How do you extract data from a PDF file in Python?

Python has an amazingly long list of language processing libraries (SpaCy, Regex, Transformers) and APIs which can be used along with PDF reading libraries to create your own datasets and pre-process that data.

- Simplicity: Python's clean syntax ensures readability, making it accessible for both beginners and seasoned developers. - Rich Libraries: Leveraging PyPDF2 and pdfminer, Python offers versatile tools for reading, merging, and extracting text from PDFs. - Community Support: Python's active community on forums like Stack Overflow provides abundant knowledge and assistance. - Cross-Platform Compatibility: Python maintains consistent behavior across Windows, macOS, and Linux, ensuring universal functionality. - Data Science Integration: Seamless incorporation with data science tools like pandas facilitates in-depth analysis of extracted PDF data.

Python's combination of readability, extensive libraries, community support, and versatility makes it a preferred choice for extracting data from PDF files. Depending on the complexity and structure of the PDF data, developers can choose the most suitable library for their specific requirements. Here are some reasons why Python. - Python has a simple and readable syntax so East To Learn - Easy Integration with Other Tools - Python is open-source - Cross-Platform Compatibility. - Suitable library for their specific requirements. - Python is one of the most secure programming languages.

I chose Google Docs to solve this problem by 1. Convert PDF to JPG 2. Access Google Docs then import a JPG image. 3. Export file by downloading it. 4. You will get an extract data from PDF that is nearly 100% correct, accurate, and structure unchanged. 5. Python may useful after this when you want an analytics.

Extracting data from PDF files in Python can be done using various libraries, and the choice depends on the complexity and structure of the PDF. Two popular libraries for working with PDFs in Python are PyPDF2 and PyMuPDF Here's a basic example using PyPDF2 to extract text from a PDF file import PyPDF2 def extract_text_from_pdf(pdf_path): with open(pdf_path, 'rb') as file: pdf_reader = PyPDF2.PdfFileReader(file) num_pages = pdf_reader.numPages text = '' for page_num in range(num_pages): page = pdf_reader.getPage(page_num) text += page.extractText() return text pdf_path = 'path/to/your/file.pdf' extracted_text = extract_text_from_pdf(pdf_path) print(extracted_text)

You can use PyPDF2. Here's a basic example of extracting text: import PyPDF2 with open('your_pdf_file.pdf', 'rb') as file: pdf_reader = PyPDF2.PdfFileReader(file) # Extract text from each page for page_num in range(pdf_reader.numPages): page = pdf_reader.getPage(page_num) text = page.extractText() print(text)

So you need to install the PyPDF2 library First. -pip install PyPDF2 Once you have it installed # creating a pdf reader object reader = PyPDF2.PdfReader('example.pdf') # print the number of pages in pdf file print(len(reader.pages)) # print the text of the first page print(reader.pages[0].extract_text())

1. Choose Your Library: Opt for PyPDF2, a versatile and user-friendly library for basic PDF operations. 2. Installation: Install PyPDF2 using pip: `pip install PyPDF2`. 3. Import the Library: Import PyPDF2: `import PyPDF2`. 4. Open PDF File: Use the `open()` function to access the PDF file: pdf_file = open('your_file.pdf', 'rb') 5. Create PDF Reader Object: pdf_reader = PyPDF2.PdfReader(pdf_file) 6. Extract Text: text = pdf_reader.getPage(page_number).extract_text() 7. Iterate Through Pages: for page_num in range(pdf_reader.numPages): page_text = pdf_reader.getPage(page_num).extract_text() print(f"Page {page_num + 1}:\n{page_text}\n") 8. Close the PDF File: After extraction, close the PDF file: `pdf_file.close()`.

I use Pdfplumber package in python to extract text from PDF. Further, I combine my work with Regx package (Regular expression) to extract data I want it. Next, I store the data in dictionary format {key: value} pair for further use.

Python’s vast number of libraries allow you to have several options to parse your PDFs. For simple PDFs with only text, I use PyPDF2 as it lets me get digital text off my PDFs to be able to process it further using Pandas or several NLP libraries and APIs

I use PyMuPDF which is also known as Fitz involves open a pdf file, accessing its pages and extract text/images. Once it is extracted the data from each page, I can store it in a list initially, then convert the list into a dataframe using Pandas. For the dataframe I will provide the required page number or range and list to extract content, And Further this dataframe can be exported for analysis and manipulations.

1. Install PyPDF2: Begin by installing the PyPDF2 library using the command `pip install PyPDF2`. 2. Import PyPDF2: `import PyPDF2`. 3. Open PDF File: `pdf_file = open('your_file.pdf', 'rb')`. 4. Create PDF Reader Object: Initialize a PDF reader object: `pdf_reader = PyPDF2.PdfReader(pdf_file)`. 5. Access Metadata: author = pdf_reader.getDocumentInfo().author title = pdf_reader.getDocumentInfo().title subject = pdf_reader.getDocumentInfo().subject 6. Get Number of Pages: `num_pages = pdf_reader.numPages` 7. Parse Text from a Page: page_number = 1 # Replace with desired page number page_text = pdf_reader.getPage(page_number - 1).extract_text() 8. Close the PDF File: pdf_file.close()

1. Page Count: Assess the total pages with `pdf_reader.numPages`. 2. Iterate Pages: Use a loop to traverse pages: for page_num in range(pdf_reader.numPages): page = pdf_reader.getPage(page_num) # Your operations on each page 3. Text Extraction: Extract text from a specific page: page_number = 1 # Replace with desired page number page_text = pdf_reader.getPage(page_number - 1).extract_text()

The easier way to get this done using Python open source packages, and parsing the information in the form of key value pairs. The reason for saying KV pairs here would be very useful if you may have to match/map the values with the keys in some other format or something.

Tabula-py can be used, but that may not be suitable for all use cases. Camelot can be good too. I have tried to combine some OpenCV models to change the files to image and read the image thru to identify the tables in it and put it in a proper format. Again, this is just an experimentation taken place.

I've encountered similar challenges extracting tables from PDFs using pdfplumber and Pytesseract (with OCR), especially with lineless and variable row heights. Post-extraction, pandas is the way to go.

I highly recommend everyone to build a resume PDF parser. came across the problem of parsing PDFs with Python to build a resume parser myself to see how job ATS systems read and view resume. Seeing a resume with your eyes is very different from how computers read it. I hacked together a simple PyPDF2 parser to see how my PDF converted to text and the impact font, font size, spacing, etc had on the end result and it was mind blowing.
