Reading is my hobby. I like to keep track of all the books I have read on an Excel spreadsheet so I can look back to see when I started reading, when I finished reading, the title of the book, and the author of each book.
この場合、次のような言い方ができますよ。
ーReading is my hobby. I like to keep track of all the books I have read on an Excel spreadsheet so I can look back to see when I started reading, when I finished reading, the title of the book, and the author of each book.
「読書は私の趣味で、読んだ本を全てエクセルで把握したいです。そうすればそれぞれの本の読書開始日、読了日、タイトル、筆者を後で見返すことができます」
when I finished reading で「読了日」と表現できます。
ご参考まで！
