DocxEditor

Replace text / images in a Microsoft Word .docx file, no dependencies

DocxEditor, can be used to Replace text / images in a Microsoft Word .docx file. Example usage, is a template of a report with some default text and images which are replaced to generate a report in a certain style.

It has no dependencies, no Microsoft Word, no toolboxes, it simply unzips, the .docx uses Matlab's xml functions to manipulate the files, and then zips it back to a .docx file.

Example code:

editor = DocxEditor('template.docx';);

editor.replaceBatch({ ...

"%footer_text%", 'footer noise template';

"%header_text%", 'header noise template';

"%title%", 'Noise Template';

"%cell1%", 'Table cell left';

"%cell2%", 'Table cell right';

"%first%", 'first bullet point';

"%second%", 'second bullet point';

"%second_page%", 'second page' ...

});

im = uint8(rand(256,256,3)*255);

im_std = std(single(im(:)));

editor.replaceText("%mainstd%", sprintf('%0.5f', im_std));

editor.replaceText("%figure1%", 'color noise');

filenames_images = editor.listImages();

editor.replaceImage(filenames_images{1}, im);

im2 = uint8(rand(256,256,1)*255);

im_std2 = std(single(im2(:)));

editor.replaceText("%mainstd2%", sprintf('%0.5f', im_std2));

editor.replaceText("%figure2%", 'grey noise');

imwrite(im2, 'temp.png');

editor.replaceImage(filenames_images{2}, 'temp.png');

editor.save('test.docx');
