Deprecation Note: This is the old version of the Tabula extraction engine. New projects wishing to integrate Tabula should use tabula-java (the new Java version of this extraction engine) unless you prefer to use JRuby. Users looking for the command-line version of Tabula should also use tabula-java.
Extract tables from PDF files. tabula-extractor is the table extraction engine that used to power Tabula.
If you're beginning a new project, consider using tabula-java, a pure-Java version of the extraction engine behind Tabula. If you want Ruby bindings and are okay using JRuby (or have already begin a project), you may continue to use this project. This project's JRuby backend has been replaced with the Java backend; all that remains here is a thin wrapper for Ruby compatibility. This wrapper maintains API backwards-compatibility with the old, pure-JRuby implementation that we all know and love.
tabula-extractor only works with JRuby 1.7 or newer. Install JRuby and run
jruby -S gem install tabula-extractor

tabula-extractor is a RubyGem that you can use to programmatically extract tabular data, using the Tabula engine, in your scripts or applications. We don't have docs yet, but the tests are a good source of information.
Here's a very basic example:
require 'tabula'
pdf_file_path = "whatever.pdf"
outfilename = "whatever.csv"
out = open(outfilename, 'w')
extractor = Tabula::Extraction::ObjectExtractor.new(pdf_file_path, :all )
extractor.extract.each do |pdf_page|
pdf_page.spreadsheets.each do |spreadsheet|
out << spreadsheet.to_csv
out << "\n\n"
end
end
out.close
