What is an OTS file?

An OTS file is a spreadsheet template created by the Calc program included in Apache OpenOffice (formerly OpenOffice.org) or another spreadsheet application that supports the OpenDocument standard. It contains a spreadsheet saved in OASIS' OpenDocument XML-based formatting. OTS files allow users to create multiple .ODS spreadsheet files using the same styles and formatting.
