How can I open Office 2007 files in older versions of Office?

Summary: Office 2007 introduces a new XML based file format for its documents. There's a download for older versions off office to read and write the new format.

I have Microsoft Office 2003 on my computer. Friends of mine are sending me e-mail with attachments but are using Office 2007. Is there any way to convert Office 2003 to open e-mails from Office 2007?

Office 2007 introduces a new file format which is, of course, incompatible with previous versions of Microsoft office. So if you receive a document that someone has saved in Office 2007 format, but all you have is an earlier version of Office that can't read it, there are some steps you need to take.

But I also need to nit-pick one part of your question as well.

You asked "Is there any way to convert Office 2003 to open e-mails from Office 2007?" Emails should open just fine. Email messages are sent and received in a format common to all mail programs, and no conversion should be necessary.

You should also be able to save any attached documents. Again, attachments themselves are encoded into email in a standard way that has not changed. It's the format of the attached files themselves that has changed, and the program that's used to open the attached files needs to be able to handle their new file format.

You could, of course, ask your friends to save their files in the older format. This isn't the first time Office has changed formats, Microsoft Office has a fine track record of being able to save in older formats each time they change to new ones. Your friend could save his file in Office 2003 format before he sends it to you and you'd be able to read it like nothing changed.

What's unique this time is that Microsoft has made converters available for older versions of Office.

Download and install the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. (Take special care to read the Overview on that page - it's important that you have all High Priority updates from Microsoft Update installed before you install the converters.)

The compatibility pack works with Office 2000, Office XP and Office 2003.

i am having set of xlsx and pptx files, need to convert those to xls and ppt. but the command line is not doing any help.

I have downloaded the office compatibility pack and installed, then i tried for the xlsx to xls conversion

c:\Program Files\Microsoft Office\Office12>excelcnv -oice c:\xl.xlsx c:\xl.xls

it gives out a xl.xls but its just the copy of my input xlsx file when i open that file in the office 2000 it gives error. i just renamed the xl.xls to xl.zip, now i can see the xmls inside. so it just created the copy of my input file and renamed it to xl.xls.

Any help on this highly appreciated.

Thanks

I just installed Office Pro '07 over my old Office 2000. The new program comes up fine, but won't open my old docs. I did download all the updates & the service pack that is mentioned above. Still nothing. Any other ideas?

Hi Leo
I have Microsoft Office Word 2007 and my researcher in America is asking me to switch to a lower version so they can open an attachment I sent from Australia. Can you please help?
With thanks, Bev

Did the instructions in the article that you just commented on not help?

Article says pack only works as far back as Office 2000. I still use Office 97, and it's really all I need so I don't want to upgrade. Is there a compatibility pack available to work with Word 97?

Not that I'm aware of. After 12 years it might be time to upgrade.

Hello Leo, I have just installed all the Windows XP and Office Updates (also the "High Priority" of course). I installed also the recommended "Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats" But when I try to open an Excel 2007 file my office 2003 seems to open it but keep eating CPU time and running forever without let me read or work in the file... Can you help me, please? Thanks!
