RB to DOCM conversion is the process of transforming an RB ebook file—often a proprietary or less-common eBook/archive container—into a DOCM file, which is a Microsoft Word document that supports macros. This conversion extracts readable text, images and structure from the RB source and repackages them into a DOCM so the content is editable in Word while preserving embedded scripting where applicable.
