A practical method to convert PDF files to Word documents in Go language

Practical method of converting PDF to Word document in Go language

Preface

PDF and Word are two commonly used document formats, in different scenarios There are different uses below. Documents in PDF format have the advantages of good cross-platform compatibility, high security, and easy storage and transmission, while documents in Word format have the advantages of strong editability, easy modification and formatting, etc. Therefore, in some cases, it is necessary to convert PDF documents to Word documents.

Go language converts PDF to Word document

Go language is an open source, compiled, and general-purpose programming language with simple syntax, excellent performance, and strong cross-platform capabilities. The Go language provides a wealth of libraries and tools that can easily convert PDF to Word documents.

1. Install dependencies

First, we need to install dependent libraries. You can use the following command to install:

go get github.com/unidoc/unipdf/v2
go get github.com/unidoc/unioffice/v3

2. Import dependencies

In the Go file that needs to use the PDF to Word document function, import the dependent library:

import (
    "github.com/unidoc/unipdf/v2/extractor"
    "github.com/unidoc/unioffice/v3"
    "github.com/unidoc/unioffice/v3/common"
    "github.com/unidoc/unioffice/v3/document"
)

3. Read Get PDF document

Use unipdf library to read PDF document:

pdfReader, err := extractor.NewPdfReader(pdfFile)
if err != nil {
    // Handle error
}
defer pdfReader.Close()

4. Create Word document

Use unioffice library Create Word document:

wordDoc := unioffice.NewDocument()

5. Convert PDF document content to Word document content

Use unipdf and unioffice libraries to convert PDF document content For the Word document content:

pages, err := pdfReader.GetPages()
if err != nil {
    // Handle error
}

for _, page := range pages {
    text, err := page.GetText()
    if err != nil {
        // Handle error
    }

    paragraph := wordDoc.AddParagraph()
    paragraph.AddRun().AddText(text)
}

6. Save the Word document

Save the Word document locally:

err = wordDoc.SaveToFile(wordFile)
if err != nil {
    // Handle error
}

Full code example

package main

import (
    "github.com/unidoc/unipdf/v2/extractor"
    "github.com/unidoc/unioffice/v3"
    "github.com/unidoc/unioffice/v3/common"
    "github.com/unidoc/unioffice/v3/document"
)

func main() {
    // Read PDF document
    pdfFile := "path/to/input.pdf"
    pdfReader, err := extractor.NewPdfReader(pdfFile)
    if err != nil {
        // Handle error
    }
    defer pdfReader.Close()

    // Create Word document
    wordDoc := unioffice.NewDocument()

    // Convert PDF document content to Word document content
    pages, err := pdfReader.GetPages()
    if err != nil {
        // Handle error
    }

    for _, page := range pages {
        text, err := page.GetText()
        if err != nil {
            // Handle error
        }

        paragraph := wordDoc.AddParagraph()
        paragraph.AddRun().AddText(text)
    }

    // Save Word document
    wordFile := "path/to/output.docx"
    err = wordDoc.SaveToFile(wordFile)
    if err != nil {
        // Handle error
    }
}
