Apache POI HWPF and XWPF Apache POI provides Java APIs for working with Microsoft Documents.

We will cover use cases involving paragraphs, fonts, headers, footers, tables, images, write, read, parse and updating the document.

Before exploring use cases, lets cover basic concepts involving the Apache POI library.

HWPF (Horrible Word Processor Format) These APIs are for older Word 6 and Word 95 file formats,.doc documents.

XWPF (XML Word Processor Format) These APIs are for new Word 2007,.docx documents.

Component Description XWPFDocument It provides high level APIs to createedit.docx word files XWPFParagraph It is used for working with Paragraphs XWPFRun It defines a region of text with a common set of properties.

It is also used for editing font properties XWPFTable It is used to describe contents of table component present in word file XWPFTableRow It defines rows present within table component XWPFWordExtractor It is used to extract text from word file P.S This article will focus on the latest XWPF APIs, working with the.docx documents.

Apache POI dependencies We only need the poi-ooxml to work with Microsoft word.

It contains methods for changing font properties such as color, font size, italic, bold, capitalized, embossed, and many more.

We are creating four paragraphs and setting different font properties, line breaks, and page breaks for each of them.

Document header and footer This example creates the documents header and footer for all pages.

Add an image This example adds an image to the document.

We will use the XWPFTable component to create and initialize a table element.

This example inserts a table containing 3 rows and 3 columns.

This example will cover how we can use Apache POI for extracting and reading out text from documents.

We can extract the entire text from document by using XWPFWordExtractor.

Once we get the list, we can iterate over individual paragraph elements and get the text.

Create table. We need to fetch the list of all elements in the file and then iterate over it to check for the TABLE component.

Once we find the TABLE component, we can iterate over it to fetch table rows and finally iterate over the rows to extract the tables values.

And we will replace the string name with a predefined input and create a new file output.docx with the updated contents.
