In Excel: while editing a cell, press Alt+Enter (Ctrl+Option+Enter or Cmd+Option+Enter on Mac) to drop a hard line break at the cursor; in a formula, join text with CHAR(10) — like =A1&CHAR(10)&B1 — and turn on Wrap Text so the break shows.

Double-click the cell (or press F2) to enter edit mode and place the cursor where the break should go.
Press Alt+Enter on Windows, or Ctrl+Option+Enter / Cmd+Option+Enter on Mac, to insert a hard line break.
To break by formula, write =A1&CHAR(10)&B1, joining each part with &CHAR(10)&.
Select the cell and turn on Home ▸ Wrap Text so the line break is actually displayed.
What this does
A line break is a manual hard return placed at a chosen point inside one cell, unlike Wrap Text which auto-flows long text to the column width. You type the first part, press Alt+Enter, and the cursor moves to a fresh line within the same cell while the value stays a single cell. In a formula you build the break with CHAR(10), the line-feed character — for example =A1&CHAR(10)&B1 stacks the contents of A1 and B1 on two lines. Either way you must enable Home ▸ Wrap Text on the cell, otherwise the break is stored but rendered as a single run. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. Treat “second line in excel cell” 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 cells shows up while it is still harmless. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. 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
Double-click a cell, place the cursor between two words, and press Alt+Enter — the text after the cursor drops to a new line within the same cell. To do it by formula instead, enter =A1&CHAR(10)&B1 where A1 is "London" and B1 is "NW1 6XE"; with Wrap Text on, the cell shows "London" on the first line and "NW1 6XE" on the second. A line break lets you stack an address, a label and a code, or any multi-part entry tidily inside one cell — keeping the data in a single cell while reading like several lines. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.
In Google Sheets
If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. 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 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 “second line in excel cell”, 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
- Inserting CHAR(10) but leaving Wrap Text off, so the break is stored yet shown as one continuous line.
- Pressing plain Enter, which leaves the cell and moves down instead of breaking inside it.
- Expecting the row to grow on its own — reapply Home ▸ Format ▸ AutoFit Row Height if it stays clipped.
- Confusing a manual break with Wrap Text auto-wrap; the break sits at your chosen point, wrapping flows to the column edge.
Frequently asked questions
What is the shortcut for a line break in a cell?
Alt+Enter on Windows, and Ctrl+Option+Enter or Cmd+Option+Enter on Mac, while you are editing the cell.
How do I add a line break in a formula?
Join your text with CHAR(10), the line-feed character — for example =A1&CHAR(10)&B1 — then turn on Wrap Text so the break appears.
Does this work in Google Sheets?
Yes. Press Alt+Enter (or Ctrl+Enter) to break manually, and use CHAR(10) in formulas exactly the same way.
