How to use the xlsx.utils.sheet_to_json function in xlsx

async importExcel(fileBuffer: any, modelName: string) {
    const workbook = read(fileBuffer, {});
    const worksheet = workbook.Sheets[workbook.SheetNames[0]];
    const jsonArray = utils.sheet_to_json(worksheet, { header: 1 });
    const repository = await this.getRepository(modelName);
    const schemas = await this.getSchemas(repository);
    const status = [];
    for (let row = 1; row < jsonArray.length; row += 1) {
      const entity = repository.create();
      for (const [column, element] of schemas.entries()) {
        if (jsonArray[0][column] === element.config.info.name) {
          const keyName = element.name;
          let value = jsonArray[row][column];
          // 如果是外键关系表，则需要处理外键表数据
          if (element.config.selectable !== undefined) {
            const tempRepo = await this.getRepository(element.config.selectable);
            if (!element.config.many) {
              const res = await tempRepo.findOne({ name: jsonArray[row][column] } as any);
              value = res;
            } else {

const workbook = xlsxRead(binaryData, { raw: options.rawData as boolean });

				if (workbook.SheetNames.length === 0) {
