You can read the email using the Get IMAP Mail Message activity and get the Body of Email in a Text then you can use the String manipulation/regex to find the required text and then store it in Excel/Word.
You may need to keep the following things in mind.
- You will need to create an App Password by going to your Google Account Settings (https://myaccount.google.com/apppasswords) and use that Password in the Get Mail Message Activity.
- To Get the Email Body the EmailMessage.Body property will not work instead you will need to use the EmailMessage.Headers("PlainText") Here EmailMessage is the Each Email Message from the list of Message. Here is the screenshot.

Above If condition is used to check if the Subject of Email which we want to read.
- Once you get the Email Body in a String Variable you can use either String Manipulation or Regex to extract the required data from the body of the email and write to the excel or word.
Hope this helps.
