SpreadsheetWeb is a no-code platform developed for business users working with Microsoft Excel. It helps businesses translate their collective Excel expertise into robust web applications with limited reliance on IT resources. The SpreadsheetWeb platform empowers ordinary Excel users to create secure, responsive, database-driven applications directly from their Excel spreadsheets. By transforming the data collection mechanism from individual file-based spreadsheets into structured databases while maintaining the formula structure, the system provides a higher level of governance for critical information. Combined with built-in workflow and reporting capabilities, SpreadsheetWeb offers an end-to-end platform for business users seeking to create and manage their own web applications. The biggest distinction of SpreadsheetWeb from other no-code platforms is its ability to maintain and execute Excel formulas in the application. This saves users from learning a new language to program their business logic. They can use the entire formula structures in their Excel spreadsheets and execute them from the web application without any modifications. As the calculation model evolves, users can continue relying on their familiarity with the Excel platform to perform modifications. With support for over 450 Excel formulas, SpreadsheetWeb can execute even the most complex Excel-based workbooks.
