Node.js 使用 officecrypto-tool 读取加密的 Excel (xls, xlsx) 和 Word( docx)文档, 还支持 xlsx 和 docx 文件的加密（具体使用看文档）。暂时不支持doc文件的解密
传送门：officecrypto-tool
读取加密的 Excel 示例
一：xlsx-populate // 只支持 xlsx， xlsx-populate 自带了解密功能，// 不过只支持 ecma376 agile 模式，也就是Office 生成的加密的docx，// WPS的就不行， WPS用的是 ecma376 standard 模式const XlsxPopulate = require('xlsx-populate');(async ()=>{ const input = await fs.readFile(`pass_test.xlsx`); const output = await officeCrypto.decrypt(input, {password: '123456'}); const workbook = await XlsxPopulate.fromDataAsync(output); // 或者可先判断文件是否是加密的 const isEncrypted = officeCrypto.isEncrypted(input); let output = input; if (isEncrypted) { output = await officeCrypto.decrypt(input, {password: '123456'}); } const workbook = await XlsxPopulate.fromDataAsync(output); })()二：@zurmokeeper/exceljs https://www.npmjs.com/package/@zurmokeeper/exceljs// 只支持 xlsx @zurmokeeper/exceljs 直接内置了解密功能，完全兼容exceljs v4.3.0const Excel = require('@zurmokeeper/exceljs');(async ()=>{ // 从文件读取, 解密使用密码加密的excel文件 const workbook = new Excel.Workbook(); await workbook.xlsx.readFile(filename, {password:'123456'}); // 从流读取, 解密使用密码加密的excel文件 const workbook = new Excel.Workbook(); await workbook.xlsx.read(stream, {password:'123456'}); // 从 buffer 加载, 解密使用密码加密的excel文件 const workbook = new Excel.Workbook(); await workbook.xlsx.load(data, {password:'123456'});})()三：xlsx// xlsx 支持 xls 和 xlsxconst XLSX = require('xlsx');(async ()=>{ const input = await fs.readFile(`pass_test.xlsx`); // const input = await fs.readFile(`pass_test.xls`); // 或者xls const output = await officeCrypto.decrypt(input, {password: '123456'}); const workbook = XLSX.read(output); // 或者可先判断文件是否是加密的 const isEncrypted = officeCrypto.isEncrypted(input); let output = input; if (isEncrypted) { output = await officeCrypto.decrypt(input, {password: '123456'}); } const workbook = XLSX.read(output);})()四：node-xlsx// 其实 node-xlsx 只是对xlsx 进行了封装，里面还是调用 xlsx 去解析的const nodeXlsx = require('node-xlsx');(async ()=>{ const input = await fs.readFile(`pass_test.xlsx`); // const input = await fs.readFile(`pass_test.xls`); // 或者xls const output = await officeCrypto.decrypt(input, {password: '123456'}); const workbook = nodeXlsx.parse(output); // 或者可先判断文件是否是加密的 const isEncrypted = officeCrypto.isEncrypted(input); let output = input; if (isEncrypted) { output = await officeCrypto.decrypt(input, {password: '123456'}); } const workbook = nodeXlsx.parse(output);})()读取加密的 Word 示例
使用：mammoth officecrypto-tool
const officeCrypto = require('officecrypto-tool');const fs = require('fs').promises;const mammoth = require('mammoth');(async ()=>{ const input = await fs.readFile(`pass_test.xlsx`); const output = await officeCrypto.decrypt(input, {password: '123456'}); await mammoth.convertToHtml({buffer: output}); // 或者可先判断文件是否是加密的 const isEncrypted = officeCrypto.isEncrypted(input); let output = input; if (isEncrypted) { output = await officeCrypto.decrypt(input, {password: '123456'}); } await mammoth.convertToHtml({buffer: output});})()使用其他的word读取库也是一样的道理，先使用 officecrypto-tool 解密以后再用对应的库去处理
