Explanation
The "Create an Application From a File" wizard is a tool that allows developers to create an application based on an existing spreadsheet file or sample data set. Some of the statements that are true about loading data from this wizard are:
A sample data set from the sample list can be uploaded. You can use the Sample Data Sets option to select a predefined data set from a list of available samples, such as Employees, Products, Projects, etc.
CSV, XLSX, XML, TXT, or JSON files can be uploaded. You can use the Upload a File option to upload a spreadsheet file in one of these formats and create an application based on its data. You cannot upload seed data from a SQL script, paste and load XML and JSON data, or upload data from remote web services using this wizard. You can use other features in App Builder or SQL Workshop to perform these actions, such as SQL Scripts, RESTful Services, etc. VerifiedReferences: [Creating an Application From a File - Oracle Help Center], [Creating an Application Based on Sample Data Sets - Oracle Help Center]
