Javascript 读取节点js中的xls文件时出现问题，文件头从第1行开始，因为第0行包含第1列中的值，只有其他列为空

这是我用来读取xls文件的代码，它给出了输出

{
    "ClientAUM": "Product Code",
    "__EMPTY": "Fund",
    "__EMPTY_1": "Number",
    "__EMPTY_2": "Code,
    "__EMPTY_3": "Option",
    "__EMPTY_4": "Description",
    "__EMPTY_5": "Balance",
    "__EMPTY_6": "Pledged",
    "__EMPTY_7": "Date",
    "__EMPTY_8": "Type",
    "__EMPTY_9": "Hold Mode",
    "__EMPTY_10": "Agent Code",
    "__EMPTY_11": "Broker Code",
    "__EMPTY_12": "P-OUT Code",
    "__EMPTY_13": "Investor ID",
    "__EMPTY_14": "Name",
    "__EMPTY_15": "Address #1",
    "__EMPTY_16": "Address #2",
    "__EMPTY_17": "Address #3",
    "__EMPTY_18": "City",
    "__EMPTY_19": "Pincode",
    "__EMPTY_20": "Phone Residence",
    "__EMPTY_21": "Phone Office",
    "__EMPTY_22": "Fax",
    "__EMPTY_23": "Email",
},

为什么在输出的末尾有一个逗号？你从哪里得到的？返回的就这些吗？这是我为ref复制的唯一一个对象，我在输出中得到一个数组

{
    "ClientAUM": "Product Code",
    "__EMPTY": "Fund",
    "__EMPTY_1": "Number",
    "__EMPTY_2": "Code,
    "__EMPTY_3": "Option",
    "__EMPTY_4": "Description",
    "__EMPTY_5": "Balance",
    "__EMPTY_6": "Pledged",
    "__EMPTY_7": "Date",
    "__EMPTY_8": "Type",
    "__EMPTY_9": "Hold Mode",
    "__EMPTY_10": "Agent Code",
    "__EMPTY_11": "Broker Code",
    "__EMPTY_12": "P-OUT Code",
    "__EMPTY_13": "Investor ID",
    "__EMPTY_14": "Name",
    "__EMPTY_15": "Address #1",
    "__EMPTY_16": "Address #2",
    "__EMPTY_17": "Address #3",
    "__EMPTY_18": "City",
    "__EMPTY_19": "Pincode",
    "__EMPTY_20": "Phone Residence",
    "__EMPTY_21": "Phone Office",
    "__EMPTY_22": "Fax",
    "__EMPTY_23": "Email",
},
