An Object data type is a method for encoding key-value pairs. A single field value may contain one or more sets of key-value pairs.

An Object data type is identified as a set of nested objects in the following format:

{"New York":"NY"}


  • Individual values of an Object type must have unique keys. Values, however, may be repeated.
  • The order of key-value pairs is not guaranteed.
  • The \n and \t escaped characters are supported in inputs for this data type.

NOTE: The Dataprep by Trifacta application recognizes up to 250 unique keys in a column of Object data type.
