In Excel: select the row numbers, right-click and choose Hide; to bring them back, select the rows around the gap (or Ctrl+A for the whole sheet) and choose Unhide, or use Home ▸ Format ▸ Hide & Unhide.

Click a row number and drag (or Ctrl-click) to select the whole rows you want to hide.
Right-click the selection and choose Hide, or use Home ▸ Format ▸ Hide & Unhide ▸ Hide Rows.
To unhide a few, select the rows immediately above and below the gap, right-click and choose Unhide.
To unhide every row at once, press Ctrl+A, then Home ▸ Format ▸ Hide & Unhide ▸ Unhide Rows.
What this does
Hiding a row collapses it out of view without deleting anything — the data, formulas and any totals that reference it all keep working, the row is simply not shown. You select whole rows by their numbers, right-click and pick Hide, and a doubled border marks where rows are missing. Unhiding reverses it: select the rows on either side of the gap and choose Unhide. To reveal every hidden row at once, select the entire sheet with Ctrl+A first. Before you run it on a workbook other people depend on, try it on a copy or a few rows first. Undo only reaches back through the current session, so a quick trial run is the cheapest way to see exactly what will change before the file is saved and shared. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “unhide all hidden rows in excel”. Start on a copy or a tiny sample, keep the affected rows visible, and compare the result with the outcome you expected before you touch the real workbook. 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. The point is a layout choice that keeps the sheet readable and sortable, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
A report has detail in rows 5–8 you want out of the way. Click row header 5, drag to row 8 to select all four, right-click and choose Hide — rows 5 to 8 vanish and the numbering jumps from 4 straight to 9. Later, to bring them all back, press Ctrl+A to select the whole sheet, then Home ▸ Format ▸ Hide & Unhide ▸ Unhide Rows, and rows 5–8 reappear exactly as they were. Hide rows to tuck away detail, helper calculations or seasonal entries without losing them — a cleaner print-out, a tidier review, a report that shows only the summary. Because nothing is deleted, you can unhide and get every row back exactly as it was whenever you need it. When the result is not what you expected, undo straight away rather than repairing it by hand — undo restores the sheet exactly, while manual fixes tend to leave small inconsistencies behind that surface later.
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. Nothing on this page is behind a login or a download: the exact answer is at the top, and the detail below it is there for when you need it. That is the whole promise here — the answer first, and just enough context to make it stick. Here is the takeaway for “unhide all hidden rows in excel”: follow the steps at the top, check the result on the sheet itself, and keep undo in mind while you experiment. Done once deliberately, it becomes something you do from memory in Excel rather than something you search for again.
Common mistakes
- Selecting cells instead of whole row headers, so Hide is greyed out or hides the wrong thing.
- Forgetting hidden rows still count in
SUMand other ranges — hiding does not exclude them from formulas. - Trying to unhide row 1 by selecting around it (there is no row above) — instead select from row 1 down, or use the Name Box and Unhide Rows.
- Confusing hiding with filtering; a filter hides rows by condition and is cleared differently from a manual Hide.
Frequently asked questions
How do I unhide all rows at once?
Select the entire sheet with Ctrl+A (or click the corner box above row 1), then Home ▸ Format ▸ Hide & Unhide ▸ Unhide Rows reveals every hidden row in one step.
Do hidden rows still affect my totals?
Yes — SUM and most functions still include hidden rows. Use SUBTOTAL or AGGREGATE if you need a total that ignores hidden rows.
How do I unhide the very first row?
There is no row above row 1 to select, so type A1 in the Name Box to land there, then Home ▸ Format ▸ Hide & Unhide ▸ Unhide Rows.
