I do not know if there is in Mp3tag delivery version some standard predefined example export script for writing out a textfile in the form of Comma Separated Value convention.
Here are three examples to demonstrate how it goes:
Export CSV (comma) to Excel
$filename(Mp3tag.Export.comma.csv,ANSI)"Titel","Interpret","Album","Track","Tracktotal","Jahr","Dauer","Größe MB","Geändert","Pfad","Dateiname"
$loop(%_path%)"%title%","%artist%","%album%",$num(%track%,1),%_total%,"%year%",%_length%,%_file_size_mb%,%_file_mod_date%,"%_folderpath%","%_filename_ext%"
$loopend()
Export SSV (semicolon) to Excel
$filename(Mp3tag.Export.semicolon.csv,ANSI)"Titel";"Interpret";"Album";"Track";"Tracktotal";"Jahr";"Dauer";"Größe MB";"Geändert";"Pfad";"Dateiname"
$loop(%_path%)"%title%";"%artist%";"%album%";$num(%track%,1);%_total%;"%year%";%_length%;%_file_size_mb%;%_file_mod_date%;"%_folderpath%";"%_filename_ext%"
$loopend()
Export TSV (tab) to Excel
$filename(Mp3tag.Export.tab.csv,UTF-16)"Titel"$char(9)"Interpret"$char(9)"Album"$char(9)"Dauer"$char(9)"Bitrate"$char(9)"Genre"$char(9)"Dateiname"
$loop(%_folderpath%%_filename_ext%)"%title%"$char(9)"%artist%"$char(9)"%album%"$char(9)0:0:%_length_seconds%$char(9)%_bitrate%$char(9)"%genre%"$char(9)"%_filename_ext%"
$loopend()
