How do I copy the contents of a word document?


I want to write a program that copies text from a Word document and pastes it to another. I'm trying to do that using the python-docx library. I was able to do that with the following code, but it does not copy the bold, italic, underlined nor colored parts as they are and only their text:

from docx import Document


input = Document('SomeDoc.docx')

paragraphs = []
for para in input.paragraphs:
    p = para.text
    paragraphs.append(p)

output = Document()
for item in paragraphs:
    output.add_paragraph(item)
output.save('OutputDoc.docx')

I've also tried copying the paragraph object directly into the output document, but it doesn't work either:

from docx import Document


input = Document('SomeDoc.docx')
output = Document()

for para in input.paragraphs:
    output.add_paragraph(para)
output.save('OutputDoc.docx')

Solution

  • In order to copy the text with its styles, you will need to write your own function, as there is no python-docx function that does such a thing. This is the function I wrote:

    def get_para_data(output_doc_name, paragraph):
        """
        Write the run to the new file and then set its font, bold, alignment, color etc. data.
        """
    
        output_para = output_doc_name.add_paragraph()
        for run in paragraph.runs:
            output_run = output_para.add_run(run.text)
            # Run's bold data
            output_run.bold = run.bold
            # Run's italic data
            output_run.italic = run.italic
            # Run's underline data
            output_run.underline = run.underline
            # Run's color data
            output_run.font.color.rgb = run.font.color.rgb
            # Run's font data
            output_run.style.name = run.style.name
        # Paragraph's alignment data
        output_para.paragraph_format.alignment = paragraph.paragraph_format.alignment
    

    How The Function Works

    1. Adds a new paragraph object to the file.
    2. Adds a new run to that paragraph.
    3. Checks whether each of the styles bold, italic and underline is True, False, None. If it's True, the run will be in that style, if it's False, it won't be in that style, and if it's None, it will be inherited by the default style of the paragraph it's in. Then it applies the styles to the run.
    4. Checks what's the color of the run in RGB and applies the found color to the run.
    5. Checks what's the font of the run and applies the found font to the run.
    6. Checks what's the alignment of the run and applies the found alignment setting to the run.

    How to Use the Function:

    You need to give it the name you gave your output document and the paragraphs you want to copy. For Example:

    # Imports
    
    input_doc = Document('InputDoc.docx')
    output_doc = Document()
    
    # Call the function
    get_para_data(output_doc, input_doc.paragraphs[3])
    
    # Save the new file
    output_doc.save('OutputDoc.docx')
    

    If you'd like to copy the entire document I suggest you do this:

    for para in input_doc.paragraphs:
        get_para_data(output_doc, para)
    
    output_doc.save('OutputDoc.docx')
