iphone wont open xls email attachment

I need to be able to open .xls email attachments on my iphone 3GS from a major customer which i receive regularly but get the following error:
*This document can't be viewed. An error occured while reading the document.*
I can open the same .xls file on my macbook pro using excel:mac2008 although i get a message first 'file error data may have been lost' which i just need to click ok and the file opens normally.
I have tried downloading 'Quickoffice' to the iphone but makes no difference.
My previous phone with windows mobile opened the same .xls attachement with no problem.
I need to solve this, please can anyone help?

3gs, iPhone OS 3.1.2

XLS documents are supported as attachments to view:

Viewable document types: .jpg, .tiff, .gif (images); .doc and .docx (Microsoft Word); .htm and .html (web pages); .key (Keynote); .numbers (Numbers); .pages (Pages); .pdf (Preview and Adobe Acrobat); .ppt and .pptx (Microsoft PowerPoint); .txt (text); .rtf (rich text format); .vcf (contact information); .xls and .xlsx (Microsoft Excel).

Is the file password protected? If so, it won't open since the iphones support is only as a viewer.

I ran into a similar problem. I have a vendor that embedds HTML data in an xls file and just hits save. Problem is that the iPhone viewer tries to open it as xls instead of html (and says invalid file format).

I opened the file in Excel 2003 (windows version gasp), then clicked on File > Save As and low and behold it's default was .html (indicating that is how it was saved orginally). I changed it to a normal Excel Workbook (.xls) saved, and re-emailed it and it worked fine. Also it works if I just change the file extension to .html.

So for whatever reason the iPhone viewer cannot handle an html page saved with an xls extension.

Since your sender will not change his ways, you could write some code to intercept the email, change the file extension, and resend it.
