Trying to open the attached spreadsheet in 1.12.6 and git. Geting message box with Sheet1!F36 : Encountered uninterpretable "ext" extension in namespace "{64002731-A6B0-56B0-2670-7721B7C09600}" instead of spreadsheet. Spreadsheet was written by Excel on OS-X, and is readable in libreoffice calc. It started out in libreoffice.
Nothing got attached.
Created attachment 273669 [details] Spreadsheet that does not open in gnumeric
Encountered uninterpretable "ext" extension in namespace "{64002731-A6B0-56B0-2670-7721B7C09600}" simply means that the xlsx file contains an "ext" element that in xlsx is used to attached arbitrary undocumented content. It seems that Excel likes to attach some of that to any file its creates. Since one cannot know what the content is intended to do, this message may be unnecessary or indicate that information is lost.
Note that the attached file opens for me just fine (it just presents the ext warning first). There appears to be a sheet object that is not properly understood.
The complete list of warnings I see on the console is: Unexpected element 'a:xfrm' in state : theme -> objectDefaults -> spDef -> spPr Unexpected element 'a:custGeom' in state : theme -> objectDefaults -> spDef -> spPr Unexpected element 'a:solidFill' in state : theme -> objectDefaults -> spDef -> spPr Unexpected element 'a:ln' in state : theme -> objectDefaults -> spDef -> spPr Unexpected element 'a:effectLst' in state : theme -> objectDefaults -> spDef -> spPr Unexpected element 'a:extLst' in state : theme -> objectDefaults -> spDef -> spPr Unexpected element 'a:xfrm' in state : theme -> objectDefaults -> lnDef -> spPr Unexpected element 'a:custGeom' in state : theme -> objectDefaults -> lnDef -> spPr Unexpected element 'a:solidFill' in state : theme -> objectDefaults -> lnDef -> spPr Unexpected element 'a:ln' in state : theme -> objectDefaults -> lnDef -> spPr Unexpected element 'a:effectLst' in state : theme -> objectDefaults -> lnDef -> spPr Unexpected element 'a:extLst' in state : theme -> objectDefaults -> lnDef -> spPr Encountered uninterpretable "ext" extension in namespace "{7523E5D3-25F3-A5E0-1632-64F254C22452}" Unexpected element 'mx:ArchID' in state : workbook -> extLst -> ext Unexpected element 'c:overlay' in state : chartSpace -> chart -> title Unexpected element 'c:minorGridlines' in state : chartSpace -> chart -> plotArea -> valAx Unexpected element 'a:prstDash' in state : chartSpace -> chart -> plotArea -> valAx -> spPr -> ln -> solidFill Unexpected element 'c:overlay' in state : chartSpace -> chart -> plotArea -> valAx -> title Unexpected element 'c:overlay' in state : chartSpace -> chart -> plotArea -> valAx -> title Unexpected element 'c:overlay' in state : chartSpace -> chart -> legend Sheet1!F36 : Encountered uninterpretable "ext" extension in namespace "{64002731-A6B0-56B0-2670-7721B7C09600}" Unexpected element 'mx:PLV' in state : worksheet -> extLst -> ext
> used to attached arbitrary undocumented content arbitrary, yes. undocumented, not sure. I have seen some documentation of ext stuff on microsoft.com (or msdn.com or whatever).
I have added some noise reduction to the grammar in my tree, but I cannot commit from. Jean, can you take a look here? The graph appears to load just fine when you look at its properties (modulo things like the title being black on black). However, nothing shows.
I see two issues: the first is that the title is black text over black background. The second is the Chart manual position. We might have a bug there. Need more investigation.
The chart is loaded with auto size and manual position, but still use the manual size (which is set to 0x0) so we don't see anything.
We do a half-decent import of this graph now. And the pointless warning about "ext" has been shut up. This problem has been fixed in our software repository. The fix will go into the next software release. Thank you for your bug report.
