YAML configs are easy to read, but your code usually needs JSON. This page bridges them: paste YAML and run yaml to json in your browser, free, with strict parsing that catches errors. It is a yaml to json converter that keeps your data on your device.
Config format in, data format out.
Paste a YAML document and the parser reads its indentation and structure, then writes the JSON equivalent with proper nesting and types. The parsing is strict, so a misplaced indent or a stray character is flagged rather than guessed, which doubles as a yaml format online sanity check.
People reach it as yaml to json or a yaml to json converter, usually when a config needs to become data their code can read. The whole job runs in your browser, so even a private config stays on your machine.
The reverse direction.
The trip runs both ways. When you have JSON and want a readable config, the JSON to YAML tool handles json to yaml. Keep both pages handy and you can switch between a human-friendly YAML config and machine-friendly JSON whenever a tool on either side expects the other format.
What this page does not do.
This converts YAML rather than edits it, and there is no separate yaml editor online on the site yet, so heavy editing belongs in your code editor. If your input is not YAML at all, a broader json file converter or a string to json converter online is a better fit, and the JSON Formatter cleans loose objects or raw text into valid JSON.
Stop reading. Start using.
That is everything worth saying. Open the tool and try it on something real. You will know within a minute whether it belongs in your kit.
