Frequently Asked Questions
Does this preserve YAML types?
Numbers, booleans, strings, nested maps, and lists are emitted as JavaScript literals. Dates and custom tags follow js-yaml parsing rules.
Can I omit the const wrapper?
Yes. Turn off the wrap option to copy only the object literal, useful inside existing assignments or function arguments.
Is my data sent to a server?
No. Parsing and formatting run entirely in your browser.
