In Excel: select the column, then Data ▸ Text to Columns ▸ Delimited, tick the separator (space, comma, etc.) and Excel spreads each piece into its own column; Fixed width splits at set character positions instead.

What this does
Splitting takes one column whose cells each hold several pieces of information and spreads those pieces across separate columns — a full name in one cell becomes a first-name column and a last-name column. The main tool is Data ▸ Text to Columns: in Delimited mode you pick the character that separates the parts (a space, comma, tab or semicolon) and Excel breaks every cell at that character; Fixed width instead cuts at character positions you set, for data with no separator. This is the exact inverse of combining columns. 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. For “split data 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 cells change, and only then apply the same setup to the full sheet. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. 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
"Ada Lovelace" sits in A2 and you want first and last name apart. Select column A, choose Data ▸ Text to Columns, pick Delimited, tick Space as the delimiter, and the preview shows "Ada" and "Lovelace" splitting into two columns; finish and "Ada" lands in A2 with "Lovelace" pushed into B2. For a one-off, type "Ada" in B2, press Ctrl+E (Flash Fill) and Excel separates the rest. As a live formula, =TEXTBEFORE(A2," ") returns the first name and =TEXTAFTER(A2," ") the last. Splitting a column untangles data that arrived crammed together — names, addresses, codes, exported CSV fields — into clean separate columns you can sort, filter and look up. It is the everyday inverse of combining columns, and the pair let you reshape data either way. 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. Keep this page bookmarked for the next time the same question comes up. Better still, rebuild the example once in your own sheet — doing it yourself, with the tool above to check against, is what turns a copied formula into a technique you own. The short version of “split data 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
- Forgetting to leave empty columns to the right, so Text to Columns overwrites the data already there.
- Picking the wrong delimiter — choosing comma when the names are separated by a space leaves them unsplit.
- Using Delimited for fixed-position data (or vice versa), so the cuts land in the wrong place.
- Splitting a column of numbers and letting Excel reformat them as text or dates — set the column data format in the wizard if it matters.
Frequently asked questions
How do I separate first and last name into two columns?
Select the name column, Data ▸ Text to Columns ▸ Delimited, tick Space, and Finish — the first name stays put and the last name moves to the next column. Ctrl+E (Flash Fill) does it from one typed example too.
Text to Columns or Flash Fill?
Text to Columns is a one-pass wizard with delimiter control; Flash Fill (Ctrl+E) learns from an example and is quickest for a single, regular pattern. Neither updates live — for that use =TEXTBEFORE/=TEXTAFTER.
How do I split without overwriting the next column?
Insert blank columns to the right first, or run Text to Columns into a separate destination, so the pieces have empty cells to fill instead of replacing existing data.
