About DotYAML

A small, focused toolkit that helps developers work with YAML — faster and with fewer headaches.

What is DotYAML?

DotYAML is a free, browser-based set of tools for anyone who works with YAML files. Whether you're debugging a Kubernetes manifest, converting a config to JSON, or just trying to remember YAML's multi-line string syntax, DotYAML has you covered.

Every tool on this site runs entirely in your browser. Your YAML is never sent to a server, never logged, never stored. It's as private as your local editor.

Tools available

• ✅ Validator & Formatter Detect syntax errors and reformat with clean, consistent indentation.
• 🔄 YAML ↔ JSON Convert between YAML and JSON instantly, with full structure support.
• ⚙️ YAML → TOML Migrate configs to TOML format used by Rust, Hugo, and more.
• 🔑 YAML → ENV Flatten YAML into .env key=value pairs for CI/CD and Docker.
• 📄 YAML Cheatsheet A complete, printable syntax reference from basics to anchors.

Why we built this

YAML is everywhere — GitHub Actions, Kubernetes, Docker Compose, Ansible, Helm — yet the tooling for working with it is fragmented. Some validators are slow or send your data to a server. Some converters don't handle edge cases like anchors or multi-document files. Many are cluttered with ads or paywalls.

DotYAML was built to be the tool we always wanted: fast, clean, private, and free.
