Export to Text Files
Mp3tag lets you export tag and file information to text-based formats via File → Export or ⌘E.
You can use any text along with the available placeholders and scripting functions to define the export format. Mp3tag applies this format to each selected file, generating a textual representation for each one. The resulting export file contains one line of output per file.
You can define a format string used to create the export filename at Preferences → Export.
Export to Clipboard
Mp3tag also lets you copy a textual representation of the selected files to the macOS clipboard via Edit → Copy or ⌘C.
The format string used to generate this textual representation can be configured under Preferences → Export.
