            Python Library Camelot not reading all tables in one page
            Asked 2022-Apr-01 at 08:14

            I'm using Camelot Python Library to read all tables in a page of pdf document

            I'm tring to read all tables at page 10 in this pdf

            I tried to debug plotting the page and I noticed something if I change the flavor:

            This is with flavor lattice

            This is with flavor stream

            The problem is if I use lattice flavor it will not read properly the tables an example here

            If I use flavor='stream', It will read data properly but just of one table: The output is somenthing like this.

            I tried to use table_area/table_regions for detect the two tables with flavor='stream', but it didn't work. I paste the code down here.

            Code with lattice:



            Answered 2022-Apr-01 at 08:14

            The problem is that you are using table_area instead of the correct parameter table_areas (read the docs).

            The following command works perfectly:

            tables = camelot.read_pdf(file,pages='10', flavor='stream', edge_tool=1500, table_areas=['10,450,550,50','10,750,550,450'])

            Difference between table_areas and table_regions

            table_areas should be used when you know the exact position of the table. Conversely, table_regions makes the detection engine look for tables only in those generic page regions.



            How to change the final type after reduction of a downstream collector in a Java 8 stream?
            Asked 2022-Jan-26 at 15:16

            I got a legacy application using data structures like those in the following toy snippet and I can't easily change these data structures.

            I use a Java 8 (only) stream to do some stats and I failed to get the wished type using Collectors.

            You can use Collectors.collectingAndThen to convert the reduced double value to a corresponding String:



            Camelot not detecting table within table
            Asked 2021-Dec-25 at 11:17

            I have observed that camelot is not detecting nested tables in the sample document I have. In the image attached, I'm getting only one table extracted as whole. Is there anyway using which we can detect the inner tables as well?



            Answered 2021-Dec-25 at 11:17

            To programmatically extract internal tables only, you can try passing table_regions parameter, specifying a fixed limited part of the page.

            When table_regions is specified, Camelot will only analyze the specified regions to look for tables.



            How to move a character to another column in the same row in a pandas dataframe
            Asked 2021-Dec-18 at 16:25

            I got stuck trying to clean a dataframe similar to this one:

            code course name EOS Mid test AA101 Course 1 350 420 NaN AA102 Course 2 400 470 NaN AB101 Course 3 #560 570 NaN AB102 Course 4 410 465 NaN AC101 Course 5 # 522 NaN

            I need to keep only numerical values in the column EOS and move # characters that appear in it to the column test, to indicate that an additional test is required for that course. This is because some of the values have a # before the actual number, such as Course 3, and some have only the # as the value, such as Course 5.

            The dataframe was created using Camelot to extract those values from a PDF table.

            What I need is to take this # out of this column and add it to the test column instead.

            Is there an easy way to do that?

            How to extract all arrays in a pdf?
            Asked 2021-Nov-18 at 14:01

            Is there a way to extract data from every arrays in a pdf using python?

            I've tested tabula, camelot, pdfplumber but none can extract everything or correctly.

            An example:

            I would like to work on these using matrix, dataframe, ...

            Should I opt for OCR for better recognition ?

            EDIT :

            I am trying to retrieve this table from a pdf using tabula-py.

            In my opinion, Camelot gets a good result using stream flavor.



            Concat multiple small DataFrames as one big DataFrame
            Asked 2021-Nov-09 at 21:38

            I'm trying to make a large DataFrame from a bunch of smaller DF. so I've look at multiple sites a nd they all mention to use the pd.concat() method and create an empty DataFrame. I did, however when I print inside my for loop I still get data as if it was still sectioned by individual DataFrame, and when i print my (now supposedly filled DataFrame ) I get an empty DF.

            Note: All tables have the same structure

            Camelot dependencies - pandas required?
            Asked 2021-Nov-09 at 14:24

            Good morning,

            I'm in the process of getting Camelot approved for use in my office to help with some projects but need a complete list of dependencies to provide before install.

            Camelot only lists Tkinter and Ghostscript as dependencies, but mentions the use of pandas data frames, which to my understanding is a separate module that would also be required.

            Could someone help me understand how pandas fits into Camelot-py?

            Is it built into Camelot? Or would I be required to request pandas to be installed as well?

            Thank you for your help.



            Answered 2021-Nov-09 at 14:24

            pandas is installed separately when Camelot-py is installed using pip. Here is full list of modules pip installed when running pip install "camelot-py[base]" on Python 3.8 in a 64-bit Windows machine.

            To correctly extract tables from the second file, it is necessary to process background lines, using the appropriate parameter (process_background) for lattice method, as you can see in the following code:

            I have two pdf documents, both in same layout with different information. The problem is: I can read one perfectly but the other one the data is unrecognizable.

            The problem: malformed PDF

            Simply, the problem is that your second PDF is malformed / corrupted. It doesn't contain correct font information, so it is impossible to extract text from your PDF as is. It is a known and difficult problem (see this question).

            You can check this by trying to open the PDF with Google Docs.

            Google Docs tries to extract the text and this is the result:.

            Possible solutions

            If you want to extract the text, you can print the document to an image-based PDF and perform an OCR text extraction. However, Camelot does not currently support image-based PDFs, so it is not possible to extract the table.

            If you have no way to recover a well-formed PDF, you could try this strategy:

            • print PDF to an image-based PDF
            • add a good text layer to your image-based PDF (using OCRmyPDF)
            • try using Camelot to extract tables



            How to feed ghostscript DLL library to python in Windows?
            Asked 2021-Sep-05 at 16:19

            Background. I'd like to use camelot.read_pdf(file) which uses ghostscript.

            1. The project has ghostscript package.
            2. Windows 10 got installed Ghostscript 9.54.0 for Windows (64 bit). 2.1. c:\Program Files\gs\gs9.54.0\bin has been added to system PATH env variable.
            3. Python 3.9 64 bit.

            The required library path is c:\Program Files\gs\gs9.54.0\bin\gsdll64.dll.
            But python does not “see” it. As it's, probably, not loaded in the system.



            Answered 2021-Sep-05 at 16:19


            First, Python can find DLL by paths from environment PATH variable. So, the path c:\Program Files\gs\gs9.54.0\bin has to be presented there.

            PyCharm (or another IDE) has to be reloaded (that's my main mistake).

            Thanks @Petesh to the comment.
