About YAML Converter

YAML Converter is an independent, ad-supported developer utility for converting between YAML, JSON, and TOML. It is built around one observation: most converters online either do too little (one direction only) or too much (15 formats, three nested editors, a paywall) — and almost all of them make you scroll past five banners before you can paste anything.

What makes this different

Three formats, six directions. YAML ⇄ JSON ⇄ TOML. That's the working set most developers actually need.
No ads inside the editor. The converter's first fold is the editor. Ads, if any, sit below the fold or on guides.
Parsing happens on your device. js-yaml, smol-toml, and the browser's JSON parser run in your tab — there is no server in the loop.
Each format gets a primer. Anchors and aliases in YAML, the JSON5 question, why TOML's date type is its own thing. We'd rather give you a five-minute read than send you to spec PDFs.

Who runs this

YAML Converter is a one-person project operated from South Korea as part of a small portfolio of focused web utilities. To get in touch, use the contact page or email facered79@gmail.com.

How it's built

The site is a static Astro build served by Nginx on an Oracle Cloud Always Free instance. The conversion libraries are bundled at build time and loaded only on converter pages, so the rest of the site stays light. There is no user account, no tracking pixel for your config, and no server-side analytics of your input. See the Privacy Policy for the full picture.

Roadmap in brief

YAML ⇄ JSON ⇄ TOML converter with bidirectional editor — in progress
Per-pair landing pages (/yaml-to-json/, etc.) — in progress
Format primers (anchors, JSON5, TOML dates) — in progress
Schema-aware validation hints (e.g. for Kubernetes manifests) — later
Optional server-side conversion API for very large files — later

Support the project

If this tool saves you time, the best thing you can do is link to it from a teammate's PR. Ad revenue funds the server bill; word of mouth funds the motivation.
