In Excel: right-click any sheet tab and choose Unhide, then pick the sheet from the list — in Microsoft 365 you can Ctrl-click several at once.
Right-click any worksheet tab and choose Unhide.
Pick the sheet you want; in Microsoft 365 Ctrl-click to select several, then press OK.
If Unhide is greyed out, check Review ▸ Protect Workbook — a protected structure blocks it.
If the sheet is not in the list, press Alt+F11 to open the VBA editor and find it in the Project pane.
With the sheet selected, set Visible to -1 - xlSheetVisible in the Properties window (press F4 if it is not showing).
To unhide everything in one go, open the Immediate window with Ctrl+G and run: For Each s In Sheets: s.Visible = -1: Next
What this does
Excel has two levels of hiding and only one of them is in that dialog. A normally hidden sheet is what right-click ▸ Hide produces and right-click ▸ Unhide reverses. A *very* hidden sheet has its Visible property set to xlSheetVeryHidden in the VBA editor, and it does not appear in the Unhide list at all — the only ways back are the VBA Properties window (Alt+F11, select the sheet, set Visible to -1 xlSheetVisible) or a one-line macro. If Unhide is greyed out entirely, either no sheet is hidden or the workbook structure is protected, which is Review ▸ Protect Workbook. 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. Treat “excel hidden sheets” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected sheet shows up while it is still harmless. 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 turns a layout choice that keeps the sheet readable and sortable into a method you can reuse, explain, and defend when the workbook leaves your screen.
A worked example
Right-click any tab ▸ Unhide shows Sheet3 and Config; select one and press OK. If a sheet you know exists is missing from that list, press Alt+F11, click the sheet in the Project pane, and in the Properties window set Visible from 2 - xlSheetVeryHidden to -1 - xlSheetVisible. To reveal everything at once, run this in the VBA Immediate window: For Each s In Sheets: s.Visible = -1: Next Inherited workbooks are full of hidden config and lookup sheets, and knowing the difference between hidden and very hidden is what turns "the sheet is gone" into a ten-second fix. If there is any chance you will reuse this, drop it into a small template tab right now: a labelled input area on the left and the formula beside it, checked once against the tool above. Next time the same question comes up, the answer is a single paste away instead of a rebuild from memory.
In Google Sheets
Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. If you take one thing from this page on “excel hidden sheets”, make it the habit rather than the keystrokes: set the problem up with labelled inputs, reference those cells, and let Excel do the recomputing. Bookmark the page for the syntax, but do the example once in a blank sheet and check it against the tool above — five minutes of hands-on practice fixes the method in memory far better than re-reading, and it surfaces the small snags while they are still harmless. After that the technique is genuinely yours: faster than searching for it again, and reliable enough to drop into work that other people depend on.
Common mistakes
- Concluding the sheet was deleted when it is very hidden and simply not listed in the Unhide dialog.
- Trying to unhide while the workbook structure is protected, which greys the command out with no explanation.
- Confusing hidden sheets with hidden rows or columns, which are unhidden from Home ▸ Format ▸ Hide & Unhide.
- Treating a hidden sheet as security — the data is fully readable to anyone who unhides it, or who opens the file as a zip.
- Unhiding one sheet at a time in older versions when a two-line macro does the lot.
Frequently asked questions
How do I unhide a sheet in Excel?
Right-click any sheet tab and choose Unhide, then select the sheet. In Microsoft 365 you can Ctrl-click to unhide several at once.
Why is my sheet not in the Unhide list?
It is "very hidden" — set that way in VBA. Press Alt+F11, select the sheet in the Project pane, and change Visible to -1 - xlSheetVisible in the Properties window.
Why is the Unhide option greyed out?
Either no sheet is hidden, or the workbook structure is protected. Check Review ▸ Protect Workbook and unprotect it first.
How do I unhide all sheets at once?
Microsoft 365 lets you Ctrl-click multiple entries in the Unhide dialog. Otherwise open the VBA Immediate window (Alt+F11, Ctrl+G) and run: For Each s In Sheets: s.Visible = -1: Next

Platform & version notes
- Several of those searches mention Google Sheets — and the good news is that "excel hidden sheets" works there almost identically: the formula syntax carries over unchanged, only the surrounding menus sit across the top of the screen instead of in a ribbon.
Can I do this in Google Sheets too?
Yes. "excel hidden sheets" carries over to Google Sheets with the same formula and almost the same steps — the menus are arranged differently, but the result is identical.
Why do people search for this in so many different ways?
Because the same task has many names. “sheets hidden in excel”, “hidden spreadsheet excel”, “hidden excel formulas” all point at the one operation explained on this page, which is why they all lead here.
