NodeJS Excel文件 xls格式转xlsx文件格式

思路：读取xls文件--》生成xlsx文件

import xlsx from 'xlsx';/*** xls文件转化为xlsx* @param filepath*/export function transXlsForXLSX(filepath: string){const workBook = xlsx.readFile(filepath);// console.log(workBook.SheetNames);const workbook_save = {SheetNames: [],Sheets: {},};for (const sheet of workBook.SheetNames) {const objs = xlsx.utils.sheet_to_json(workBook.Sheets[sheet]);// console.log(objs);workbook_save.SheetNames.push(sheet);workbook_save.Sheets[sheet] = xlsx.utils.json_to_sheet(objs);}const filename = filepath.substring(0, filepath.lastIndexOf('.')) + '.xlsx';xlsx.writeFile(workbook_save, filename);return filename;}
