The PDFs contained records of his financial transactions over a period of years and he wanted to analyze them.Unfortunately, Excel and plain text versions of the files were no longer available, so the PDFs were his only option.I extracted the data my friend needed and sent it to him in CSV format so he could analyze it with the program of his choice.
Tika was so fast and easy to use that I really enjoyed the experience. I enjoyed it so much I decided to write a blog post about parsing PDFs with Tika. ![]() Apache Tika Disable Tesseract How To Parse DataGovernments also provide data in PDF format, so I decided it would be helpful to demonstrate how to parse data from PDFs available on a government website. This way, with these two blog posts, you have examples of acquiring government data, even if its embedded in HTML or PDFs. For this post, lets extract the data on expenditures by agency and revenue sources. In the 2015-16 Budget PDF, the titles for these two tables are. As youd expect based on the name of the key, its key-value pairs provide metadata about the parsed PDF. The script will iterate over the PDF files in a folder and, for each one, parse the text from the file, select the lines of text associated with the expenditures by agency and revenue sources tables, convert each of these selected lines of text into a Pandas DataFrame, display the DataFrame, and create and save a horizontal bar plot of the totals column for the expenditures and revenues. So, after you run this script, youll have six new plots, one for revenues and one for expenditures for each of the three PDF files, in the folder in which you ran the script. Then you can run the script on the command line with the following command. Apache Tika Disable Tesseract Code Because WeI created the two functions to avoid duplicating code because we perform these operations twice for each file, once for revenues and once for expenditures. We use a for loop to iterate over the PDFs and for each one we extract the lines of text we care about, convert the text into a Pandas DataFrame, display some of the DataFrames information, and save plots of the total values in the revenues and expenditures tables. As my friends experience illustrates, there may be other situations in which you need to extract data from PDFs. With Tika, PDFs become another rich source of data for your analysis. It helps me a lot. ![]() Apache Tika Disable Tesseract Download Plain TextIs there a way to get the same result as Apache Tika Client, download plain text in python script. ![]()
