Underlining is a simple way to draw attention to important content in a Word DOC file. It can help when marking terms in reports or pointing out sections that need another look. Unlike changing the document text itself, an underline annotation can be utilized as a separate markup layer during document review. If you are working with Word documents and need a practical way to mark specific words or passages, the GroupDocs.Annotation Cloud Node.js SDK is all you need. It helps you add underline annotations to DOC files in Node.js using a REST API. This solution is an ideal choice for document workflows that require review or automatic processing of multiple files. Let’s review the step-by-step process.

Steps to Add Underline Annotations to DOC Files in Node.js

1. Import and set up GroupDocs.Annotation Cloud SDK for Node.js
2. Obtain your API credentials and configure them with AnnotateApi
3. Add the source DOC file with FileInfo
4. Create an underline annotation and set properties with AnnotationInfo
5. Define annotation options like the output file path with AnnotateOptions
6. Create a request to annotate a DOC file and execute it with the annotate() method

The initial step for adding an underline annotation to a DOC file is sending the document and annotation details through the cloud API. You can identify the text location, define the annotation position, and apply the markup to the selected content. Using a DOC annotation API can reduce the need for repeated manual document editing. Underline markups can be added to Word documents as part of a review process, making it easier to identify important text across multiple files. Processing happens via the Node.js REST API, so you do not need to install a separate document-editing application on the system handling the files.

The GroupDocs.Annotation Cloud Node.js SDK allows you to add underline annotations to DOC files and mark text during document review. While preparing reports or reviewing shared Word documents, the underline annotations make selected content easier to spot and revisit. You can build Node.js applications for document review portals, content management tools, collaboration workflows, and other services where users need to mark up DOC files. The Node.js REST API enables you to highlight important clauses in a word-processing document. The resulting document becomes available for further processing as part of your existing workflow. Your applications run on Windows, Linux, and macOS without any significant modifications.
