Use $type to report the JSON type at several useful paths.

  • Real JSONata 2.2 query
  • Private in your browser
  • Time and result safety caps

Inspect JSON value types

Paste JSON, edit the JSONata expression, and run it locally with time, depth, and result limits.

JSONata can filter, sort, group, calculate, and reshape the sample without an upload.

Three simple steps

How to use it

Your JSON stays on this device

JSONata reads and transforms the JSON inside this browser tab. Bookify does not upload or save the data or expression. Every run has time, sequence, stack, input, and output limits, and $eval stays disabled.
