How to Convert Apple Numbers to CSV

Numbers (.numbers) is Apple's spreadsheet format, only natively openable on Mac and iOS. CSV is the universal data exchange format. Converting Numbers to CSV makes your spreadsheet data importable into Excel, databases, BI tools, and any system outside the Apple ecosystem.

Step-by-step instructions

  1. 1

    Open the file in Numbers

    Double-click your .numbers file on a Mac to open in Numbers. On iPhone/iPad, tap the file in Files app. The spreadsheet opens with all sheets visible.

    Go to converter
  2. 2

    Export to CSV

    Mac: File → Export To → CSV. iOS: tap the three-dot menu → Export → CSV. Choose options: include headers, encoding (UTF-8 with BOM for Excel compatibility).

  3. 3

    Save and use the CSV

    Save the .csv file and open in Excel, Google Sheets, or import into your database. Each sheet of the Numbers file becomes a separate CSV.

Frequently asked questions

Can I convert Numbers to CSV without a Mac?
iCloud.com — go to icloud.com, sign in with your Apple ID, open Numbers in the browser, upload your .numbers file, then File → Download a Copy → CSV. Works on Windows or Linux without any Apple software installed.
Will formulas convert?
No — CSV stores values, not formulas. The CSV contains the calculated results. If you need formulas, export to XLSX instead, then convert to CSV in Excel only when you're ready for plain data.
How do I convert multiple sheets at once?
Numbers exports each sheet as a separate CSV file when you choose CSV export. The file is saved as a folder containing one CSV per sheet, named after each sheet's name.
