Since it's a ClarisWorks/AppleWorks file, add the .cwk file extension. Newer versions of Numbers (since October, 2013) can't open these files but LibreOffice can. You can download it at https://www.libreoffice.org. I was able to open an AppleWorks 6 spreadsheet just now in LibreOffice.

I find that happens with very old files I've copied over from a much older Mac, usually on with image files. First, try adding the .numbers extension to the file name in Finder.

Thank you, Peggy. (Got email telling me to reply to Peggy's response. This was puzzling. My name is Peggy, too.)

I tried adding .numbers and got a "The file format is invalid" window. Realized I had created it in ClarisWorks, and had tried (in 2002 or so) to make numbers the default for all those spreadsheets. Some converted but not all. A lost cause?
