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:...

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

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.
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
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?...

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

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....
ANSWERAnswered 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.
This is an example which I can read perfectly, download here:...

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).
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
Background. I'd like to use
camelot.read_pdf(file) which uses ghostscript.
- The project has
- Windows 10 got installed Ghostscript 9.54.0 for Windows (64 bit).
c:\Program Files\gs\gs9.54.0\binhas been added to system
- Python 3.9 64 bit.
The required library path is
But python does not “see” it. As it's, probably, not loaded in the system.
ANSWERAnswered 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.
