JSON Delimited is a file format that stores several JSON documents in one file. The JSON documents are separated by a new line.

Additional data types are stored as follows:

  • datetime and date are stored as ISO strings;
  • decimal is stored as a text representation of a decimal number;
  • binary is stored as a base64 encoded string;
  • HexBytes is stored as a hex encoded string;
  • complex is serialized as a string.

This file format is compressed by default.
