docx-mailmerge 0.5.0

Installation

Installation with pip:

$ pip install docx-mailmerge

Usage

Open the file.

from mailmerge import MailMerge
with MailMerge('input.docx') as document:
    ...

List all merge fields.

print document.get_merge_fields()

Merge fields, supplied as kwargs.

document.merge(field1='docx Mail Merge',
               field2='Can be used for merging docx documents')

Merge table rows. In your template, add a MergeField to the row you would like to designate as template. Supply the name of this MergeField as anchor parameter. The second parameter contains the rows with key-value pairs for the MergeField replacements.

document.merge_rows('col1',
                    [{'col1': 'Row 1, Column 1', 'col2': 'Row 1 Column 1'},
                     {'col1': 'Row 2, Column 1', 'col2': 'Row 2 Column 1'},
                     {'col1': 'Row 3, Column 1', 'col2': 'Row 3 Column 1'}])

Starting in version 0.2.0 you can also combine these two separate calls into a single call to merge.

document.merge(field1='docx Mail Merge',
               col1=[
                   {'col1': 'A'},
                   {'col1': 'B'},
               ])

Starting in version 0.2.0 there’s also the feature for template merging. This creates a copy of the template for each item in the list, does a merge, and separates them by page or section breaks (see function documentation).

When using this feature, make sure you don’t use comments, footnotes, bookmarks, etc. This is because these elements have an id attribute, which must be unique. This library does not handle this, resulting in invalid documents.

document.merge_templates([
    {'field1': "Foo", 'field2: "Copy #1"},
    {'field1': "Bar", 'field2: "Copy #2"},
], separator='page_break')

Write document to file. This should be a new file, as ZipFile cannot modify existing zip files.

document.write('output.docx')
