In Excel: use =CONCATENATE(text1, text2, ...) — it joins several text items into one string; in modern Excel the same job is done by CONCAT or simply the & operator.
Syntax
Arguments
| Argument | Description | |
|---|---|---|
text1 | required | The first text item to join — a cell reference or a string in quotes. |
text2, ... | optional | Optional further items to append, one after another; up to 255 in total. |

What this does
CONCATENATE glues together text from cells and typed strings into a single value. You list each piece as an argument and it appends them in order, with no spaces added — you insert any separators yourself as " " arguments. CONCATENATE is now legacy: Excel 2016 and later replace it with CONCAT (which also accepts whole ranges), and the & operator (=A1&" "&B1) does exactly the same thing more compactly. All three produce identical results. 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. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “concatenate columns in excel”. Start on a copy or a tiny sample, keep the affected columns visible, and compare the result with the tool above before you touch the real workbook. 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. The point is a text operation that turns messy entries into clean, usable data, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
A first name sits in A2 ("Maria") and a last name in B2 ("Klein"). To join them with a space between: =CONCATENATE(A2, " ", B2) returns "Maria Klein". The middle " " argument supplies the space; without it you would get "MariaKlein". The same result comes from =A2&" "&B2 or, in newer Excel, =CONCAT(A2, " ", B2). CONCATENATE remains common in older workbooks, but for new formulas the & operator or CONCAT is shorter and TEXTJOIN handles ranges, so reach for those when you can. 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
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. 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. Treat “concatenate columns in excel” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.
Common mistakes
- Forgetting the separator argument, so "Maria" and "Klein" run together as "MariaKlein" with no space.
- Expecting
CONCATENATEto accept a range likeA2:A6— it joins single items only; useCONCATorTEXTJOINto join a range. - Typing text without quotes, so words like a literal space or label trigger a
#NAME?error instead of appearing as text.
Frequently asked questions
What is the difference between CONCATENATE, CONCAT and &?
They all join text. CONCATENATE is the legacy function; CONCAT (Excel 2016+) replaces it and can also take whole ranges; the & operator, as in =A1&" "&B1, does the same thing with less typing. Use & or CONCAT in new work.
How do I add a space between joined values?
Insert " " (a space in quotes) as its own argument between the cells: =CONCATENATE(A2, " ", B2). For a comma and space use ", " instead.
Can CONCATENATE join a whole range at once?
No — it takes items one by one. To join a range such as A2:A6, use TEXTJOIN, which accepts a range and a delimiter, or CONCAT, which accepts ranges in newer Excel.
