YAMLine

About YAMLine

YAMLine is a browser-based tool that converts YAML to JSON and JSON to YAML. Users input content by pasting text or uploading a file into an editor, and the converted result appears in a second editor, which can then be copied to the clipboard or downloaded as a file.

The tool also provides an API for programmatic YAML-to-JSON conversion via a POST request to api.yamline.com/convert/yaml/json, which accepts YAML data as payload and returns the corresponding JSON, or a 400 error if the input is invalid.

It is intended for developers who need to convert between YAML, commonly used for configuration files, and JSON, commonly used for data exchange in web applications and APIs.
