Char Function in Excel

What this does

CHAR turns a number into the character it represents and CODE does the reverse. They matter for two everyday jobs. Inserting a line break inside a formula-built string requires CHAR(10) on Windows, since you cannot type Alt+Enter inside a formula — and the cell must have Wrap Text switched on or the break stays invisible. And diagnosing invisible characters requires CODE: pointing it at the first character of a stubborn value tells you exactly what is there, which is usually 160 (non-breaking space) or 10 (line feed). Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. For “char function 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 formula change, and only then apply the same setup to the full sheet. 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 is what makes a text operation that turns messy entries into clean, usable data useful in real work: repeatable, auditable, and not dependent on memory or luck.

A worked example

Building a multi-line address in one cell: =A2 & CHAR(10) & B2 & CHAR(10) & C2, with Wrap Text enabled on the cell. Diagnosing a value that will not match: =CODE(LEFT(A2,1)) returning 160 identifies a non-breaking space. Removing it once identified: =SUBSTITUTE(A2, CHAR(160), " "). CHAR(10) is the only way to build a multi-line cell from a formula, and CODE is the only way to identify what invisible character is breaking a match. 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

Everything above works in Google Sheets too. Excel and Sheets share the formula syntax used here; only the surrounding menus are arranged differently. That portability is deliberate — learn it once and it follows you between the two tools and across Windows and Mac. Nothing on this page is behind a login: the tool runs entirely in your browser, the formula is shown in full with one-click copy, and the steps work the same on Windows and Mac. That is the whole promise here — the exact answer, a way to prove it on your own numbers, and just enough context to make it stick. The short version of “char function in excel”: the answer is at the top of this page, the tool proves it on your own numbers, and the sections above explain why it holds so the next variation does not stump you. Excel rewards people who reference cells instead of typing values and who keep inputs separate from formulas, because that is what makes a result you can audit months later. Build it once, deliberately, with the live tool as a check, and you convert a one-off lookup into a reusable skill — which is the whole point of learning the why and not just the what.

Common mistakes

• Using CHAR(10) without enabling Wrap Text, which makes the line break invisible and looks like the formula failed.
• Using CHAR(10) on a Mac where CHAR(13) is expected in some contexts; test which one your file needs.
• Passing 0 or a number above 255 to CHAR, which returns #VALUE!.
