from spire.doc import *
from spire.doc.common import *

# Initialize an instance of the Document class
document = Document()
# Load a Word document
document.LoadFromFile("Test.docm")

# Detect if the document contains VBA macros
if document.IsContainMacro:
    print("The document contains VBA macros.")
else:
    print("The document does not contain any VBA macros.")
    
document.Close()

Remove VBA Macros from a Word Document in Python

Developers can remove all macros from a Word document at once by using the Document.ClearMacros() method. The detailed steps are as follows.

• Initialize an instance of the Document class.
• Load a Word document using the Document.LoadFromFile() method.

Extract Text from a Textbox in Word

Using Spire.Doc for Python, you can access a specific text box in a document by utilizing the Document.TextBoxes[index] property. After retrieving the text box, you can iterate through its child objects to identify whether each one is a paragraph or a table. If the object is a paragraph, you can retrieve its text using the Paragraph.Text property. In cases where the object is a table, you will need to loop through each cell to extract text from every individual cell within that table.

The steps to extract text from a text box in a Word document are as follows:

• Create a Document object.
• load a Word file by using Document.LoadFromFile() method.
• Access a specific text box using Document.TextBoxes[index] property.
• Iterate through the child objects within the text box.
• Determine if a child object is a paragraph. If it is, retrieve the text from the paragraph using Paragraph.Text property.
• Check if a child object is a table. If so, iterate through the cells in the table to extract text from each cell.

from spire.doc import *
from spire.doc.common import *

# Create a Document object
document = Document()

# Load a Word file
document.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx")

# Get a specific textbox
textBox = document.TextBoxes.get_Item(0)

with open('ExtractedText.txt','w') as sw:

    # Iterate through the child objects in the textbox
    for i in range(textBox.ChildObjects.Count):

        # Get a specific child object    
        object = textBox.ChildObjects.get_Item(i)

        # Determine if the child object is paragraph
        if object.DocumentObjectType == DocumentObjectType.Paragraph:

            # Write paragraph text to txt file
            sw.write((object if isinstance(object, Paragraph) else None).Text + "\n")

        # Determine if the child object is table
        if object.DocumentObjectType == DocumentObjectType.Table:
            table = object if isinstance(object, Table) else None
            for i in range(table.Rows.Count):
                row = table.Rows[i]
                for j in range(row.Cells.Count):
                    cell = row.Cells[j]
                    for k in range(cell.Paragraphs.Count):
                        paragraph = cell.Paragraphs.get_Item(k)

                        # Write paragrah text of a specific cell to txt file
                        sw.write(paragraph.Text + "\n")

# Dispose resources
document.Dispose()

Update Text in a Textbox in Word

To update a textbox in a Word document, start by clearing its existing content with the TextBox.ChildObjects.Clear() method. This action removes all child objects, including any paragraphs or tables currently contained within the textbox. After clearing the content, you can add a new paragraph to the text box. Once the paragraph is created, set its text to the desired value.

The steps to update a textbox in a Word document are as follows:

• Create a Document object.
• Load a Word file using Document.LoadFromFile() method.
• Get a specific textbox using Document.TextBoxes[index] property
• Remove existing content of the textbox using TextBox.ChildObjects.Clear() method.
• Add a paragraph to the textbox using TextBox.Body.AddParagraph() method.
• Add text to the paragraph using Paragraph.AppendText() method.
• Save the document to a different Word file.

from spire.doc import *
from spire.doc.common import *

# Create a Document object
document = Document()

# Load a Word file
document.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx")

# Get a specific textbox
textBox = document.TextBoxes.get_Item(0)

# Remove child objects of the textbox
textBox.ChildObjects.Clear()

# Add a new paragraph to the textbox
paragraph = textBox.Body.AddParagraph()

# Set line spacing
paragraph.Format.LineSpacing = 15.0

# Add text to the paragraph
textRange = paragraph.AppendText("The text in this textbox has been updated.")

# Set font size
textRange.CharacterFormat.FontSize = 15.0

# Save the document to a different Word file
document.SaveToFile("UpdateTextbox.docx", FileFormat.Docx2019);

# Dispose resources
document.Dispose()
