Tabula

Tabula helps you liberate data tables trapped inside PDF files.

Why Tabula?

If you’ve ever tried to do anything with data provided to you in PDFs, you know how painful this is — you can’t easily copy-and-paste rows of data out of PDF files. Tabula allows you to extract that data in CSV format, through a simple web interface (Check out this short screencast)

Caveat: Tabula only works on text-based PDFs, not scanned documents. If you can click-and-drag to select text in your table in a PDF viewer (even if the output is disorganized trash), then your PDF is text-based and Tabula should work.

Security Concerns?: Tabula is designed with security in mind. Your PDF and the extracted data never touch the net -- when you use Tabula, as long as your browser's URL bar says "localhost" or "127.0.0.1", all processing takes place on your local machine. Tabula does download a list of Tabula versions from our server to alert you if Tabula has been updated (and we use hits to that list to count how often Tabula is being used); it also downloads a few badges and assets from the web.

Using Tabula

First, make sure you have a recent copy of Java installed. You can download Java here. Tabula requires a Java Runtime Environment compatible with Java 6 or Java 7. If you have a problem, check Known Issues first, then report an issue.

Windows

Download tabula-win.zip from the download site. Unzip the whole thing and open the tabula.exe file inside. A browser should automatically open to http://127.0.0.1:8080/ . If not, open your web browser of choice and visit that link.

To close Tabula, just go back to the console window and press "Control-C" (as if to copy).

If you need Tabula to use a port other than 8080, set the TABULA_PORT environment variable.
###Mac OS X Download tabula-mac.zip from the download site. Unzip and open the Tabula app inside. A browser should automatically open to http://127.0.0.1:8080/ . If not, open your web browser of choice and visit that link.

To close Tabula, find the Tabula icon in your dock, right-click (or control-click) on it, and press "Quit".

Note: If you’re running Mac OS X 10.8 or later, you might get an error like "Tabula is damaged and can't be opened." We're working on fixing this, but click here for a workaround.
###Other platforms (e.g. Linux) Download tabula-jar.zip from the download site and unzip it to the directory of your choice. Open a terminal window, and cd to inside the tabula directory you just unzipped. Then run:

java -Dfile.encoding=utf-8 -Xms256M -Xmx1024M -jar tabula.jar

If the program fails to run, double-check that you have Java installed and then try again.

Tabula binds to port 8080 by default. You can change it with the jetty.port property:

java -Dfile.encoding=utf-8 -Xms256M -Xmx1024M -Djetty.port=9999 -jar tabula.jar

Known issues

There are some bugs that we're aware of that we haven't managed to fix yet. If there's not a solution here or you need more help, please go ahead and report an issue.

Legacy Java Environment (SE 6) Is Required: (Mac): The Mac operating system recently changed how it packages the Java Runtime Environment. If you get this error, download Tabula's "large experimental" package. This package includes its own Java Runtime Environment and should work without this issue.
"Tabula is damaged and can't be opened" (Mac): If you’re running Mac OS X 10.8 or later, GateKeeper may prevent you from opening the Tabula app. Please see this GateKeeper page for more information.
1. Right-click on Tabula.app and select Open from the context menu.
2. The system will tell you that the application is "from an unidentified developer" and ask you whether you want to open it. Click Open to allow the application to run. The system remembers this choice and won't prompt you again.
(If you continue to have issues, double-check the OS X GateKeeper documentation for more information.)

org.jruby.exceptions.RaiseException: (Encoding::CompatibilityError) incompatible character encodings: (Windows): Your Windows computer expects a type of encoding other than Unicode or Windows's English encoding. You can fix this by entering a few simple commands in the Command Prompt. (The commands won't affect anything besides Tabula.)
1. Open a Command Prompt
2. type cd and then the path to the directory that contains tabula.exe, e.g. cd C:\Users\Username\Downloads
3. Change that terminal's codepage to Unicode by typing: chcp 65001
4. Run Tabula by typing tabula.exe
A browser tab opens, but something other than Tabula loads there. Or Tabula doesn't start. It's possible another program is using port 8080, whichh Tabula binds to by default. You can try closing the other program, or change the port Tabula uses by running Tabula from the terminal with the jetty.port property:

java -Dfile.encoding=utf-8 -Xms256M -Xmx1024M -Djetty.port=9999 -jar tabula.jar

Running Tabula from source (for developers)

Download JRuby. You can install it from its website, or using tools like rvm or rbenv

Download Tabula and install the Ruby dependencies. (Note: if using rvm or rbenv, ensure that JRuby is being used.

git clone git://github.com/jazzido/tabula.git
cd tabula

gem install bundler
gem install tabula-extractor
bundle install

Then, start the development server:

bundle exec rackup

(If you get encoding errors, set the JAVA_OPTS environment variable to -Dfile.encoding=utf-8)

The site instance should now be viewable at http://127.0.0.1:9292/ .

You can a couple some options when executing the server in this manner:

TABULA_DATA_DIR="/tmp/tabula" \
TABULA_DEBUG=1 \
bundle exec rackup

TABULA_DATA_DIR controls where uploaded data for Tabula is stored. By default, data is stored in the OS-dependent application data directory for the current user. (similar to: C:\Users\foo\AppData\Roaming\Tabula on Windows, ~/Library/Application Support/Tabula on Mac, ~/.tabula on Linux/UNIX)
TABULA_DEBUG prints out extra status data when PDF files are being processed. (false by default.)

Alternatively, running the server as a JAR file

Testing in this manner will be closer to testing the "packaged application" version of the app.

bundle exec rake war
java -Dfile.encoding=utf-8 -Xms256M -Xmx1024M -jar build/tabula.jar

Building a packaged application version

After performing the above steps ("Running Tabula from source"), you can compile Tabula into a standalone application:

Mac OS X

If you wish to share Tabula with other machines, you will need a codesigning certificate. Our distribution of Tabula uses a self-signed certificate, as noted above. See this section of build.xml for details. If you will only be running Tabula on the machine you are building it on, you may remove this entire block (lines 44-53).

To compile the app:

rake macosx

This will result in a portable "tabula_mac.zip" archive (inside the build directory) for Mac OS X users.

Windows

You can build .exe files for the Windows target on any platform.

Download a 3.1.X (beta) copy of Launch4J.

Unzip it into the Tabula repo so that "launch4j" (with subdirectories "bin", etc.) is in the repository root.

Then:

rake windows

This will result in a portable "tabula_win.zip" archive (inside the build directory) for Mac OS X users.

If you have issues, you can try building manually. (These commands are for OS X/Linux and may need to be adjusted for Windows users.)

# (from the root directory of the repo)
rake war
cd launch4j
ant -f ../build.xml windows

A "tabula.exe" file will be generated in "build/windows". To run, the exe file needs "tabula.jar" (contained in "build") in the same directory. You can create a .zip archive by doing:

# (from the root directory of the repo)
cd build/windows
mkdir tabula
cp tabula.exe ./tabula/
cp ../tabula.jar ./tabula/
zip -r9 tabula_win.zip tabula
rm -fr tabula
