When referring to something as a whole, it's often said to be "in its entirety." However, there are other expressions that convey the same meaning. One alternative is "in full," which suggests that nothing has been left out or omitted. Another option is "the whole enchilada," which is a more playful way to describe the entirety of something. "In total" also works, as it implies a complete view of the subject. "The sum total" is another phrase that conveys the same idea. Finally, "from start to finish" is a more descriptive option that implies the entirety of a process.
