What Open as App is
Open as App turns spreadsheets and other data into no-code mobile and web apps. Users can start with Excel files, Google Sheets, cloud file URLs, or connected external storage, while recognized spreadsheet logic can be used inside apps and written back to a shared source. Apps can be assembled with components, templates, company branding, logos, and images without coding. Creators set access rights, and apps remain private until shared. Published apps work on iOS, Android, and the web through the container app and web client. Integrations listed include Excel/CSV, Google Sheets, REST API, and MySQL, MS SQL, and Postgres drivers. Zapier and Power Automate can connect web services. Open as App states it has ISO 27001 certification. It has no built-in database, and Google Sheets-only functions are unsupported after conversion to Excel.
