How to Merge First AND Last Name in Excel

What this does

To merge text from several cells into one — first and last name, address parts, a code built from fields — you concatenate. The ampersand (&) glues values together, and you insert literal text like a space or comma in quotes between them. For many cells, TEXTJOIN takes a delimiter once and stitches the whole range, optionally skipping blanks. 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. Treat “merge first and last name in excel” 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 text operation that turns messy entries into clean, usable data into a method you can reuse, explain, and defend when the workbook leaves your screen.

A worked example

With "Lena" in A2 and "Bauer" in B2, =A2&" "&B2 returns "Lena Bauer" — the " " adds the space. To build a comma list from A2:A10, =TEXTJOIN(", ", TRUE, A2:A10) joins them all and the TRUE skips empty cells. The live preview above shows the joined result update as you type either name. Combining fields is the everyday glue of clean data — building full names, keys, file paths and labels from their parts. It is the inverse of splitting columns, and together they let you reshape any data set. 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

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. 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. Treat “merge first and last name 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, so values run together as "LenaBauer".
• Concatenating a number and losing its formatting — wrap it in TEXT() to keep currency or dates readable.
• Leaving the original columns in place when a downstream tool expects only the combined one.
• Using CONCATENATE (no delimiter argument) where TEXTJOIN would be far tidier.
