Working with paragraphs

You can work with paragraphs in Node.js and apply many operations such as:

• Get all paragraphs that are included in a document or in a section.

Working with sections

You can create section/chapter, headers and footers in a Word document using node.js. Sections are the Word feature that controls page number formatting, headers and footers, orientation (portrait/landscape), margins and columns.
Section break usually is placed after the title page, copyright page, dedication page, table of contents, chapter 1, chapter 2, and so on. These section breaks will create a page break between each of those sections.
Using our Node.js library, you can perform the following operations on sections:

• Insert, delete or update a section break.
• Add section content.
• Copy sections between documents.
• Get a list of sections or a particular section from a Word document.
• Read or update page setup of a section.

const fs = require('fs');

var appSid = "####-####-####-####-####";
var appKey = "##################";

var wordsApi = new WordsApi(appSid, appKey);

var fileName = "sample.pdf";
var request = new ConvertDocumentRequest({
	format: "docx",
	document: fs.readFileSync(fileName),
});

wordsApi.convertDocument(request).then((result) => {
	fs.writeFile('sample.docx', result.body, (err) => {
		if (err) throw err;
		console.log('Successfully converted');
	});
}).catch(function(err) {
	console.log('Error:', err);
});
