Material preparation: computer, network.

Operating steps:

1. Search for speedpdf first, and then open this online conversion tool. This is an international English web page, but don't worry about opening it very fast in China. If you are not used to English pages, you can right-click anywhere on the webpage and select "Translate into Chinese (Simplified)" to display commonly used Chinese pages.

2. Then select "CAJ to Word" in the homepage recommendation or find CAJ to Word in the "All Tools" drop-down menu. (If the downloaded paper is PDF, you can also use this tool to convert PDF into Word in the same way).

3. After entering the conversion page, click the upload document page according to the page prompts, and select CAJ document upload, which supports uploading multiple documents in batches at the same time, and then convert. You can select multiple documents at once and drag them to this upload page.

4. After the file is uploaded successfully, all uploaded document records will be displayed synchronously below, and click "Convert" to start. Generally, a document can be successfully converted in a few minutes, and documents can be added at the same time without affecting the current conversion progress. After the conversion is completed, the conversion button will automatically become a download button, which can be downloaded and consulted by clicking it.
