Data Mart for Excel (D4E SQL) - 2026 Pricing, Features, Reviews & Alternatives

D4E functions as an add-in that manages enterprise-developed applications to deliver results directly within the MS Excel desktop environment. The system transforms secure applications into MS Excel widgets or data robots through Office APIs, enabling these applications to access databases via ODBC/SQL connections including Oracle, DB2, MSSQL, and Teradata. The integration allows organizations to build self-service data discovery tools while maintaining complete enterprise control over data access and manipulation processes.

The platform addresses significant governance and security concerns associated with user-developed applications by converting existing UDAs, VBA, PowerBI, SQL, and macros into a secured application store separate from user files. The centralized repository approach ensures that critical VBA code, SQL queries, and database credentials are converted, re-homed, and subject to proper change control protocols. The system employs encrypted database credentials that remain internal to the application, allowing security teams to maintain passwords without impacting end-users or automated operations.

D4E offers both standard and advanced versions to accommodate different organizational needs. The standard version enables developers to create and test SQL queries in edit mode while business users execute them in run mode through auto-configured menus without requiring SQL knowledge. The advanced version extends functionality with features such as scheduling macros, placeholder prompts, back-end servers, and MS Excel ribbon integration. The two-tier workflow design facilitates collaboration between IT departments and business users while maintaining enterprise-level security standards.
