Excel列信息

js代码如下：

var X = XLS;
function to_json(workbook) {
    var result = {};
    workbook.SheetNames.forEach(function (sheetName) {
        var roa = XLS.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);
        if (roa.length > 0) {
            result[sheetName] = roa;
        }
    });
    return result;
}

function fixdata(data) {
    var o = "", l = 0, w = 10240;
    for (; l < data.byteLength / w; ++l) o += String.fromCharCode.apply(null, new Uint8Array(data.slice(l * w, l * w + w)));
    o += String.fromCharCode.apply(null, new Uint8Array(data.slice(l * w)));
    return o;
}

function process_wb(wb,type) {
    var output = "";
    switch (type) {
        case "json":
            output = JSON.stringify(to_json(wb), 2, 2);
            break;
        case "form":
            output = to_formulae(wb);
            break;
        default:
            output = to_csv(wb);
    }
    //if (out.innerText === undefined) out.textContent = output;
    //else out.innerText = output;
    return output;
}
