelines, or building configuration-as-code around an existing platform, the YAML is the easy part. The hard part is deciding what belongs in code, what belongs in a secrets store, how environments diverge, and how deployments stay auditable. I build cloud infrastructure, CI/CD pipelines, and Linux-based platforms that keep configuration sane as systems grow.
