The implementation principle and steps of Go language PDF to word document

Implementation principle

The implementation principle of PDF to word document is to convert the The content is extracted, then reorganized and typeset according to the format of the word document, and finally a word document is generated.

Implementation steps

1. Extract the content in the PDF document

You can use a third-party library to extract the content in the PDF document. For example pdfminer.six or gopdf. pdfminer.six is ??a pure Python PDF parsing library that can extract text, images, tables and other content in PDF documents. gopdf is a PDF parsing library in Go language, which can also extract text, pictures, tables and other content in PDF documents.

2. Reorganize and format according to the format of the word document

You can use a third-party library, such as docx, to reorganize and format according to the format of the word document . docx is a word document generation library in Go language that can generate word documents.

3. Generate word documents

You can use the docx library to generate word documents. The docx library can reorganize and format the content in the extracted PDF document and generate a word document.

Code example

package main

import (
    "fmt"

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

func main() {
    // Open the PDF file
    pdfFile, err := extractor.Open("input.pdf")
    if err != nil {
        fmt.Println(err)
        return
    }

    // Extract the text from the PDF file
    text, err := pdfFile.GetText()
    if err != nil {
        fmt.Println(err)
        return
    }

    // Create a new word document
    doc := docx.NewDocument()

    // Add a paragraph to the document
    paragraph := doc.AddParagraph()

    // Add the extracted text to the paragraph
    paragraph.AddText(text)

    // Save the word document
    err = doc.SaveToFile("output.docx")
    if err != nil {
        fmt.Println(err)
        return
    }

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

Running results

PDF file converted to word document successfully.
