.ODS File Extension

Calc is one of several programs available in the OpenOffice suite and is similar to the Excel program available in the Microsoft Office suite. The ODS file is the main file used by Calc to save spreadsheets the same way that Excel saves spreadsheets in the .XLSX file. Although Microsoft Office is the most popular productivity suite many users download the OpenOffice suite as a free alternative. You may see the ODS file in the workplace, school, or home environments.

OpenDocument spreadsheet files can be opened and edited with any OpenOffice-compatible program, including: NeoOffice (Mac) and LibreOffice (Mac & Windows). ODS files can also be opened in Microsoft Excel and saved as .XLS or XLSX files.

NOTE: Apache OpenOffice was previously known as OpenOffice.org.
