In Excel: select the cells, then Home ▸ Merge & Center (Alt H M C on Windows). To avoid the data-loss trap, prefer “Center Across Selection” instead.

Select the cells you want to merge.
On the Home tab, click the arrow next to Merge & Center and choose the merge type.

Prefer Format Cells ▸ Alignment ▸ Center Across Selection when you only need centred text.
What this does
Merging joins two or more cells into one larger cell, usually to centre a title across columns. It is a visual tool, not a data one: a merged block keeps only the top-left value and discards the rest, and it breaks sorting, filtering and many formulas. That is why experienced users reach for “Center Across Selection” when they only want the look without the side effects. 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. For “center across selection 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 cells 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 workspace setting that makes a big sheet comfortable to navigate useful in real work: repeatable, auditable, and not dependent on memory or luck.
A worked example
To centre a report title over columns A to D, select A1:D1 and click Merge & Center on the Home tab. The text sits centred across the four columns. But if A1:D1 had four values, only A1 survives. The safe alternative: select the range, open Format Cells ▸ Alignment ▸ Horizontal ▸ Center Across Selection — same look, no merge, no lost data. Merging makes headers and titles look polished, but used inside a data range it quietly sabotages sorting, filtering and formulas. Knowing the safe alternative keeps your sheet both tidy and functional. If this is something you do often, add the command to the Quick Access Toolbar (right-click it on the ribbon and choose Add to Quick Access Toolbar) or learn its shortcut, so next time it is one click instead of a hunt through the menus.
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. If you take one thing from this page on “center across selection excel”, make it the order of checks rather than the individual clicks: confirm what is selected, apply the step, and look at the result before moving on. That small routine is what keeps Excel work predictable when the same task comes back in a slightly different workbook.
Common mistakes
- Merging cells that hold data — everything except the top-left value is silently deleted.
- Merging inside a table you later sort or filter, which Excel will refuse or break.
- Using merged cells where a formula needs to reference each one individually.
- Forgetting that merged cells complicate copy-paste and keyboard navigation.
Frequently asked questions
Why is sorting greyed out after merging?
Sorting and filtering cannot reorder rows that span a merged block. Unmerge the cells, or use Center Across Selection, to restore those features.
How do I merge without losing data?
You cannot keep all values in a true merge. Combine them first with =A1&" "&B1, or use Center Across Selection for the visual effect only.
Does Google Sheets merge the same way?
Yes — Format ▸ Merge cells offers the same options, with the same caveat that only the top-left value is kept.

Platform & version notes
- If you are on a Mac, nothing here changes except the modifier key: swap Ctrl for ⌘ in every shortcut, and use the Windows/Mac toggle at the top of the page so the keystrokes shown match the keyboard in front of you.
- Some variants pin a specific edition (365). The method above is stable across recent Excel releases — older versions only differ in where a ribbon icon sits, not in what the steps achieve.
Does this still work in older versions?
It does. The approach has been stable across recent Excel releases; only the ribbon icons have shifted cosmetically, so the steps above still apply.
How is it different on a Mac?
Only the keys. Press ⌘ where Windows uses Ctrl; the menus, formulas and result for "center across selection excel" are the same on macOS as on Windows.
