frequently asked questions
how are types inferred?
types come from the sample values. arrays of objects are merged, and keys missing from some items become optional.
interface or type alias?
pick either. nested objects become separate named declarations based on their key names.
is my json uploaded?
no. generation runs entirely in your browser.
