Wrong xls filetype

I’ve been converting .ods files to .xls binary format in headless mode using the convert-to option. Every time I use the command, it converts the file to the 95/5.0 version of xls, not the 97-2003 version. Is there any way to specify which type of .xls to convert to using the convert-to option?

It looks like you’ll want to do something like

soffice --headless --convert-to xls:"MS Excel 97" your-spreadsheet.ods
