tabula

High level interfaces

tabula.io

This module is a wrapper of tabula, which enables table extraction from a PDF.

This module extracts tables from a PDF into a pandas DataFrame via jpype.

Instead of importing this module, you can import public interfaces such as read_pdf(), read_pdf_with_template(), convert_into(), convert_into_by_batch() from tabula module directory.

Note

If you want to use your own tabula-java JAR file, set TABULA_JAR to environment variable for JAR path.

Example

>>> import tabula
>>> dfs = tabula.read_pdf("/path/to/sample.pdf", pages="all")
tabula.io.convert_into(input_path: IO | str | PathLike, output_path: str, output_format: str = 'csv', java_options: List[str] | None = None, pages: str | int | Iterable[int] | None = None, guess: bool = True, area: Iterable[float] | Iterable[Iterable[float]] | None = None, relative_area: bool = False, lattice: bool = False, stream: bool = False, password: str | None = None, silent: bool | None = None, columns: Sequence[float] | None = None, relative_columns: bool = False, format: str | None = None, batch: str | None = None, force_subprocess: bool = False, options: str = '') → None[source]

Convert tables from PDF into a file. Output file will be saved into output_path.

Parameters:

  • input_path (file like obj) – File like object of target PDF file.

  • output_path (str) – File path of output file.

  • output_format (str, optional) – Output format of this function (csv, json or tsv). Default: csv

  • java_options (list, optional) –

    Set java options. This option will be ignored once JVM is launched.

    Example

    "-Xmx256m".

  • pages (str, int, iterable of int, optional) –

    An optional values specifying pages to extract from. It allows str,`int`, iterable of :int. Default: 1

    Examples

    '1-2,3', 'all', [1,2]

  • guess (bool, optional) –

    Guess the portion of the page to analyze per page. Default True If you use “area” option, this option becomes False.

    Note

    As of tabula-java 1.0.3, guess option becomes independent from lattice and stream option, you can use guess and lattice/stream option at the same time.

  • area (iterable of float, iterable of iterable of float, optional) –

    Portion of the page to analyze(top,left,bottom,right). Default is entire page.

    Note

    If you want to use multiple area options and extract in one table, it should be better to set multiple_tables=False for read_pdf()

    Examples

    [269.875,12.75,790.5,561], [[12.1,20.5,30.1,50.2], [1.0,3.2,10.5,40.2]]

  • relative_area (bool, optional) – If all area values are between 0-100 (inclusive) and preceded by '%', input will be taken as % of actual height or width of the page. Default False.

  • lattice (bool, optional) – 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)

  • stream (bool, optional) – Force PDF to be extracted using stream-mode extraction (if there are no ruling lines separating each cell, as in a PDF of an Excel spreadsheet)

  • password (str, optional) – Password to decrypt document. Default: empty

  • silent (bool, optional) – Suppress all stderr output.

  • columns (Sequence, optional) –

    X coordinates of column boundaries. Must be sorted and of a datatype that preserves order, e.g. tuple or list

    Example

    [10.1, 20.2, 30.3]

  • format (str, optional) – Format for output file or extracted object. ("CSV", "TSV", "JSON")

  • batch (str, optional) – Convert all PDF files in the provided directory. This argument should be directory path.

  • force_subprocess (bool) – Force to use tabula-java subprocess mode. If you have some issue with jpype, try this option with same environment. Default False.

  • options (str, optional) – Raw option string for tabula-java.

Raises:

  • FileNotFoundError – If downloaded remote file doesn’t exist.

  • ValueError – If output_format is unknown format, or if downloaded remote file size is 0.

  • tabula.errors.JavaNotFoundError – If java is not installed or found.

  • subprocess.CalledProcessError – If tabula-java execution failed.

Read tables in PDF.

Parameters:

  • input_path (str, path object or file-like object) – File like object of target PDF file. It can be URL, which is downloaded by tabula-py automatically.

  • output_format (str, optional) – Output format for returned object (dataframe or json) Giving this option enforces to ignore multiple_tables option.

    Note

    With multiple_tables=True (default), pandas_options is passed to pandas.DataFrame, otherwise it is passed to pandas.read_csv. Those two functions are different for accept options like dtype.

  • multiple_tables (bool) –

    It enables to handle multiple tables within a page. Default: True

    Note

    If multiple_tables option is enabled, tabula-py uses not pd.read_csv(), but pd.DataFrame(). Make sure to pass appropriate pandas_options.

Examples

Here is a simple example. Note that read_pdf() only extract page 1 by default.

Notes:

As of tabula-py 2.0.0, read_pdf() sets multiple_tables=True by default. If you want to get consistent output with previous version, set multiple_tables=False.

Read tables in PDF with a Tabula App template.

Parameters:

  • input_path (str, path object or file-like object) – File like object of target PDF file. It can be URL, which is downloaded by tabula-py automatically.

  • template_path (str, path object or file-like object) – File like object for Tabula app template. It can be URL, which is downloaded by tabula-py automatically.

  • pandas_options (dict, optional) – Set pandas options like {‘header’: None}.

  • encoding (str, optional) – Encoding type for pandas. Default is ‘utf-8’

  • java_options (list, optional) – Set java options like ["-Xmx256m"]. This option will be ignored once JVM is launched.

  • user_agent (str, optional) – Set a custom user-agent when download a pdf from a url. Otherwise it uses the default urllib.request user-agent.

  • use_raw_url (bool) – It enforces to use input_path string for url without quoting/dequoting. Default: False

  • pages (str, int, iterable of int, optional) –

    An optional values specifying pages to extract from. It allows str,`int`, iterable of :int. Default: 1

    Examples

    '1-2,3', 'all', [1,2]

  • guess (bool, optional) –

    Guess the portion of the page to analyze per page. Default True If you use “area” option, this option becomes False.

    Note

    As of tabula-java 1.0.3, guess option becomes independent from lattice and stream option, you can use guess and lattice/stream option at the same time.

  • area (iterable of float, iterable of iterable of float, optional) –

    Portion of the page to analyze(top,left,bottom,right). Default is entire page.

    Note

    If you want to use multiple area options and extract in one table, it should be better to set multiple_tables=False for read_pdf()

    Examples

    [269.875,12.75,790.5,561], [[12.1,20.5,30.1,50.2], [1.0,3.2,10.5,40.2]]

  • relative_area (bool, optional) – If all area values are between 0-100 (inclusive) and preceded by '%', input will be taken as % of actual height or width of the page. Default False.

  • lattice (bool, optional) – 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)

  • stream (bool, optional) – Force PDF to be extracted using stream-mode extraction (if there are no ruling lines separating each cell, as in a PDF of an Excel spreadsheet)

  • password (str, optional) – Password to decrypt document. Default: empty

  • silent (bool, optional) – Suppress all stderr output.

  • columns (Sequence, optional) –

    X coordinates of column boundaries. Must be sorted and of a datatype that preserves order, e.g. tuple or list

    Example

    [10.1, 20.2, 30.3]

  • relative_columns (bool, optional) – If all values are between 0-100 (inclusive) and preceded by ‘%’, input will be taken as % of actual width of the page. Default False.

  • format (str, optional) – Format for output file or extracted object. ("CSV", "TSV", "JSON")

  • batch (str, optional) – Convert all PDF files in the provided directory. This argument should be directory path.

  • output_path (str, optional) – Output file path. File format of it is depends on format. Same as --outfile option of tabula-java.

  • force_subprocess (bool) – Force to use tabula-java subprocess mode. If you have some issue with jpype, try this option with same environment. Default False.

  • options (str, optional) – Raw option string for tabula-java.

Returns:

list of DataFrame.

Raises:

  • FileNotFoundError – If downloaded remote file doesn’t exist.

  • ValueError – If output_format is unknown format, or if downloaded remote file size is 0.

  • tabula.errors.CSVParseError – If pandas CSV parsing failed.

  • tabula.errors.JavaNotFoundError – If java is not installed or found.

  • subprocess.CalledProcessError – If tabula-java execution failed.

Examples

You can use template file extracted by tabula app.

Utility module providing some convenient functions.

class tabula.util.TabulaOption(pages: str | int | Iterable[int] | None = None, guess: bool = True, area: Iterable[float] | Iterable[Iterable[float]] | None = None, relative_area: bool = False, lattice: bool = False, stream: bool = False, password: str | None = None, silent: bool | None = None, columns: Sequence[float] | None = None, relative_columns: bool = False, format: str | None = None, batch: str | None = None, output_path: str | None = None, options: str | None = '', multiple_tables: bool = True)[source]

Bases: object

Build options for tabula-java

Parameters:

  • pages (str, int, iterable of int, optional) –

    An optional values specifying pages to extract from. It allows str,`int`, iterable of :int. Default: 1

    Examples

    '1-2,3', 'all', [1,2]

  • guess (bool, optional) –

    Guess the portion of the page to analyze per page. Default True If you use “area” option, this option becomes False.

    Note

    As of tabula-java 1.0.3, guess option becomes independent from lattice and stream option, you can use guess and lattice/stream option at the same time.

  • area (iterable of float, iterable of iterable of float, optional) –

    Portion of the page to analyze(top,left,bottom,right). Default is entire page.

    Note

    If you want to use multiple area options and extract in one table, it should be better to set multiple_tables=False for read_pdf()

    Examples

    [269.875,12.75,790.5,561], [[12.1,20.5,30.1,50.2], [1.0,3.2,10.5,40.2]]

  • relative_area (bool, optional) – If all area values are between 0-100 (inclusive) and preceded by '%', input will be taken as % of actual height or width of the page. Default False.

  • lattice (bool, optional) – 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)

  • stream (bool, optional) – Force PDF to be extracted using stream-mode extraction (if there are no ruling lines separating each cell, as in a PDF of an Excel spreadsheet)

  • password (str, optional) – Password to decrypt document. Default: empty

  • silent (bool, optional) – Suppress all stderr output.

  • columns (Sequence, optional) –

    X coordinates of column boundaries. Must be sorted and of a datatype that preserves order, e.g. tuple or list

    Example

    [10.1, 20.2, 30.3]

  • relative_columns (bool, optional) – If all values are between 0-100 (inclusive) and preceded by ‘%’, input will be taken as % of actual width of the page. Default False.

  • format (str, optional) – Format for output file or extracted object. ("CSV", "TSV", "JSON")

  • batch (str, optional) – Convert all PDF files in the provided directory. This argument should be directory path.

  • output_path (str, optional) – Output file path. File format of it is depends on format. Same as --outfile option of tabula-java.

  • options (str, optional) – Raw option string for tabula-java.

  • multiple_tables (bool, optional) – Extract multiple tables into a dataframe. Default: True

area: Iterable[float] | Iterable[Iterable[float]] | None = None
batch: str | None = None
