How to Open a .Numbers File in Excel on Windows
A .numbers spreadsheet on a Windows PC is a locked box: Excel refuses it outright. Here are the routes in, starting with the fastest.
Fastest: convert to .xlsx online
Upload the .numbers file to the converter on this site — you get an Excel workbook with every cell value, plus a PDF of the original sheets exactly as designed. Free, no Mac or Apple ID needed.
iCloud.com (needs an Apple account)
Numbers for iCloud can open the file in a browser and export to Excel. It works if you have an Apple ID and do not mind the upload-open-export-download routine every single time.
What about formulas?
Numbers stores formulas in a proprietary structure, so conversions carry the computed values rather than live formulas — true of iCloud exports too in many cases. Check totals after converting, and rebuild key formulas in Excel if you need them live.
