![]() ![]() Then we will use the same procedure to extract data from all the bounding boxes of pdf. Therefore, these terms would be used interchangeably.įirst, we will extract text from one of the bounding boxes. Please note that in our case the bounding box, annots, and rectangles are the same thing. Ex – ash, 23, 2, 3.Īnnots: An annotation associates an object such as a note, image, or bounding box with a location on a page of a PDF document, or provides a way to interact with the user using the mouse and keyboard. Word: Sequence of characters without space. However, none of them worked except PyMuPDF to extract data from PDF using Python.īefore going into the code it’s important to understand the meaning of 2 important terms which would help in understanding the code. I have tried many python libraries like PyPDF2, PDFMiner, pikepdf, Camelot, and tabulat. Here are the PDF and the red bounding boxes from which we need to extract data. Now, I will show you how I extracted data from the bounding boxes in a PDF with several pages. This library provided many applications such as extracting images from PDF, extracting texts from different shapes, making annotations, draw a bounded box around the texts along with the features of libraries like PyPDF2. ![]() I have used the PyMuPDF library for this purpose. Here, I will show you a most successful technique & a python library through which you can extract data from bounding boxes in unstructured PDFs and then performing data cleaning operation on extracted data and converting it to a structured form. To analyze unstructured data, we need to convert it to a structured form.Īs such, there is no specific technique or procedure for extracting data from unstructured PDFs since data is stored randomly & it depends on what type of data you want to extract from PDF. ![]() In this case, it is not feasible to use the above python libraries since they will give ambiguous results. However, in the real world, most of the data is not present in any of the forms & there is no order of data. In all these cases data is in structured form i.e. You can also extract tables in PDFs through the Camelot library. For example, you can use the PyPDF2library for extracting text from PDFs where text is in a sequential or formatted manner i.e. There are a couple of Python libraries using which you can extract data from PDFs. Although in some files, data can be extracted easily as in CSV, while in files like unstructured PDFs we have to perform additional tasks to extract data from PDF Python. This article was published as a part of the Data Science Blogathon Introduction:ĭata Extraction is the process of extracting data from various sources such as CSV files, web, PDF, etc. ![]()
