.NUMBERS-TEF File Extension

There is only one file type that uses the .NUMBERS-TEF extension:

Numbers iCloud Document

Numbers iCloud Document

Spreadsheet file created by Numbers, Apple's spreadsheet program included in the iWork suite; used as the save format when the user chooses to save the spreadsheet to iCloud.

Even though iCloud uses the NUMBERS-TEF extension, it shouldn't be an issue for users. When you open a spreadsheet on your Mac OS X or iOS version of Numbers, the spreadsheet will still load properly.

NOTE: Numbers spreadsheets saved on the local computer use the .NUMBERS extension.
