Convert Numbers to CSV — no Mac required
.numbers is Apple's spreadsheet format — nothing on Windows opens it. CSV is the plain-text format every spreadsheet app, database and script reads. Drop your files in and they are converted entirely in your browser — one CSV per table, UTF-8 with BOM so Excel opens them correctly on double-click. Your files never leave your device.

one or many at once — up to 200 files per batch
Your files never leave your device — everything is parsed locally in your browser.

What you get
One CSV per table
A Numbers document holds sheets, and each sheet can hold several tables. Every table is exported as its own clean CSV — values only, exactly as Apple Numbers last computed them.
Excel-friendly encoding
Files are written as UTF-8 with a byte-order mark and CRLF line endings, so Excel opens them correctly on double-click — accented and non-English text included. Fields with commas, quotes or line breaks are quoted per RFC 4180.
Private by design
The CSV is assembled on your machine from the parsed spreadsheet. Nothing — not the file, not the data, not the output — is sent anywhere. Safe for financial or confidential data.

Frequently asked questions
Why CSV instead of Excel?
CSV is the lowest-common-denominator data format: every spreadsheet app, database, statistics tool and programming language reads it. If you just need the numbers out of a .numbers file — for import, analysis or a script — CSV is the fastest path. If you need real Excel workbooks with typed dates and multiple worksheets, use the Numbers to Excel converter instead.
What happens to multiple sheets and tables?
A Numbers document can hold several sheets, each with several tables — CSV has no concept
of sheets, so every table becomes its own CSV file, named
file-sheet-table.csv. A single-table document downloads as one
.csv; documents with several tables download as a small zip.
Are formulas preserved?
CSV holds values, not formulas — each formula cell is written as the value Apple Numbers last computed and stored in the file, exactly like copy → paste special → values in a spreadsheet app.
Will Excel open the CSV correctly (accents, non-English text)?
Yes. The files are UTF-8 with a byte-order mark — the one variant Excel for Windows sniffs correctly on double-click — with CRLF line endings and RFC 4180 quoting for fields that contain commas, quotes or line breaks.
Is it really private? These are financial files.
Yes. The .numbers parser is JavaScript running inside your browser tab and the CSV is assembled there too — no server ever sees the file, the data, or the output. Open your browser's Network tab while you work and watch: no content is transmitted. See the privacy policy.
What exactly does the $9.99 license cover?
Unlimited batch exports, forever, for one user: select any number of loaded spreadsheets and download them as CSV files packed into one zip. The same key also unlocks batch Excel export on the other pages of this site. It's a one-time payment, not a subscription.
