¿Cómo puedo convertir un archivo .TXT en un archivo .CSV sin perder ninguno de los contenidos de ese documento?

He estado intentando durante unos 4 días completar la aparentemente simple actividad de convertir un volcado de texto del llavero OS X en un archivo .csv con el formato correcto sin progreso, y mucho menos éxito. Publiqué una pregunta diferente sobre mi situación ayer, que se ha ido sin comentarios o sugerencia.

Simplemente estoy intentando convertir un archivo .txt en un archivo .csv formateado, sin perder ninguno de los contenidos del documento original en el proceso.

Lo que ya he probado:

(1) RWest's Gist y Ben-Oni y christophervalles variaciones de los mismos. El ingrediente principal de este script es un archivo keychain.rb y creo que esto funcionaría si solo supiera cómo agregar campos de entrada para que coincidan con todos los campos del documento original. Sin embargo, no conozco la fórmula y no he podido encontrar una plantilla. Como tal, la ejecución de este script da como resultado cientos de entradas faltantes porque las entradas carecen del campo de salida correspondiente.

(4) Swiss File Knife parecía prometedor ya que tiene un comando incorporado para convertir el texto separado por tabulaciones en coma texto separado. Sin embargo, ejecutar el comando dio lugar a docenas y docenas y docenas de errores de "formato incorrecto". Supongo que mi archivo .txt debería ser un archivo .tsv para que el comando realmente funcione y no he podido encontrar ninguna forma de convertir un .txt en un .tsv.

Entonces, aquí es donde estoy ahora, días más tarde, en el mismo lugar donde empecé. ¿Puede alguien, por favor, decirme cómo modificar los campos de entrada del primer guión de RWest para que todo el contenido pase al .csv o sugerir un método alternativo, guión, aplicación, baile de lluvia, etc. que ¿Me permitirá simplemente que todos los datos del archivo de texto aparezcan en un archivo csv, con las columnas y filas adecuadas que separan cada entrada?

EDIT: esto es lo que obtienes cuando solo cambias la extensión del archivo:
