Builder Complex spreadsheets are inherently flaky. Accidental edits, overwritten data, and manual updates quickly disrupt important business processes. But you can now upload an existing spreadsheet to Aha! Builder and use AI to transform it into an intuitive application. Create a business application from an existing spreadsheet in Aha! Builder — without having to recreate the data and logic from scratch. ## Go beyond the spreadsheet Our [AI app builder](https://www.aha.io/builder/overview) is designed for the enterprise — use it to create prototypes and trusted business applications. You could already begin building by describing an idea in plain language. Now, you can also start by uploading a spreadsheet and let Elle (the AI assistant) transform it into an intuitive application. When you create a new application in Aha! Builder, select the spreadsheet option and upload an XLSX or XLSM file. Elle reads the worksheet structure, data, formulas, and macros, then recreates the underlying logic in your application. Keep chatting with Elle to build out the application. - **Match your design** to create a more intuitive user experience. - **Enhance the workflow** with email notifications, persistent data storage, and AI features. - **Integrate** with other tools like Slack, Salesforce, Jira, and more. - **Control access** with built-in authentication and user permissions. Moving the workflow into an application frees it from the limits of the original spreadsheet. Create an interface designed for the task, and add powerful capabilities to give your teammates a better experience. Consider which spreadsheet-based processes on your team are good candidates to convert. (Pricing calculators, inventory trackers, budget models, project trackers, approval processes, or resource plans might make good options.) Pick one your team depends on and build the application you would rather use.
