Handle to XLSX file dragged and dropped about sheetjs

[redchair123]

That uses the html5 FileReader API: http://www.w3.org/TR/FileAPI/#FileReader-interface -- the processing occurs in your browser (the file is not sent anywhere)

The relevant code is located at: https://github.com/Niggler/js-xlsx/blob/gh-pages/index.html#L85-L100

function handleDrop(e) {
    e.stopPropagation();
    e.preventDefault();
    var files = e.dataTransfer.files;
    var i,f;
    for (i = 0, f = files[i]; i != files.length; ++i) {
        var reader = new FileReader();
        var name = f.name;
        reader.onload = function(e) {
            var data = e.target.result; // <-- 'data' contains the sheet data
            var xlsx = XLSX.read(data, {type: 'binary'});  // <--'xlsx' is an object that holds the relevant data
            process_xlsx(xlsx);
        };
        reader.readAsBinaryString(f);
    }
}
drop.addEventListener('drop', handleDrop, false);

To see how to work with those, look at the definitions of process_xlsx and to_csv and to_json

@vinaychada Look at the code sample from my response. The original data is available in the reader.onload callback (this line: var data = e.target.result; // <-- 'data' contains the sheet data) and the parsed sheet data is available from XLSX.readFile (this line: var xlsx = XLSX.read(data, {type: 'binary'}); // <--'xlsx' is an object that holds the relevant data
