Html-to-docx-update NPM

html-to-docx-update

html-to-docx is a js library for converting HTML documents to DOCX format supported by Microsoft Word 2007+, LibreOffice Writer, Google Docs, WPS Writer etc.

It was inspired by html-docx-js project but mitigates the problem of documents generated being non-compatiable with word processors like Google Docs and libreOffice Writer that doesn't support altchunks feature.

html-to-docx earlier used to use libtidy to clean up the html before parsing, but had to remove it since it was causing so many dependency issues due to node-gyp.

important

html-to-docx-update contains

footer page number like page 1 of 3
paragraph spacing removed

Disclaimer

Even though there is an instance of html-to-docx running in production, please ensure that it covers all the cases that you might be encountering usually, since this is not a complete solution.

Currently it doesn't work with browser directly, but it was tested against React.

Notes

Currently page break can be implemented by having div with classname "page-break" or style "page-break-after" despite the values of the "page-break-after", and contents inside the div element will be ignored. <div class="page-break" style="page-break-after: always;"></div>

CSS list-style-type for <ol> element are now supported. Just do something like this in the HTML:

  <ol style="list-style-type:lower-alpha;">
    <li>List item</li>
    ...
  </ol>

List of supported list-style-types:

upper-alpha, will result in A. List item
lower-alpha, will result in a. List item
upper-roman, will result in I. List item
lower-roman, will result in i. List item
lower-alpha-bracket-end, will result in a) List item
decimal-bracket-end, will result in 1) List item
decimal-bracket, will result in (1) List item
decimal, (the default) will result in 1. List item

Also you could add attribute data-start="n" to start the numbering from the n-th.

<ol data-start="2"> will start the numbering from ( B. b. II. ii. 2. )

Font family doesnt work consistently for all word processor softwares

Word Desktop work as intended
LibreOffice ignores the fontTable.xml file, and finds a font by itself
Word Online ignores the fontTable.xml file, and finds closest font in their font library
