We don’t do very much testing with Office 2003 any more.

We plan to stop supporting Office 2003 quite soon – not in 3.3 (next release) but perhaps in v4: there are just too many big differences between 2003 and 2007+, and we’re finding a bunch more now that we’re testing eaDocX 3.3 with Office 2013.
Sorry for the bad news, but there’s only so many different release we can sensibly support, and our recent survey of eaDocX users suggested only a small minority are still stuck on 2003.
Despite this, I’ll pass-on the request for the eaXL team to have a look at this, and see if there’s a quick fix.
BTW: are you using all English-language versions of the OS and Excel ?

Hello

Just built a fresh VM with EA 10, eaDocX and Office 2003 and as you say it is possible to save files with the wrong extension although my version of XL didn’t complain.

If you use the “file | save as” menu it will name the file with the extension .xlsx which is incorrect 2003, I checked and looks like the internal format of the created file is correct, so by renaming the file from say bookxxx.xlsx to bookxxx.xls it should work.

Alternatively, if you use close the tab and save the file from the presented dialog it will save with a .xls extension.

In all cases the content appeared valid – so it is an extension issue. Interestingly we didn’t get a warning but they may due to differing configurations. It would be useful to know that by renaming you can open the file OK.

Regards
