Delete All Comments in Excel

What this does

Modern Excel splits cell annotations in two. Review ▸ New Comment creates a threaded comment built for back-and-forth discussion, with a Reply box and the author's name. Review ▸ Notes ▸ New Note creates the old yellow sticky note for a standalone remark. Both attach to a cell, mark it with a small triangle in the corner (purple for comments, red for notes), and show on hover. Shift+F2 adds one to the active cell. Review ▸ Show Comments opens the side pane to read them all at once. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. For “delete all comments in excel”, the reliable version is a short checking loop, not just the first command that appears to work. Run it on a deliberately small range first, watch how the affected comments change, and only then apply the same setup to the full sheet. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. That is what makes a data step that keeps your analysis trustworthy useful in real work: repeatable, auditable, and not dependent on memory or luck.

A worked example

Right-click cell B2 and choose New Comment, type "Verify this figure with finance", then click away — a purple triangle appears in the corner of B2. Hover over B2 to read it, or click the triangle to reply. To leave a plain remark instead, pick Review ▸ Notes ▸ New Note and type the note. Comments and notes let you attach context — a caveat, a source, a question for a colleague — to a specific cell without cluttering the data itself. A practical tip: try it on a copy of the sheet or a handful of sample rows first and check the result before you apply it to the real data. That one habit catches almost every surprise while it is still cheap to reverse.

In Google Sheets

This is a command rather than a formula, so there is no syntax to carry over. Google Sheets arranges its commands in menus across the top instead of a ribbon, names some of them differently and does not have every Excel command — look for the equivalent in the Sheets menus or its help before assuming the steps match. Keep this page bookmarked for the next time the same question comes up. Better still, repeat the steps once in your own workbook — doing it yourself is what turns a copied answer into something you remember. The short version of “delete all comments in excel”: the answer is at the top of this page, and the sections above explain why each step matters, so a variation of the problem does not stump you. Try it once on a copy of a real file and the steps stick far better than re-reading them.

Common mistakes

• Confusing threaded comments with notes — converting a sheet between them loses the reply threads.
• Expecting comments to print by default — set Page Setup ▸ Sheet ▸ Comments to "At end of sheet" or "As displayed" first.
• Deleting a cell's contents and assuming the comment goes too — right-click ▸ Delete Comment to remove it.
• Looking for New Note under New Comment — in Microsoft 365 notes live under the separate Review ▸ Notes button.
