NDJSON

NDJSON (Newline Delimited JSON) is a convenient format for storing or streaming structured data that may be processed one record at a time. Each line in an NDJSON file is a valid JSON object, separated by a newline character.

This format is particularly useful for handling large datasets, as it allows for easy parsing and processing of data line by line without loading the entire file into memory.

Key Features

  • Each line is a self-contained JSON object
  • Simple to read and write sequentially
  • Ideal for streaming and logging applications
  • Supports partial processing of large datasets

NDJSON is commonly used in data pipelines, log processing, and scenarios where you need to append new data to existing files without modifying the entire structure.

JSON

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate.

JSON has become the de facto standard for data exchange on the web, and it is widely used in APIs.

Character encoding

As stated by the RFC 8259, we expect strings in uploaded JSON files to be encoded in UTF-8.

If your file contains non UTF-8 characters, you might get an error when parsing your data.
