Simple tutorial: Go language to convert PDF to word document

A concise tutorial on converting PDF to Word document using Go language

Overview

PDF to Word document is to convert PDF format files into Word format files, which are often encountered in actual work. The Go language provides a wealth of libraries and tools that can help us easily convert PDF to Word documents. This article will introduce how to use Go language to convert PDF to Word document, and provide specific code examples.

Required libraries and tools

• Go language development environment
• PDF conversion library, such as pdfcpu, pdftohtml, ghostscript, etc.
• Word document editing Libraries, such as docx, docx-gen, etc.
• Text processing libraries, such as regexp, strings, etc.

Code examples

package main

import (
    "fmt"
    "io"
    "os"

    "github.com/unidoc/unipdf/v3/extractor"
)

func main() {
    // PDF文件路径
    pdfFile := "path/to/pdf_file.pdf"

    // Word文档路径
    wordFile := "path/to/word_file.docx"

    // 读取PDF文件
    f, err := os.Open(pdfFile)
    if err != nil {
        fmt.Println("Error opening PDF file:", err)
        return
    }
    defer f.Close()

    // 创建PDF解析器
    r, err := extractor.New(f)
    if err != nil {
        fmt.Println("Error creating PDF parser:", err)
        return
    }

    // 解析PDF文件
    text, err := r.Text()
    if err != nil {
        fmt.Println("Error parsing PDF file:", err)
        return
    }

    // 创建Word文档
    w, err := os.Create(wordFile)
    if err != nil {
        fmt.Println("Error creating Word file:", err)
        return
    }
    defer w.Close()

    // 写入Word文档
    w.Write([]byte(text))

    fmt.Println("PDF file converted to Word file successfully.")
}

Running examples

1. Ensure that the Go language development environment and required libraries and tools have been installed.
2. Place the PDF files and code sample files in the same directory.
3. Switch to the directory in the terminal and run the following command:

go run main.go

4. After successful operation, you will find the converted Word document in the current directory.

Summary

This article introduces how to use Go language to realize the function of converting PDF to Word document, and provides specific code examples. By using the PDF conversion library and Word document editing library, we can easily realize the function of converting PDF to Word documents to meet the needs of actual work.
