Convert Numbers to Excel on Windows: save an XLSX copy

You received a .numbers spreadsheet but need an Excel .xlsx file. A file extension change does not translate the tables. Read the original spreadsheet first, then export a separate Excel copy and check the data you need.

Start with the tables and cell values

Key, Pages & Numbers File Opener displays Numbers files locally without a Mac, Apple ID or upload. Its Pro Excel export carries over text, tables and cell values. Some shapes, charts and colors may be missing, so inspect the exported copy rather than assuming every visual element is retained.

Open the file with the app

Install Key, Pages & Numbers File Opener from Microsoft Store.
Double-click or drag in the .numbers file. For a document saved as a folder on a Mac, drag in the whole folder.
Use page navigation and zoom to check the tables and any notice about display differences.
Choose the Excel saving option (Pro) and select a destination for the .xlsx copy.
Check important cell values and any calculations you rely on in the exported copy, and review charts or shapes separately.

What is free?

Open .numbers files and view the table contents.
Zoom, move between pages, and select or copy text.
Read locally and offline without uploading the spreadsheet.

Save and export with Pro

Pro is a one-time purchase with no subscription. Check the Microsoft Store purchase screen for the current price.

Save Numbers as Excel (.xlsx), carrying over text, tables and cell values.
Save all or selected pages as PDF, save PNG pages and print.
Convert multiple files to PDF at once.

Limits and things that may be missing

Numbers charts and shapes may not appear in the viewer. Some shapes, charts and colors may be missing from the Excel export too.
This is a viewer and converter, not an editor for .numbers. It does not save back to the iWork format.
Password-protected files cannot be opened. Request an unprotected copy or PDF from the sender.
A first-page preview shown after a conversion failure is only a preview, not a complete spreadsheet export.

Tested Numbers files range from iWork '09 to 2025. If a chart is essential to your review, ask the sender for a separate reference copy and compare it with the conversion.
