Is my data safe?
Yes. All conversion happens in your browser using js-yaml. No data is ever sent to a server.
How does the conversion work?
JSON to YAML parses JSON and dumps it as YAML. YAML to JSON parses YAML and stringifies it as JSON with 2-space indentation.
What is the largest input supported?
Conversions run in a Web Worker so the page stays responsive; conversions that take too long show a timeout message.
