5 Ways To Extract Text From PDF
Why is Extracting Data from PDF Files Necessary?
The Value of Data Extraction
Portable Document Format, commonly known as PDF files, have been around since Adobe introduced them in 1993. Since their inception by Adobe in 1993, PDFs have become the go-to format for maintaining document integrity across different devices. This format ensures that documents appear the same on any screen, making it perfect for digital sharing and printing. However, this very feature that makes PDFs so reliable also makes them tricky when you need to extract information from them.
But why do we need to extract data from these files today? Well, businesses need to pull out various pieces of information like invoice numbers, dates, opening balances, and bank statement tables. Accurate and efficient PDF data extraction can help businesses save time and money, reduce errors, and make better decisions based on the extracted data.

Real-World Applications of PDF Data Extraction
Businesses deal with a wide array of documents in PDF format daily, including:
- Sales Receipts: Extracting itemized lists and prices for accounting purposes.
- Shipping Manifests: Pulling delivery addresses and shipment details for logistics tracking.
- Employee Records: Extracting personal information and payroll details for HR management.
- Project Proposals: Analyzing project scopes and cost estimates for business planning.
These documents, often generated digitally and shared via email, require efficient data extraction methods. Manually copying text from PDF files and pasting it into tools like Excel or Word can be incredibly tedious and error-prone, especially with scanned documents. This method also doesn’t scale well with larger volumes of data.

Why Is Extracting Data From Pdf Files So Tricky?
Ever tried to pull information out of a PDF file and found it’s not as easy as it looks? Here’s why:
No Hierarchy, No Markup
One big headache with PDF files is that they don’t have any built-in structure. They store characters without context. For instance, “Invoice No: 33455” doesn’t clarify that “Invoice No” is the key and “33455” is the value. This lack of clarity makes data extraction a real puzzle.
Scanned Docs and Images: The OCR Challenge
Dealing with images or scanned PDFs? Good luck! These files lose their character-level data, making it necessary to use Optical Character Recognition (OCR) to pull the text out. But OCR is never 100% accurate, especially if the scan quality is poor.
Unstructured Data and Messy Formats
PDF documents often come with unstructured data and inconsistent formatting—different fonts, styles, colors, tables, images, charts, you name it. This messiness makes it hard to extract data consistently and accurately.
Complex Layouts: Tables and Beyond
PDFs can have really complex layouts. Think tables that go across multiple pages or information scattered all over. These layouts make it tough to get the data into a structured format.
Handling Big Data Volumes
Got a PDF with tons of data? Extracting all that manually is a nightmare. It’s time-consuming and prone to errors. That’s where AI tools for PDF analysis can be a lifesaver, automating the process and ensuring accuracy.

#3 PDF Table Extraction
PDF table extraction tools are specifically designed to pull tables from PDF files and convert them into digital formats like Microsoft Excel or CSV. Odin AI utilizes this technique to validate invoices, leveraging advanced technologies to streamline the invoice verification process. This method ensures high levels of accuracy, efficiency, and compliance by automatically identifying and extracting table data from PDF files, making it easier to handle large volumes of structured data.
#4 Rule-based PDF Data Extraction
Rule-based PDF data extraction with Odin AI involves using Optical Character Recognition (OCR) to read and interpret text from images within PDFs, ensuring that visual data is included in the analysis. This OCR-extracted information is then processed through a pipeline with at least two components: one for key-value extraction (such as Invoice No. and Opening Balance) and another for table extraction (like bank statements). Each component follows hard-coded rules and workflows tailored for different document types. These rules, often written using regular expressions or similar techniques, identify specific patterns within the text.
Odin AI leverages advanced context tracking to maintain a comprehensive understanding of the conversation, utilizing hybrid chunking that directly compares queries to smaller chunks to retrieve larger context chunks for the LLM. Additionally, Odin AI uses advanced vector search technology to enhance its knowledge base capabilities. Vector search involves creating vector representations of data, capturing the meaning and context of unstructured information.
With Odin’s Custom AI Agent builder, you can set up rules to govern how the AI interacts with users, ensuring consistent and relevant responses. This allows for a highly customizable and precise extraction process, adapting to various document types and user needs.
#5 Automate PDF Data Extraction using AI
Automated PDF data extraction solutions come in various forms, from simple OCR tools to enterprise-ready document processing and workflow automation platforms.
Odin AI automates PDF data extraction for invoice validation through it’s Automator feature. It employs OCR to read and interpret text from images within PDFs, ensuring that visual data is included. The system runs unattended automations every 30 minutes, downloading invoice reports from Salesforce, extracting and cross-validating data with order forms and POs, and posting validated invoices.
Odin’s advanced vector search technology enhances data accuracy and retrieval, ensuring efficient and error-free invoice processing. Discrepancies are flagged, and detailed audit reports maintain transparency and compliance.
