tabula-java is a library for extracting tables from PDF files — it is the table extraction engine that powers Tabula (repo). You can use
tabula-java as a command-line tool to programmatically extract tables from PDFs.
(This is the new version of the extraction engine; the previous code can be found at

Download a version of the tabula-java's jar, with all dependencies included, that works on Mac, Windows and Linux from our releases page.
tabula-java provides a command line application:
$ java -jar target/tabula-1.0.2-jar-with-dependencies.jar --help usage: tabula [-a <AREA>] [-b <DIRECTORY>] [-c <COLUMNS>] [-d] [-f <FORMAT>] [-g] [-h] [-i] [-l] [-n] [-o <OUTFILE>] [-p <PAGES>] [-r] [-s <PASSWORD>] [-t] [-u] [-v] Tabula helps you extract tables from PDFs -a,--area <AREA> Portion of the page to analyze. Example: --area 269.875,12.75,790.5,561. Accepts top,left,bottom,right i.e. y1,x1,y2,x2 where all values are in points relative to the top left corner. If all values are between 0-100 (inclusive) and preceded by '%', input will be taken as % of actual height or width of the page. Example: --area %0,0,100,50. To specify multiple areas, -a option should be repeated. Default is entire page -b,--batch <DIRECTORY> Convert all .pdfs in the provided directory. -c,--columns <COLUMNS> X coordinates of column boundaries where values are in points and relative to the left of the page. Example --columns 10.1,20.2,30.3 -d,--debug Print detected table areas instead of processing. -f,--format <FORMAT> Output format: (CSV,TSV,JSON). Default: CSV -g,--guess Guess the portion of the page to analyze per page. -h,--help Print this help text. -i,--silent Suppress all stderr output. -l,--lattice Force PDF to be extracted using lattice-mode extraction (if there are ruling lines separating each cell, as in a PDF of an Excel spreadsheet) -n,--no-spreadsheet [Deprecated in favor of -t/--stream] Force PDF not to be extracted using spreadsheet-style extraction (if there are no ruling lines separating each cell) -o,--outfile <OUTFILE> Write output to <file> instead of STDOUT. Default: - -p,--pages <PAGES> Comma separated list of ranges, or all. Examples: --pages 1-3,5-7, --pages 3 or --pages all. Default is --pages 1 -r,--spreadsheet [Deprecated in favor of -l/--lattice] Force PDF to be extracted using spreadsheet-style extraction (if there are ruling lines separating each cell, as in a PDF of an Excel spreadsheet) -s,--password <PASSWORD> Password to decrypt document. Default is empty -t,--stream Force PDF to be extracted using stream-mode extraction (if there are no ruling lines separating each cell) -u,--use-line-returns Use embedded line returns in cells. (Only in spreadsheet mode.) -v,--version Print version and exit.
It also includes a debugging tool, run
java -cp ./target/tabula-1.0.2-jar-with-dependencies.jar technology.tabula.debug.Debug -h for the available options.
You can also integrate
tabula-java with any JVM language. For Java examples, see the
JVM start-up time is a lot of the cost of the
tabula command, so if you're trying to extract many tables from PDFs, you have a few options for speeding it up:
- the drip utility
- the Ruby, Python, R, and Node.js bindings
- writing your own program in any JVM language (Java, JRuby, Scala) that imports tabula-java.
- waiting for us to implement an API/server-style system (it's on the roadmap)
