Final answer:
The best feature for Edward to use is Data Export, which allows extracting data from a database into a format that can be used in a spreadsheet and then saved for use by another application.
Step-by-step explanation:
Edward would accomplish his goal of gathering specific information from a database and then manipulating the data in a spreadsheet best by using the Data Export feature. Data Export allows users to generate files from the data contained in the database, which can then be imported into a spreadsheet for manipulation. This function is specifically designed to handle tasks like converting data into a format that is readable by other applications, such as CSV (Comma-Separated Values) or Excel formats, which are ideal for use with spreadsheet tools.
Once Edward has gathered and manipulated the data in the spreadsheet, he can save it again in a file format that is compatible with the other application he intends to use.
