textract

Warnings

• breaking textract relies heavily on external system-level libraries and executables (e.g., `pdftotext` for PDFs, `antiword` for .doc, `tesseract-ocr` for images, `sox` for audio). Without these, extraction for certain file types will fail with a `ShellError` or `FileNotFoundError`.
  Fix: Install the necessary system dependencies for the file types you intend to process. Refer to the official textract documentation for a comprehensive list based on your operating system (e.g., `apt-get` for Debian/Ubuntu, `brew` for macOS). For instance, for PDF files, ensure `poppler-utils` (which provides `pdftotext`) is installed.
• deprecated As of pip 24.1, `textract 1.6.5` has a non-standard dependency specifier (`extract-msg<=0.29.*`). This will result in a `DEPRECATION` warning during installation and may cause issues with future pip versions.
  Fix: While textract itself needs an update to fix this, users can often mitigate by pinning `pip` to an older version or, if possible, by manually installing `extract-msg` at the specified version before installing `textract`. Consider monitoring the project for an update addressing this, or using a fork like `textract-py3` if it resolves this issue.
• gotcha Handling special characters in filenames (e.g., spaces, non-ASCII characters) can sometimes lead to `FileNotFoundError` or `ShellError` when `textract` passes the filename to underlying command-line utilities.
  Fix: Ensure filenames are URL-encoded if being passed via web contexts, or consider sanitizing/simplifying filenames to alphanumeric characters and underscores before processing, especially on certain operating systems or with specific parsers.
• gotcha While textract 1.5.0 and newer officially support Python 3, older versions were primarily Python 2 compatible. Direct migration from very old codebases might expose subtle compatibility issues if not upgraded properly.
  Fix: Always use textract version 1.5.0 or higher for Python 3 projects. Ensure all project dependencies are also Python 3 compatible. Refer to release notes for `1.5.0` for detailed Python 3 migration notes.
• gotcha UnicodeDecodeError can occur, especially in non-standard environments or with files containing unusual encodings, as `textract` relies on `chardet` for input encoding inference and outputs byte strings that need proper decoding.
  Fix: Explicitly specify the desired output encoding in `textract.process(..., encoding='utf-8')`. If `chardet` struggles, pre-process the file to a known encoding or try different decoding strategies in your application.

Install

• pip install textract Install latest version

Imports

• process

  import textract
  text = textract.process('path/to/file.extension')

Quickstart

Demonstrates how to extract text from a file using `textract.process()`. Note that for many file types (like PDF, DOCX, images), corresponding system-level dependencies are required for successful extraction. The output is a byte string, which typically needs to be decoded to UTF-8.

import textract
import os

# For demonstration, create a dummy text file
dummy_file_path = 'example.txt'
with open(dummy_file_path, 'w') as f:
    f.write('This is some sample text in a TXT file.')

try:
    # Extract text from the dummy file
    text_bytes = textract.process(dummy_file_path)
    text_decoded = text_bytes.decode('utf-8')
    print(f"Extracted text: {text_decoded}")
except Exception as e:
    print(f"An error occurred: {e}")
finally:
    # Clean up the dummy file
    if os.path.exists(dummy_file_path):
        os.remove(dummy_file_path)

# Example for a PDF (requires pdftotext system dependency)
# try:
#     pdf_text = textract.process('path/to/document.pdf')
#     print(pdf_text.decode('utf-8'))
# except Exception as e:
#     print(f"Could not process PDF: {e}. Is pdftotext installed and in PATH?")
