How do I check if an Excel file (.xlsx) exists on the SD card on Android using PhoneGap? If the file exits, how do I then import and export the file contents through javascript?

First add the cordova File Plugin into your project.Then use the following code :

    var reader = new FileReader();
    var fileSource = <file path>;

    reader.onloadend = function(evt) {

        if(evt.target.result != null) {
            // If you receive not null value the file exists
        } else {
            // Otherwise the file doesn't exists
        }         
    };

    // We are going to check if the file exists
    reader.readAsDataURL(fileSource);
