- Description
- An XLSX file is an Excel spreadsheet created by Microsoft Excel or another spreadsheet program, such as OpenOffice Calc or Apple Numbers. It stores data in worksheets, which contain cells arranged in a grid of rows and columns, and may also contain charts, mathematical functions, styles, and formatting. XLSX files are commonly used to store financial data and to create simple or complex mathematical models.
- A JSON Lines file holds one JSON value per line, usually one record per line, so it can be written and read as a stream. Logs, data exports and machine learning datasets use it.
