How to Convert Excel to CSV

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. 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 “convert excel to csv”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the tool above before you touch the real workbook. 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. The point is a data step that keeps your analysis trustworthy, but the practical win is that someone else can open the file and understand what happened without asking you.

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. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.

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. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. If you take one thing from this page on “convert excel to csv”, make it the habit rather than the keystrokes: set the problem up with labelled inputs, reference those cells, and let Excel do the recomputing. Bookmark the page for the syntax, but do the example once in a blank sheet and check it against the tool above — five minutes of hands-on practice fixes the method in memory far better than re-reading, and it surfaces the small snags while they are still harmless. After that the technique is genuinely yours: faster than searching for it again, and reliable enough to drop into work that other people depend on.

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.
