OOXML to CALS converter


The convert_ooxml2cals() converter is a function designed to convert tables from an Office Open XML (OOXML) document (which respects the schema defined in Office Open XML File Formats) in the CALS table format.

The conversion is done in the source XML document by replacing the tables of the OOXML format with those transformed in the CALS format. In other words, the general structure of the source XML document is retained except for tables.

The Ooxml2CalsConverter converter is composed of:

  • a OoxmlParser parser that allows you to parse tables in OOXML format,

    The tutorial OOXML tables (Word) parser describes the usage of this parser and gives some examples.

  • a CalsBuilder builder that allows you to build tables in the CALS format.

    The tutorial CALS tables builder describes the usage of this builder and gives some examples.

Conversion options

The tables parsing and building can be parameterized using the options described below:

Common parsing options:

encoding (default: “utf-8”):

XML encoding of the destination file.

OOXML parser options:

styles_path (default: None):

Path to the stylesheet to use to resole table styles. In an uncompressed .docx tree structure, the stylesheet path is word/styles.xml.

CALS builder options:

cals_ns (default: None):

Namespace to use for CALS-like elements and attributes to generate. Set None (or “”) if you don’t want to use namespace.

cals_prefix (default: None):

Namespace prefix to use for CALS-like elements and attributes to generate.

width_unit (default: “mm”):

Unit to use for column widths. Possible values are: ‘cm’, ‘dm’, ‘ft’, ‘in’, ‘m’, ‘mm’, ‘pc’, ‘pt’, ‘px’.

table_in_tgroup (default: False):

Where should we put the table properties:

  • False to insert the attributes @colsep, @rowsep, and @tabstyle in the <table> element,

  • True to insert the attributes @colsep, @rowsep, and @tgroupstyle in the <tgroup> element.

tgroup_sorting (default: ["header", "footer", "body"]):

List used to sort (and group) the rows in a tgroup. The sorting is done according to the row natures which is by default: ["header", "footer", "body"] (this order match the CALS DTD defaults, where the footer is between the header and the body. To move the footer to the end, you can use ["header", "body", "footer"].
