I have the poblem EVEN when using a NEW Excel worksheet directly within Excel 2013 (on the same Windows OS).
Or when reimporting to Excel a worksheet initially created with Excel 2013 but saved/shared online (not on Office Online, but on Google Docs).
Office does not offer the user any UI option to revert this "compability tweak" applied blindly on loaded documents, and does not even notice the user about the incompatibility.
You may think that this is a bug of Google Docs, but this is not. Office applies some new invisible requirements on documents and breaks them without notice.
I consider this bug to be an unfair trick to promote only the Microsoft online cloud, and break other competing solutions.
This is also clearly a bug for the conformance with the ODF format (that Office 2013 officially supports including as a default preference for users, instead of the Ms Office XML formats). This is also a bug for compatibility with all other past versions
of Office on Windows and MacOS.
When Microsoft advertizes users tht it offers a great solution for interoperability, this is wrong in this case (and in fact even if this is a "feature", this is not documented anywhere by Microsoft, for users or for Office developers, or documented in
an obscure area difficult to find).
As always, Microsoft is leading the championship of incompatibility enve with its OWN solutions. It constantly changes things and creates new incompatibilities, and promotes clear bugs into features, and then refuses to change things because it "could
break" applications (in fact these bugs constantly break more things each time they appear, than what keeping them will solve). Ms Office 2013 is still a very minor software in our world, and it should live in a world where there are MUCH more solutions (for
various versions of Windows or Mac OS, or for users of other past versions of Office, which are still officially maintained by Microsoft, or for competing cloud solutions or data formats like ODF).
Microsoft should NEVER create an internal "compatiblity" tweak without allowing the user to disable it by some UI option. If the new "feature" changes things where it is actually a bug (like here), this bug should be corrected and disabled by an UI. Note
that ALL Office documents are tracking internally the version of the software used to create it initially.
Here the only cause of the problem is that the "conditional format" dialogs forgot to include a tab or pane for the alignment settings (those settings whuch are available internally, but also within the interface for unconditional cell formats). This stupid
bug is clearly something that has been forgotten in the new UI design of Excel in Office 2013.
