What are Spreadsheet Files? Definition and list of extensions

Spreadsheet files store data in cells, which are arranged in rows and columns. Each cell can contain a certain type of data such as text, number or date. Cells can also contain formulas, which refer to other cells. A formula defines how the contents of that cell are calculated from the contents of one or more cells.
A spreadsheet is a computer application or program that simulates a document, spreadsheet or accounting. Spreadsheets are frequently used for statistical or financial information due to their ability to automatically calculate the entire sheet after a change is made to a single cell.
Examples of spreadsheet programs include Microsoft Excel, Lotus 1-2-3, Apple Numbers, OpenOffice Calc, Gnumeric, Quatro Pro, and others.
Common spreadsheet file extensions include .XLSX, ODS, and .NUMBERS.
