Numbers to CSV Converter

Open Apple Numbers spreadsheets and save their tables as CSV, entirely inside your browser

Numbers stores a spreadsheet as a package of Apple’s own binary parts, which is why a .numbers file will not open in Excel, Google Sheets, or a plain text editor. This page reads that format directly and rebuilds the cells: text, numbers, dates, durations, true/false values, and the results Numbers calculated.

Every sheet and every table on it is listed before you download anything, together with a short report of what a CSV file cannot carry across. Your document is opened by this page on your own device — it is never uploaded.

Accepts NUMBERS. Up to 20 files; combined maximum: 192 MiB. Files above this hard limit are rejected before local processing.

Your spreadsheets are read by this page itself. Nothing is uploaded, and the converter keeps working offline.

How to Convert

  1. Drop one or more .numbers documents onto the page, or browse for them on your device
  2. Watch each file convert locally, then choose a sheet and table to preview
  3. Set the delimiter, quoting, line endings and encoding your next tool expects
  4. Download the table you are previewing, or every table as a ZIP with a manifest

Features

  • Reads the spreadsheet data inside a .numbers package, cell by cell
  • Preview every sheet and every table before you download anything
  • Export the table you are looking at, or all of them as separate CSVs in one ZIP
  • Choose delimiter, quoting, line endings, and UTF-8, UTF-8 BOM or Latin-1 encoding
  • Keeps numbers exact, writes dates as ISO 8601, and preserves blank cells and Unicode text
  • Converts a batch of documents with pause, cancel and retry for each file
  • Reports what a CSV cannot hold — charts, images, comments and formatting — before you export
  • Runs entirely in your browser, so documents never leave your device and it works offline

Use Cases

  • Move a spreadsheet out of Numbers into a tool that only reads CSV
  • Send a colleague on Windows the data from a Mac-only document
  • Load Numbers data into a database, a script, or an analytics pipeline
  • Split a document with several sheets into one CSV file per table
  • Convert a folder of Numbers documents in one pass and keep a record of the output

Frequently Asked Questions

Do I need a Mac or a copy of Numbers?

No. The converter reads the .numbers format itself, so it works on Windows, Linux, Android and ChromeOS as well as on a Mac, without Numbers installed.

Is my spreadsheet uploaded to a server?

Never. The document is opened by code running on this page, in a background worker on your own device. Nothing is sent anywhere, and the page keeps working with no network connection.

What happens to formulas?

Numbers saves the value each formula produced, and that calculated value is what the CSV receives — the formula text itself is not written to the file. If you only want the data you typed, switch formula cells to "Leave empty" in the output options.

What about charts, images, comments and merged cells?

A CSV file holds rows of plain values, so charts, images, text boxes, comments, colours and fonts cannot come across. The report shown before you download counts what your document contains. Merged cells keep their value in the first cell of the block, and the cells the block covered are written empty.

Can I convert several documents at once?

Yes. Add up to 20 documents and they convert a few at a time so your browser stays responsive. You can pause the queue, cancel or retry a single file, download any finished file on its own, or take everything as one ZIP with a manifest listing each CSV.

Which versions of Numbers does it read?

Documents saved by the versions of Numbers in use today, on Mac, iPad, iPhone or iCloud. A document saved by Numbers ’09 or earlier uses a different format: the page tells you so and explains how to re-save it, rather than producing a file that looks converted but is not.

Why are dates written like 2026-07-04?

ISO 8601 sorts correctly and is read the same way in every country, so it is the safest form for a file that will be imported elsewhere. Numbers stores the display format separately from the value, so that styling is not part of the data a CSV can carry.

Can this make an Excel workbook instead?

This page writes CSV. If you need .xlsx, convert here and then build a workbook from the CSV with our CSV to Excel converter.
