However, extracting, editing, or parsing data from these files can be a lot of work to do. In today’s data-driven world, efficiently extracting information from PDF documents is essential. This article talks about the problems with getting data from PDFs and shows how to extract data from PDFs to Excel online. Whether you need to get text, and tables, or make PDFs searchable, we’ll cover solutions that are fast, accurate, and easy to use. Challenges in PDF Data Extraction: Let’s explore some of the key challenges encountered in PDF data extraction, shedding light on why what may seem like a simple task can often become quite complex. Manual PDF text extraction requires meticulous attention to detail, making it a time-consuming endeavor. A slight error can lead to inefficiencies and potential errors. Human errors are common in manual extraction, potentially impacting the accuracy of the extracted data. Unlike other document formats like DOC, XLS, or CSV, editing PDF data is not straightforward, hindering customization according to specific requirements. Extracting data from tables in PDFs often results in the loss of original formatting, making it challenging to maintain data integrity. How to Extract Data from PDF Files in 2024: Extracting data from PDFs used to be a lot of work when the technology hadn’t advanced back in the days. However, now, with the advent of AI, OCR, and NLP, you don’t have to spend hours on manually extracting the data. All you need is an efficient tool like Algodocs that does the job for you accurately and easily.

Categories Data Extraction PDF Tags ai platform for data extraction algodocs character recognition data extraction from images deep learning export extracted data to excel invoice process machine learning ocr api web-based ai platform for data extraction By Shubhankar Biswas Published October 13, 2025, 12:03 Updated July 29, 2026, 02:32 A PDF Parser is a program or a library that enables end-users and organizations to parse data from native PDF documents. Often, organizations need to parse PDF documents for specific fields such as Account Number, Date, Address, Bill to/from information, or parse tabular data. PDF Parsers are usually needed and used for processing and parsing data from large amounts of documents. On the other hand, when you have a handful of documents you simply go and copy the data you need from PDF documents manually and paste it to Excel or anywhere you need it to be. PDF Parsers enable end-users to get data from hundreds and thousands of PDF documents in real time by saving huge amounts of time and, thus, money. Parsing pdf documents isn’t an easy task. There are various ways native pdf documents are generated and parsing data from such pdf documents requires smart approaches. Parsed data from PDF documents greatly varies depending on the industry, which means the data parsed might also greatly change, which complicates the task. Parsing PDF medical forms, which contain specific fields such as First, Middle, and Last names, Sex, Date of Birth, etc. are very different from PDF purchase orders that contain mainly the items in the tabular form with such columns as Item No, Code, Quantity, Item Price, Amount, etc. Therefore, if PDF Parser produces just a bunch of text from a PDF document it does not make much sense for the end-user. What end-users or organizations require is the structured data parsed from PDF documents. In other words, PDF Parser should extract from PDF documents only the data the end-user needs and in the right structured format. For this, the PDF Parser must be smart and flexible enough to parse PDF documents with various layouts and data types. How to parse PDF documents with various layouts? Algodocs allows you to parse PDF documents of any complexity in their layouts and type of data. With the flexible extracting rules of Algodocs, you can parse data from PDFs with different layouts.

Purchase orders, Invoices, Agreements, and many more document types are interchanged in PDF formats. On the other hand, JSON is another format that represents data in a structured format, which is widely used in transferring data between web applications. As a result, Working with JSON is much easier than with PDF. Therefore, in this article, we will talk about PDF and JSON formats and how you can convert your PDF documents to JSON format. What is a PDF? PDF (Portable Document Format) was initially developed by Adobe® Systems in 1992 and is standardized as ISO 32000. What makes PDF so popular is it is independent of the application software, hardware, and operating system. Other than text and images PDF files may contain a variety of content such as annotations, form fields, layers, etc. There are many advantages of PDF format such as multi-dimensionality, which we have already mentioned – being able to contain various types of content, text, images, videos, vector graphics, interactive fields, hyperlinks, and buttons. Moreover, PDF documents are easily created and viewed on different devices. Security in PDF was one of the primary concerns of Adobe® Systems. Therefore, PDFs have different access levels to protect the content and the whole document, such as passwords, digital signatures, and watermarks. However, some of the downsides of a PDF are the complexity of editing and especially extracting data from it. Moreover, PDFs are not generated in the same way, so different PDF files can be created in various ways, which complicates the task of extracting data from PDF documents. What is a JSON? JSON (JavaScript Object Notation) is a very popular data format, which appeared in the early 2000s. JSON is a language-independent data format and is used to transfer data between software applications, particularly web applications, usually between server and client. Most of the API integrations are realized using JSON format for data transfer since it is very easy to work with JSON. Consider a JSON object called person, which contains the following information:{ “name”: “John”, “surname”: “Doe”, “age”: 25} Accessing fields of a JSON object is as simple as using the name of the object and the field name you want to access by separating them with a dot as follows: To access a person’s name we use person.name, which will give us “John” as a result. Similarly, we do for surname and age fields: person.surname, person.age Note how easy it is to access any field of a JSON object, which is definitely not compared to accessing specific information in the PDF document. How does JSON differ from PDF? Although PDF and JSON are both widely spread and used, there is a huge difference between PDF and JSON. The difference between them is simply in the purpose of their usage. PDF is mainly used for exchanging information between humans, since it contains text, graphics, illustrations such as images and videos, etc. On the other hand, JSON is mainly used between computer programs and different applications for communicating and exchanging data between each other. It is not an easy task for a human to read information from a JSON file, especially if it is a compressed one, but it is a perfect way to access information from JSON for a software application. The opposite goes for the PDF. Therefore, PDF and JSON become important, useful, and helpful only when they are used in the right place and for the right purpose. How to Convert PDF to JSON? Often, organizations need to transfer data to other programs for further processing. This data is often stored in PDF documents since businesses often speak to each other in a “PDF language”. However, extracting information from PDF documents can be challenging. The simplest solution is that you can always copy and paste text from a PDF and send it to where it belongs. However, this simple approach has many problems, since first of all this will work only with native PDF files (not scans) for which you can even use some free PDF Parsers. Another problem even if your PDF documents are all native, it is not easy to copy the entire table from a PDF by maintaining its format, especially if the table spans over multiple pages, for example, 100 or 1000 pages. Additionally, often organizations need to extract specific data from PDFs, for example not the entire table, but instead specific rows or columns based on some conditions. Last, but not least, it is not worth spending your valuable time on menial data entry! Convert PDF documents to JSON with Algodocs Algodocs offers a perfect solution to extract any type of data from PDF documents and transfer it to other programs in real-time. Algodocs can extract fields and tables of any complexity from native as well as scanned PDF documents. You can convert your PDF documents to JSON in three steps with Algodocs. First, start by creating an extractor in Algodocs. Algodocs has some preprocessing operations that take some time depending on the number of pages your PDF document contains; usually, it is around 15-20 seconds. Then, go to the ‘Extracting Rules’ editor to create your extracting rules for every field you need to extract from your PDF documents. Similarly, if you need to extract tables from your PDF documents you can create extracting rules for tables by selecting ‘Table’ as the data type. After you are done with creating and extracting rules,

Even when the documents are computer-generated PDFs, it can still be a complex and annoying task, since copying a tabular text from a PDF and pasting it to an Excel spreadsheet is not always as simple as it may look. Moreover, manual data entry with human interaction involves errors in addition to wasting time. How to convert PDF or scanned tables to Excel spreadsheets? There are free online tools that you can use to convert PDF tables to Excel spreadsheets if the PDF document is a text document (not scanned). Even for system-generated PDF documents, those tools just convert a table to Excel as is, without letting you filter a table and convert it into the format you need. Especially when tables span over multiple pages of a PDF, you definitely need to trim out all unnecessary text that occurs between pages, like footer and header information. Moreover, sometimes you might need to filter out either some rows or even columns of a table itself. Imagine table extraction from scanned documents! What if those scanned documents are of low quality? Alternatively, even worse, what if those documents are images taken by a mobile device… Yes, then the task of extracting a table from such documents gets even harder… Algodocs comes to the rescue!

Categories PDF Tags data extraction from images By Shubhankar Biswas Published February 28, 2025, 08:52 Updated July 20, 2026, 08:20 We are all familiar with PDFs—an essential document format used for sharing textual data. However, extracting data from a PDF can be a challenging task due to the way information is stored within the file. There are two primary types of PDFs: native PDFs, which are usually editable, and scanned PDFs, which contain images of documents saved as PDF files. Both types are widely used in professional and personal settings. You may have a 50-page document of important notes or receive a 1,000-page scanned report from your manager. Extracting data from these two types of PDFs requires different approaches. Native PDFs are easier to process, while scanned PDFs need advanced OCR and AI capabilities for accurate and efficient data extraction. That’s why we’ll explore how to use the powerful LLM model, ChatGPT, to extract data from PDFs. Additionally, we’ll discuss how AlgoDocs AI provides a more precise and efficient solution for handling both types of PDFs. What You Need to Know Before Starting Before diving into PDF data extraction with ChatGPT, it’s essential to understand the basics. PDFs can vary greatly—some contain plain text that is easy to extract, while others have scanned images, complex tables, or charts that require extra processing. Knowing the type of PDF you’re working with is the first step. ChatGPT, developed by OpenAI, is excellent at processing text but does not directly read PDFs. You need to convert the PDF content into a format it can handle, such as plain text. What You’ll Need: A PDF file A tool to convert the PDF to text (if it’s not already editable) Examples: AlgoDocs AI, Adobe Acrobat, or free online converters Access to ChatGPT (via the web interface or API) Clear instructions for ChatGPT to process the extracted text Understanding these essentials will make the PDF data extraction process smoother and more efficient. Step-by-Step Guide to Extract PDF Data with ChatGPT Now, let’s break down the process into five simple steps that anyone can follow, even without technical expertise. Step 1: Preparing Your PDF File Ensure that your PDF is ready for extraction. If it’s a native text-based PDF, it’s good to go. If it’s a scanned document or an image-based file, use AlgoDocs AI or Adobe Acrobat to convert it into an editable format. While ChatGPT can process scanned PDFs, it may struggle with blurry or unstructured data, leading to errors or inaccurate results. Step 2: Feeding Data into ChatGPT Once you have extracted the text, open ChatGPT and paste it into the chat box. However, don’t just drop the text in without guidance. Provide ChatGPT with clear instructions. For example: “Extract all the dates from this text and list them.” “Identify the item names and prices in this invoice.” If you have a simple PDF and need full data extraction, you can use a straightforward command like: “Extract all data from this PDF.” This method works well for small-scale extractions but may become difficult when dealing with large datasets. Step 3: Structuring and Extracting Insights ChatGPT will process your request and present the extracted data. If the output is unorganized, refine your prompt: “Sort the extracted dates in chronological order.” “Format the item list into a table.” “Summarize the extracted data.” By tweaking your queries, you can refine the results for better readability and usability. Step 4: Troubleshooting Common Issues If ChatGPT misses data or produces inconsistent results, consider: Checking if the text extraction process introduced errors. Adjusting your prompt to be more specific. Cleaning up the extracted text manually before feeding it into ChatGPT. Step 5: Improving Your Extraction Results For more effective results: Use high-quality OCR tools like AlgoDocs or any online pdf tools for scanned PDFs. Break down complex PDFs into sections (e.g., extract tables separately from narrative text). Use precise prompts to minimize errors (e.g., “Extract all email addresses from this text”). Limitations of Using ChatGPT for PDF Extraction While ChatGPT is powerful, it has limitations: Cannot directly read PDFs – requires conversion. Struggles with complex data – such as tables and handwritten notes. Does not store session data – meaning you cannot reference previous extractions. These limitations highlight why ChatGPT is best for quick extractions rather than large-scale automated tasks. Why AlgoDocs AI Outshines ChatGPT for PDF Data Extraction For more advanced PDF extractions, AlgoDocs AI offers several advantages over ChatGPT: Directly processes PDFs – No need for conversion. Handles structured data effectively – Ideal for tables, invoices, and forms. Works efficiently on large volumes – Extracts data from multiple PDFs simultaneously. Integrates with third party apps – Streamlining workflow automation. For instance, if you’re processing invoices, ChatGPT might only extract limited structured data, while AlgoDocs AI allows you to extract invoice numbers, item lists, and totals accurately. Conclusion Extracting PDF data with ChatGPT is a useful skill for handling small projects efficiently. By converting PDFs to text and providing clear instructions, you can extract valuable insights. However, ChatGPT has its limitations, especially with scanned and complex PDFs. For more precise and large-scale extraction, AlgoDocs AI provides a faster and more reliable alternative. Whether you choose ChatGPT or AlgoDocs, mastering PDF data extraction can save time and enhance productivity.
