I need to extract tables from pdf, these tables can be of any type, multiple headers, vertical headers, horizontal header etc. I have implemented the basic use cases for both and found tabula doin...
I came across a great library called Tabula and it almost did the trick. Unfortunately, there is a lot of useless area on the first page that I don't want Tabula to extract. According to documentat...
Tabula needs areas to be specified in PDF units, which are defined to be 1/72 of an inch. If using Acrobat Reader DC, you can use the Measure tool and multiply its readings by 72. Tabula needs the area to be specified as the top, left, bottom and right distances. To obtain them, you can measure the distances from the top of the page to the beginning of the table and so on.
from tabula import convert_into convert_into("Ativos_Fevereiro_2018_servidores_rj.pdf", "test_s.csv", output_format="csv") Please, does anyone know of another method to use tabula-py for this type of demand? Or another way to convert PDF to CSV in this file type?
If you accidentally installed tabula before installing tabula-py, they'll conflict in the namespace (even after uninstalling tabula). Uninstall tabula-py and re-install it.
For each page of the file, it was necessary to define into tabula's read_pdf function the area of the table and the limits of the columns. Here is the working code:

2 I have a pdf file with tables in it and would like to read it as a dataframe using tabula. But only the first PDF page has column header. The headers of dataframes after page 1 becomes the first row on information. Is there any way that I can add the header from page 1 dataframe to the rest of the dataframes? Thanks in advance. Much appreciated!
from tabula import read_pdf df = read_pdf(r"C:\Users\Himanshu Poddar\Desktop\pdf_file.pdf") But if there is more than one table present in a PDF file I am unable to extract those tables because it's only extracting the first one.
Without any knowledge about Tabula, it seems that the Python module is trying to capture the output from a Java program. What happens if you run the Java Tabula module directly? Doesn't Java typically use UTF-16 (or even the obsolescent UCS-2)?
