OpenDocument Spreadsheet Template (OTS) files are template files used for creating spreadsheet documents using the OpenDocument format. OTS files contain a pre-defined set of data and styles that can be used to quickly create a spreadsheet, such as a price list or accounting ledger. The OTS format is supported by many spreadsheet programs, including OpenOffice, LibreOffice, and Microsoft Office.
XLK files are Microsoft Excel Backup Files, which are created as backup copies of Excel files (.XLS or .XLSX). They contain a copy of the excel file in its original state, and can help to restore a file if the original is lost, damaged or corrupted.
