In the further part of this page we have added a list of programs that should open your OTS file. It is enough you choose a proper application for your operating system, download and install it.


The file extension OTS identifies template files of the open source spreadsheet Calc.
An OTS file contains formatting, formulas, and data that serve as the basis for creating multiple ods (spreadsheets) tables with the same characteristics. Ots files can also contain macros. These macros may contain malicious code, which is why you should do a virus scan before running it.
The template files can be created by the user or come from third-party providers.
The OTS format is part of the Open Document for Office Application Standard, also known as OpenDocument. Originally developed by Sun Microsystems and based on XML, the standard has been defined and developed by the Organization for the Advancement of Structured Information Standards (OASIS).
OpenDocument is the native format of OpenOffice.Org Suite. Ots is a standard spread of the spreadsheet OpenOffice.Org Calc.

How to open a OTS file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the OTS file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a OTS file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support OTS files. At this point we are looking for disk space where the application was installed in and we can link it with a OTS file. Since then, our operating system will use the selected program to support all OTS files.

Other issues

Despite the described problem with OTS there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the OTS file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the OTS file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
