Please help with e-mailing Excel for Mac files

Hi,

I am trying to send Excel for Mac document attachments in an e-mail from my Lion MBP and they are coming up as Text Edit documents which cannot be opened by me or the recipient They are labeled as Excel documents on my desktop. Does anyone know what I am doing wrong? My Excel version is 2008. Thanks for any help.

 

They are xlsx files - does that mean they are alias files? Do I need to rename? I always replace files after I update them and drop the extension to replace/save as original. I'm sorry- I'm a bit clueless about this and only use Excel at home intermittently. Please bear with me. Thanks for the help.

 

If you look at my saved files on my desktop, they are labeled as xlsx files. If I open a file and modify it, I always do it "save as" and drop the extension to the original file name so I don't have duplicate files, only the newest one. I will go back and look at them.

The strange thing is that when I went back and test-sent them to myself one at a time in an e-mail, they were sent in Excel, not Text Edit, form and I was able to open them. All except one.

 

I'm sure you're gritting your teeth about now and I do thank you for trying to help me!

----------

How do I add a dropped extension back? Just open the file, hit save, and let it do so with automatic extension?

 

It doesn't make sense because I opened them in Finder again and they are listed as .xlsx files. Will try sending through Excel rather than Mail. Perhaps it's a setting in Mail but I can't see how to adjust setting for attachments in Mail.

 

Thanks for the help. I renamed the files in Finder and then sent directly via Excel and it worked perfectly.
