How To Convert PDF To Text In Python?
A practical guide to how to convert pdf to text in python, including the key steps and checks for page layout, text, images, tables and editability.
The useful answer to “how to convert pdf to text in python” is not just a sequence of clicks. You also need to know what can change during the operation, which properties the destination validates, and how to catch a bad output before it replaces the source.
With pypdf installed, create a PdfReader for the source and call extract_text() on each page, joining the returned strings in page order.
What this specific task means
Converting PDF and plain text is not always a one-to-one translation.
A reliable workflow for how to convert pdf to text in python
- With pypdf installed, create a PdfReader for the source and call extract_text() on each page, joining the returned strings in page order.
- Write the result as UTF-8 text so accented characters are not lost through the output encoding.
- Handle a missing or empty text result rather than concatenating a null value.
- pypdf extracts existing PDF text; it is not an OCR engine and cannot recognise words in page images.
What changes the quality or accuracy
- The PDF text layer stores positioned text, which need not follow visual paragraph order. Simple XML output can place text into page elements without reconstructing a domain-specific XML schema.
- Check page sequence, paragraph order and special characters. For XML, parse the result and confirm that literal ampersands or angle brackets are escaped correctly.
A minimal Python extraction and its limit
With pypdf installed, create a PdfReader for the source and call extract_text() on each page, joining the returned strings in page order. Write the result as UTF-8 text so accented characters are not lost through the output encoding. Handle a missing or empty text result rather than concatenating a null value. pypdf extracts existing PDF text; it is not an OCR engine and cannot recognise words in page images. Test with a known sentence, a two-column page and a scan to see the distinction.
from pathlib import Path
from pypdf import PdfReader
reader = PdfReader("input.pdf")
text = "\n".join(page.extract_text() or "" for page in reader.pages)
Path("output.txt").write_text(text, encoding="utf-8")Practical test before you process everything
Use a PDF with a two-column paragraph and the phrase A & B on its second page. Compare the extracted text against both columns and inspect the page boundary. If XML is the output, check that the ampersand remains readable after parsing. A valid XML document is not automatically compatible with an invoice or publishing system’s required schema.
Extract useful text without claiming original structure
Use a PDF with a two-column paragraph and the phrase A & B on its second page. Compare the extracted text against both columns and inspect the page boundary. If XML is the output, check that the ampersand remains readable after parsing. A valid XML document is not automatically compatible with an invoice or publishing system’s required schema.
Common problems and fixes
| Problem | Likely cause | What to do |
|---|---|---|
| Output is empty | The source has only page images | Run OCR first |
| Columns interleave | Text positions do not imply reading order | Reorder paragraphs against the source |
| An XML import fails | The receiver expects a different schema | Map the extracted page text to that explicit schema |
Final checklist
- Check page sequence, paragraph order and special characters. For XML, parse the result and confirm that literal ampersands or angle brackets are escaped correctly.
- The saved file opens in the application that will receive it, and the original remains available for correction.
