.ODS File Extension

Mailbox or "message store" for e-mail messages created or saved in Outlook Express 5; similar to a .DBX file used by other versions of Outlook Express.

An ODS file is a spreadsheet created by Calc, a spreadsheet program included in the Apache OpenOffice suite. It stores data in cells that are organized into rows and columns, and it may also contain charts, mathematical functions, and formatting. ODS files are similar to .XLSX files.

You can open an ODS file in a variety of spreadsheet programs, including:

• OpenOffice Calc (cross-platform)
• Microsoft Excel (cross-platform)
• LibreOffice (cross-platform)
• Google Sheets (Web, iOS, Android, Chrome OS)

In all of those programs, you can also convert your ODS file to an XLSX file. Note that you may lose some formatting when you open an ODS file in a program other than OpenOffice or LibreOffice or convert an ODS file to another spreadsheet format.
