Excel-Based Annotating the Active Cell

This template, which allows for quickly leaving notes on the selected cell, strengthens internal document communication. Also, it allows for keeping reminder or informative messages organized during data entries. Because, presenting comment boxes in a standard structure preserves the aesthetics and clarity of the document. Thus, a guiding structure is created in files examined by others. Therefore, this file is a strategic assistant in projects worked on collaboratively.
