Add and print comments in Numbers on Mac
You can add comments to text, objects, charts, table cells, and sheets. A small square appears next to text (which is also highlighted) to indicate a comment is attached. Comments attached to shapes are also indicated by a small square. Comments in table cells are indicated by a triangle in the corner of the cell. When you don’t want comments to be visible, you can hide them, and you can print a spreadsheet with or without comments.
When multiple people are working on a spreadsheet, each person’s comments appear in a unique color and include their author name. Anyone can reply to a comment, which is especially useful if you’re collaborating—you can add a comment, then with back-and-forth replies have a conversation in real time.
Note: Comments aren’t visible in printed spreadsheets unless you select that printing option.
Add, edit, or delete a comment
You can add and edit your own comments, and anyone can delete a comment.
Select text, or click an object or a table cell, then click
in the toolbar.Note: If you click the background of the sheet (so that nothing is selected), you can add a comment to the sheet that always stays open. You can resize the comment and reposition it on the sheet. Others can’t reply to this type of comment.
Type your comment, then click Done (or click outside the comment).
To view, edit, or delete your comment, do one of the following:
Open a comment: Click the comment marker (or move the pointer over the highlighted text).
Edit a comment: If you’re the comment’s author, open the comment, click in the text, then type.
If there are replies to your comment, you can’t edit the original comment by clicking its text. Instead, move the pointer over the timestamp to the right of your name at the top of the comment. When the down arrow appears, click it, choose Edit Comment, then make your changes.
Delete a comment: Click Delete at the bottom of the comment. If there are replies to the comment, this action deletes the entire conversation. You can delete an individual reply only if you’re the author of the reply or the spreadsheet owner.
If the comment is on the sheet background, move the pointer over the comment, then click Delete.
