When a file is saved in Excel, the program automatically appends the appropriate file extension based on the format chosen by the user, such as .xlsx for standard workbooks or .xls for older formats. This extension is crucial for the operating system and other applications to recognize the file type and determine how to open it. Users can change the file format during the save process, but Excel will still add the corresponding extension to ensure proper identification. Failure to include the correct extension can lead to difficulties in opening the file later.
