If you choose CSV, Camelot will create a separate CSV file for each table by default. Camelot supports (as of this writing) CSV, JSON, HTML, and SQLite. Like tabula-py, you can export all the scraped tables to a file. 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.

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.įrom here we can see that the 0th-indexed identified table is essentially whitespace. To access any of the tables found by index, you can do this: Tables = camelot.read_pdf(file, pages = '1-end') Once installed, we can use Camelot similarly to tabula-py to scrape PDF tables. Camelot can be installed like so:Ĭamelot does have some additional dependencies, including GhostScript, which are listed here. nvert_into_by_batch('/path/to/files', output_format = 'json', pages = 'all')Ĭamelot is another possibility for scraping tables from PDFs. We can perform the same operation, except drop the files out to JSON instead, like below. nvert_into_by_batch('/path/to/files', output_format = 'csv', pages = 'all') 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. nvert_into(file, 'iris_all.csv', all = True) # output all the tables in the PDF to a CSV # output just the first table in the PDF to a CSV

If we add the parameter all = True, we can write all of the PDF’s tables to the CSV. The first line below will find the first table in the PDF and output it to a CSV. You can also use tabula-py to convert a PDF file directly into a CSV. To search for all the tables in a file you have to specify the parameters page = “all” and multiple_tables = True. The result stored into tables is a list of data frames which correspond to all the tables found in the PDF file. Tables = tabula.read_pdf(file, pages = 'all', multiple_tables = True) Below we use it scrape all the tables from a paper on classification regarding the Iris dataset ( available here). Once installed, tabula-py is straightforward to use. If you have issues with installation, check this. Tabula-py is a very nice package that allows you to both scrape PDFs, as well as convert PDFs directly into CSV files. Note, this options will only work for PDFs that are typed – not scanned-in images. To learn more about scraping tables and other data from PDFs with R, click here.
