Word Add-in Development Services We Offer
SCAND provides custom Microsoft Word add-ins designed to automate workflows, improve document quality, and seamlessly integrate with business systems. Below are some of the solutions we deliver for different use cases.
Template and Formatting Automation
We develop Word add-ins that automate document formatting and ensure consistency with corporate standards. Our solutions help businesses apply branded templates, manage styles, automate numbering, and maintain uniform document layouts, reducing manual work and formatting errors.
Legal Drafting and Clause Libraries
SCAND builds Word add-ins that simplify legal document preparation and review. Our solutions enable legal teams to search and insert approved clauses, manage clause libraries, create cross-references, and redact sensitive information, ensuring greater accuracy, consistency, and compliance throughout the drafting process.
We build Word add-ins that generate proposals, contracts, and reports from CRM and ERP data. Users choose a template, the add-in fills in client details, prices, and terms, and the document is ready for review in minutes.
CRM, ERP and SharePoint Integrations
We develop Word add-ins that connect document workflows with CRM, ERP, and other enterprise systems. Using our SharePoint development and Microsoft Graph API integration expertise, we enable automated data retrieval, document generation, template population, and secure access to business information directly within Word.
Review and Collaboration Add-ins
SCAND creates Word add-ins that streamline document reviews, approvals, and team collaboration. Our solutions support contextual comments, structured approval workflows, and change tracking through supported Word APIs. They help teams coordinate feedback, manage document revisions, and accelerate approval cycles while maintaining transparency throughout the review process.
AI Writing Assistants
We build AI-powered Word add-ins that assist with content creation, editing, and document analysis. Our solutions provide intelligent suggestions for grammar, tone, clarity, and readability, as well as text generation, rewriting, and document summarization. By combining AI capabilities with document automation, we help businesses produce high-quality content faster and reduce editing time.
Cross-Platform Word Add-ins
SCAND develops Word add-ins designed to work across Windows, Mac, Word on the web, and iPad. Using modern Office.js technologies, we create consistent, intuitive user experiences while accounting for platform-specific capabilities, helping businesses access essential document tools across devices. The same approach underpins our Microsoft Office add-in development for Excel, Outlook, and PowerPoint.
VSTO and COM Migration to Office.js
We help businesses modernize legacy Word add-ins by migrating VSTO and COM solutions to Office.js. Our VSTO add-in development expertise enables us to assess existing functionality, redesign integrations, and rebuild supported features for modern Word environments, improving maintainability, cross-platform compatibility, and long-term scalability.
Enterprise Deployment and Security
SCAND develops enterprise-ready Word add-ins with security, centralized management, and scalability in mind. Our solutions support single sign-on (SSO) through Microsoft Entra ID, secure authentication, and centralized deployment across Microsoft 365 environments. We also assist with publishing and distributing add-ins through Microsoft Marketplace, helping organizations simplify adoption and administration.
What We Build with the Word JavaScript API
SCAND develops custom Word add-ins using Office.js to automate document workflows, extend functionality, and integrate enterprise systems. For advanced document structures, we leverage OOXML, while Windows-specific features and deeper desktop integration may require VSTO.
- Content Controls and Data Binding: We create structured document fields and connect them to CRM, ERP, and other data sources to automatically populate templates and update document content.
- OOXML Insertion: We use Office Open XML (OOXML) to generate and insert complex tables, tables of contents, and richly formatted content while preserving document structure.
- Headers, Footers, Sections, and Styles: Document layouts, corporate formatting, and section-specific elements are automated to ensure consistency across professional documents.
- Custom XML Parts: Our solutions use structured document metadata to power data-driven templates, document identification, and seamless integration with external systems.
- Track Changes and Comments: We develop review and approval tools that track revisions, handle comments, and streamline collaboration through Word APIs.
