Excel Binary Workbook

Excel Binary Workbook (.xlsb) is a Microsoft Excel file format that stores spreadsheet data in a binary format that makes it faster and more efficient for handling large datasets. It supports all Excel features.

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.
