This post will go through a few ways of scraping tables from PDFs with Python. To learn more about scraping tables and other data from PDFs with R, click here. Note, this options will only work for PDFs that are typed – not scanned-in images.
tabula-py
tabula-py is a very nice package that allows you to both scrape PDFs, as well as convert PDFs directly into CSV files. tabula-py can be installed using pip:
If you have issues with installation, check this. Once installed, tabula-py is straightforward to use. Below we use it scrape all the tables from a paper on classification regarding the Iris dataset (available here).
The result stored into tables is a list of data frames which correspond to all the tables found in the PDF file. To search for all the tables in a file you have to specify the parameters page = 'all' and multiple_tables = True.
You can also use tabula-py to convert a PDF file directly into a CSV. The first line below will find the first table in the PDF and output it to a CSV. If we add the parameter all = True, we can write all of the PDF's tables to the CSV.
tabula-py can also scrape all of the PDFs in a directory in just one line of code, and drop the tables from each into CSV files.
We can perform the same operation, except drop the files out to JSON instead, like below.
Camelot
Camelot is another possibility for scraping tables from PDFs. Camelot can be installed like so:
Camelot does have some additional dependencies, including GhostScript, which are listed here. Once installed, we can use Camelot similarly to tabula-py to scrape PDF tables.
This returns a TableList object. To access any of the tables found by index, you can do this:
One cool feature of Camelot is that you also get a 'parsing report' for each table giving an accuracy metric, the page the table was found on, and the percentage of whitespace present in the table.
From here we can see that the 0th-indexed identified table is essentially whitespace. If we look at the raw PDF, we can see there's not a table on that page, so it's safe to ignore this empty data frame.
Like tabula-py, you can export all the scraped tables to a file. Camelot supports (as of this writing) CSV, JSON, HTML, and SQLite. If you choose CSV, Camelot will create a separate CSV file for each table by default. You can create a zip file of these CSVs by adding the parameter compress = True. Choosing to export to excel will create a single workbook containing an individual worksheet for each table.
If you want to export just a single table, you can do it just like in pandas since each individual table can be referred to as a data frame object.
Excalibur
How to get minecraft on my laptop. If you're looking for a web interface to use for extracting PDF tables, you can check out Excalibur, which is built on top of Camelot.
If Camelot is already installed, you can just use pip to install Excalibur:
You can get started with Excalibur from the command line. After you open the command line, just type the following:
The above command will initialize a meta database needed for the application. Next, run the below command to start the web server via Flask:
If you open a web browser to your local host, you should see an interface like below.
From here, you'll be able to upload a PDF file of your choice, and Excalibur will do the rest.

Problem
How To Open Pages File
When opening a PDF document a page, other than the first page, is displayed as the default page.
For example a PDF document with three pages would open on the second page.
Solution
I've seen this issue when a page has been inserted into an existing PDF document, for example a two page PDF had another page inserted as the first page.
The PDF file itself has a setting for the default page when the PDF document is opened. By default this is set to page one – however when a new page is inserted as page one this changes to page two. How can i download powerpoint.
To fix you will need to open the PDF document in Adobe Acrobat (the PDF creating/editing software) and change the default page using the steps below.
How To Open Pdf In Pages
- With the PDF document open in Adobe Acrobat
- Click on the ‘File' menu and then ‘Properties'
- Open the ‘Initial View' tab
- Under ‘Open to page:' change to ‘1'
- Click ‘OK' to save the changes.
