CSV

A CSV (Comma-Separated Values) file is a simple text file used to store tabular data, such as a spreadsheet or database. Each line in the file corresponds to a row in the table, and within each line, columns are separated by commas.

JSON Lines / NDJSON

JSON Lines (also known as NDJSON — Newline Delimited JSON) is a text format where each line is a self-contained, valid JSON value, typically a JSON object. It is widely used for streaming data, log files, and large data exports because files can be read and written one record at a time without loading the entire document into memory. Common file extensions are .jsonl and .ndjson.
