The platform is designed to let Excel continue to serve as the user interface while FinanceOS operates as the underlying data layer, connecting to more than 600 native system connectors without requiring companies to replace existing software. Datarails uses AI and machine learning within FinanceOS to support real-time financial consolidation and data visualization, and the company holds patents for its Excel-to-database transformation technology.
