How to convert docx to doc in nodejs

With the continuous development of technology, we can no longer do without document processing in our work and life. The most common document types in document processing are documents in .doc and .docx formats. Documents in .docx format are often difficult to process due to their complex structure. This article will introduce how to convert .docx documents to .doc documents using Node.js.

1. Understand .docx and .doc formats

.docx and .doc formats are two common document formats in Microsoft. Compared with .doc format, .docx format has many more features and advantages. The document structure in .docx format is relatively complex and contains a lot of XML and ZIP data. Therefore, we need to use appropriate tools to handle this type of document.

2. Use Node.js to convert .docx to .doc format

Node.js is a very popular server-side JavaScript running environment that can automate many tasks, including .docx to .doc format. Below we will introduce how to use Node.js to convert .docx documents to .doc documents:

1. First, we need to install Node.js. It can be downloaded and installed directly from the Node.js official website https://nodejs.org/en/.
2. Then, we need to install the docx-to-doc plug-in, use the following command to install:

npm install docx-to-doc

3. Install After plug-in, we need to write a JavaScript script to convert .docx to .doc format. We can use the following code:

const path = require('path');
const docxToDoc = require('docx-to-doc');

docxToDoc(path.join(__dirname, 'input.docx'))
  .then(data => {
    const outputPath = path.join(__dirname, 'output.doc');
    const writeStream = fs.createWriteStream(outputPath);
    writeStream.write(data);
    writeStream.on('finish', () => {
      console.log('转换完成.');
    });
    writeStream.end();
  })
  .catch(err => {
    console.log('转换失败:', err);
  });

4. Save the above script as a .js file, for example we can name it docxToDoc.js and run the following command to convert:

node docxToDoc.js

5. After the conversion is completed, a .doc file named output.doc will be generated in the same directory, which is the result we need.

3. Summary

Using Node.js to convert .docx documents to .doc format can improve work efficiency and make document processing more convenient. Through the introduction of this article, I believe that everyone has mastered how to use Node.js to implement this operation, and can apply it to actual production work.
