Create or Open Document

The godocx library allows you to create new DOCX documents as well as make modifications to existing ones.

Opening a Document

To get started, you can either create a new document or open an existing one. Here’s a brief overview of how you can do both:

Creating a New Document

To create a new DOCX document from scratch, you can use the NewDocument function. This initializes a new document with the default template and allows you to begin adding content to it.

package main

import (
    "log"
    "github.com/gomutex/godocx"
)

func main() {
    // Create a new document
    document, err := godocx.NewDocument()
    if err != nil {
        log.Fatal(err)
    }
    
    // Add a heading
    document.AddHeading("Document Title", 0)
    
    // Save the document to a file
    err = document.SaveTo("demo.docx")
    if err != nil {
        log.Fatal(err)
    }
}

Opening an Existing Document

If you have an existing DOCX file and want to modify it, you can open it using the godocx.OpenDocument function. This allows you to load the contents of the file into a godocx.Document object and make changes as needed.

package main

import (
    "log"
    "github.com/gomutex/godocx"
)

func main() {
    // Open an existing document
    document, err := godocx.OpenDocument("existing-document.docx")
    if err != nil {
        log.Fatal(err)
    }
    
    // Modify the document content as needed
    
    // Save the modified document to a new file
    err = document.SaveTo("modified-document.docx")
    if err != nil {
        log.Fatal(err)
    }
}
