DOCX and PPTX Text Extraction
Overview
Extract text content from Microsoft Office files (.docx, .pptx) for subject classification.
Installation
pip install python-docx python-pptx
DOCX Extraction
from docx import Document
def extract_docx_text(docx_path, max_chars=5000):
"""Extract text from DOCX files"""
try:
doc = Document(docx_path)
text = ""
for para in doc.paragraphs:
text += para.text + "\n"
if len(text) > max_chars:
break
return text[:max_chars]
except Exception as e:
return f"Error reading DOCX: {str(e)}"
PPTX Extraction
from pptx import Presentation
def extract_pptx_text(pptx_path, max_chars=5000):
"""Extract text from PPTX files"""
try:
prs = Presentation(pptx_path)
text = ""
for slide_num, slide in enumerate(prs.slides):
if slide_num >= 5:
break
for shape in slide.shapes:
if hasattr(shape, "text"):
text += shape.text + "\n"
if len(text) > max_chars:
return text[:max_chars]
return text[:max_chars]
except Exception as e:
return f"Error reading PPTX: {str(e)}"
Combined Handler
def extract_text_by_type(file_path):
"""Route to appropriate extraction method based on file extension"""
ext = file_path.lower().split('.')[-1]
if ext == 'pdf':
return extract_pdf_text(file_path)
elif ext == 'docx':
return extract_docx_text(file_path)
elif ext == 'pptx':
return extract_pptx_text(file_path)
else:
return ""
Best Practices
- Extract from first 3-5 pages/slides only
- Handle missing text shapes gracefully
- Use consistent character limits across all file types
