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 | required / optional | 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. |

In the result cell type =CONCATENATE( and click the first cell to join, such as A2.
Type a comma, then " " in quotes if you want a space (or any separator like ", ") between the items.
Type a comma and click the next cell, such as B2; add more comma-separated items as needed.
Close the bracket and press Enter to see the joined text.
Fill the formula down the column to join every row.
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. 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. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “concatenate with comma”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the outcome you expected 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. Check the referenced cells, argument order and result type in your workbook. Start with the worked example before changing an input, then compare the changed result with the calculation you expected. An error value or a result of a different type is a reason to inspect the inputs and arguments.
In Google Sheets
Google Sheets support for this task has not been verified. Check the function, arguments and workflow in the target product before transferring the example. Matching formula notation does not establish identical behaviour. Nothing on this page is behind a login or a download: the exact answer is at the top, and the detail below it is there for when you need it. That is the whole promise here — the answer first, and just enough context to make it stick. For “concatenate with comma”, keep the input cells and the result visible while you check the formula in Excel. Follow the worked example and change one input at a time. The steps explain the workbook calculation; this page does not run a live calculator for that task.
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.
