We want to make changes to the author name of cell comments, we have to use Edit comments' option. We are having working hour’s calculator sheet in which we have inserted so many comments to remind the time calculations for our self and for other users too. Let’s take an example and understand how we can change the author name for all cell comments in a sheet. To change the author name we have to edit the comment box of the cell. After inserting the comment it appears with little red triangles to indicate comments in cells. To add comments in a cell, Excel provides the Insert Comment function. We can use comments in Excel to remind ourselves and inform someone else about what the cell contains. What are comments and how we can identify the comments in Excel. Before learning about how to change the author name in the comments box, we have to understand about the comments.
