Open .XLT files
It seems that Excel 97-2003 templates (.XLT) are not supported, or at least they are not listed in the Open dialog on Windows

You can open .XLT files from context menu (right-click on the file) > Open in...
Alternatively, you can open such file from Desktop Editors main screen > Open local file > Browse > select "All files" in Open Document dialog and find your .XLT file.I have to mention that ONLYOFFICE editors natively work with OOXML formats, .XLT is a legacy format. Upon saving, you cannot save it back in this format, insead you can save it as .XLSX or .XLTX.
Let me know if it works for you.
