antd本地上传excel文件并读取文件的数据转为json

1.写一个上传

这里直接用upload组件即可

<Upload {...uploadProps} maxCount={1} accept={".xlsx"}><Button icon={<UploadOutlined />}>{`${formatMessage({id: 'clk_upload'}, {file: formatMessage({id: 'excel_file'})})}`}</Button></Upload>

2.写props

const uploadProps: any = {onRemove: (file: any) => {const index = fileList.indexOf(file);const newFileList = fileList.slice();newFileList.splice(index, 1);setFileList(newFileList);},beforeUpload: (file: any) => {let reader = new FileReader();reader.onload = function(event: any) {let data = new Uint8Array(event.target.result);let workbook = XLSX.read(data, {type: 'array'});let worksheet = workbook.Sheets[workbook.SheetNames[0]];let jsonData = XLSX.utils.sheet_to_json(worksheet, {header: 1});reader.readAsArrayBuffer(file);setFileList(file?.name?.includes('xlsx') ? [file]: []);return false;},fileList};

beforeUpload函数里处理上传的数据转成Uint8Array，读取文件中的第一个表，使用.utils.sheet_to_json方法读出json数据，具体在进行处理即可。
