The TRANSCRIPTSTYLE file extension is associated with Apple iChat, an instant messaging application developed by Apple. A .transcriptstyle file stores a saved transcript style rather than the content of an individual conversation.
iChat used transcript styles to control how conversation transcripts were presented. The file belonged to iChat's style resources and was used together with the application when displaying or formatting chat transcripts.
Apple discontinued iChat and replaced it with Messages. Consequently, .transcriptstyle files are associated with legacy Mac OS X and macOS software and are not normally used by current macOS messaging applications.
Open a .transcriptstyle file with Apple iChat on a compatible older Mac OS X or macOS system. These files are intended to be selected or used by iChat as transcript style resources rather than opened as standalone documents.
Current versions of macOS do not include iChat, so they generally cannot use this file directly.
A .transcriptstyle file has no useful general-purpose conversion. It defines an iChat transcript style and is not a conversation transcript or a document format.
To preserve its appearance, keep the file with the related iChat style resources and use it with a compatible version of iChat.
