In Excel: use File ▸ Save As (or Save a Copy), pick "CSV UTF-8 (Comma delimited) (*.csv)" as the file type, and save — only the ACTIVE worksheet is exported, and formulas are replaced by their current values.
Choose a .xlsx file — the first worksheet is converted.
What this does
CSV is plain text: one row per line, cells separated by a delimiter. Saving as CSV therefore throws away everything that is not a value — formatting, formulas, charts, extra sheets, and data types. That is usually the point (maximum compatibility), but it means the conversion is one-way: keep the original .xlsx if you still need the workbook features. 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. For “create a csv file from 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 data step that keeps your analysis trustworthy useful in real work: repeatable, auditable, and not dependent on memory or luck.
A worked example
A workbook has the active sheet Orders with 200 rows and a Pivot sheet. Saving as CSV UTF-8 produces orders.csv with exactly the 200 rows of Orders as text — the pivot sheet, the currency formatting, and the =SUM() row all disappear; the SUM cell contains its last calculated number instead. CSV is the lingua franca of data import — CRMs, banks, databases, and scripts all accept it. Exporting cleanly (UTF-8, right delimiter) avoids broken umlauts and shifted columns on the receiving side. 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. 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 “create a csv file from 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
- Picking the legacy "CSV (Comma delimited)" instead of CSV UTF-8, which mangles ä, é, and other non-ASCII characters.
- Expecting all sheets in the file — CSV holds exactly one.
- Re-opening the CSV and being surprised formulas are gone; they were exported as values.
- Leading zeros (007) lost when the CSV is re-opened in Excel — import the column as text instead.
Frequently asked questions
Why does my exported CSV show semicolons instead of commas?
Excel uses your system list separator. On many European locales that is ";". The converter above lets you pick comma, semicolon, or tab explicitly.
How do I export every sheet of the workbook?
Save each sheet separately (CSV is single-sheet), or use a script/Power Query to batch-export.
Why do my dates look like numbers (e.g. 45443) in the CSV?
Date cells store serial numbers; some exports emit the raw serial. Use our date serial converter, or format the column as text dates before exporting.
