html-docx-fixed based on html-docx-js
This is a very small library that is capable of converting HTML documents to DOCX format that is used by Microsoft Word 2007 and onward. It manages to perform the conversion in the browser by using a feature called 'altchunks'. In a nutshell, it allows embedding content in a different markup language. We are using MHT document to ship the embedded content to Word as it allows to handle images. After Word opens such file, it converts the external content to Word Processing ML (this is how the markup language of DOCX files is called) and replaces the reference.
Altchunks were not supported by Microsoft Word for Mac 2008 and are not supported by LibreOffice and Google Docs.
Compatibility
This library should work on any modern browser that supports Blobs
(either natively or via
Blob.js). It was tested on Google Chrome 36, Safari 7 and
Internet Explorer 10.
It also works on Node.js (tested on v0.10.12) using Buffer
instead of Blob
.
Images Support
This library supports only inlined base64 images (sourced via DATA URI). But it is easy to convert a
regular image (sourced from static folder) on the fly. If you need an example of such conversion you can checkout a demo page source (see function convertImagesToBase64
).
Usage and demo
Very minimal demo is available as test/sample.html
in the repository and
online. Please note that saving
files on Safari is a little bit convoluted and the only reliable method seems to be falling back
to a Flash-based approach (such as Downloadify).
Our demo does not include this workaround to keep things simple, so it will not work on Safari at
this point of time.
You can also find a sample for using it in Node.js environment here.
To generate DOCX, simply pass a HTML document (as string) to asBlob
method to receive Blob
(or Buffer
)
containing the output file.
import htmlDocx from 'html-docx-fixed/dist/html-docx';
import saveAs from 'file-saver';
var converted = htmlDocx.asBlob(content);
saveAs(converted, 'test.docx');
asBlob
can take additional options for controlling page setup for the document:
orientation
:landscape
orportrait
(default)margins
: map of margin sizes (expressed in twentieths of point, see WordprocessingML documentation for details):top
: number (default: 1440, i.e. 2.54 cm)right
: number (default: 1440)bottom
: number (default: 1440)left
: number (default: 1440)header
: number (default: 720)footer
: number (default: 720)gutter
: number (default: 0)
For example:
var converted = htmlDocx.asBlob(content, {orientation: 'landscape', margins: {top: 720}});
saveAs(converted, 'test.docx');
IMPORTANT: please pass a complete, valid HTML (including DOCTYPE, html
and body
tags).
This may be less convenient, but gives you possibility of including CSS rules in style
tags.
html-docx-js
is distributed as 'standalone' Browserify module (UMD). You can require
it as
html-docx
. If no module loader is available, it will register itself as window.htmlDocx
.
See test/sample.html
for details.
