The code above is written against an old version of the API, see my comment below. Pdfminer is an invaluable tool for pdf-scraping.įrom pdflib.page import TextItem, TextConverterįrom pdflib.pdfparser import PDFDocument, PDFParserįrom pdflib.pdfinterp import PDFResourceManager, PDFPageInterpreterĭevice = CsvConverter(rsrc, outfp, "ascii") Other tools I tried include pdftotext, ps2ascii and the online tool. Using this approach, I was able to extract text from a pdf that no other tool was able to extract content suitable for further parsing from. The function simply sorts the TextItem content objects according to their y and x coordinates, and outputs items with the same y coordinate as one text line, separating the objects on the same line with ' ' characters.
I did this to convert pdf contents to semi-colon separated text, using the code below. You have access to the pdf's content model, and can create your own text extraction. You can also quite easily use pdfminer as a library. See below code that works for Python 3: import sys # Process each page contained in the document. Interpreter = PDFPageInterpreter(rsrcmgr, device) This will work for those who are getting import errors with process_pdf import sysįrom nverter import XMLConverter, HTMLConverter, TextConverterĭevice = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams) Since none for these solutions support the latest version of PDFMiner I wrote a simple solution that will return text of a pdf using PDFMiner. Line = child._text.encode(dec) #<- changedĭevice = CsvConverter(rsrc, outfp, codec="utf-8", laparams=LAParams()) Updated for version 20110515 (thanks to Oeufcoque Penteano!): def pdf_to_csv(filename):įrom nverter import LTChar, TextConverterįor child in self.cur_item._objs: #<- changed If isinstance(child, LTChar): #<- changedĭevice = CsvConverter(rsrc, outfp, codec="utf-8", laparams=LAParams()) #<- changed def pdf_to_csv(filename):įrom nverter import LTChar, TextConverter #<- changed In short I replaced LTTextItem with LTChar and passed an instance of LAParams to the CsvConverter constructor.
#Python convert pdf to text update
Here is an update for the latest version in pypi, 20100619p1. Interpreter = PDFPageInterpreter(rsrc, device)įor i, page in enumerate(doc.get_pages()): # becuase my test documents are utf-8 (note: utf-8 is the default codec) # convert() function in the pdfminer/tools/pdf2text moduleĭevice = CsvConverter(rsrc, outfp, codec="utf-8") #<- changed the following part of the code is a remix of the (" ".join(line for x in sorted(line.keys()))) TextConverter._init_(self, *args, **kwargs)
Here's the updated version (with comments on what I changed/added): def pdf_to_csv(filename):įrom cStringIO import StringIO #<- added so you can copy/paste this to try itįrom nverter import LTTextItem, TextConverterįrom pdfminer.pdfparser import PDFDocument, PDFParserįrom pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter You can check the version you have installed with the following: > import pdfminer PDFMiner has been updated again in version 20100213 The PDFMiner package has changed since codeape posted.
