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 “saving an excel file as a csv”, 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
Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. 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. Here is the takeaway for “saving an excel file as a csv”: copy the answer if you are busy, but if you have a spare few minutes, rebuild the example in Excel yourself with the tool above open beside it. That single pass — type it, run it, watch the result move when you change an input — is what turns a formula you found into a technique you trust. Keep your inputs labelled and referenced, never hard-coded, and the same sheet stays correct and auditable as it grows. Done that way, you will not need to look this up again, and you will be the person others ask.
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.
