strange message about file format

[AliveDD]

im install plugin into my app with options:

    $("#restaurant_stat").table2excel({
        exclude: ".noExl",
        name: "SmartReserve",
        filename: xlsFilename,
        fileext: ".xls",
        exclude_img: false,
        exclude_links: false,
        exclude_inputs: false
    });

my table are converted, but on the run i have Strange message:

help e please

Correct, because the files is an xlsx, but others have opted to change the extension provided by default in the code. Excel doesn't handle the file properly then either though (it's buggy) so really that message is "normal" given then approach.

Also, please understand that this isn't support. If you're going to post an issue, please first read the README at least. In this case I'd hope that you would take away that this is a hack and there are numerous issues inherent to it.
