[GNC] Exporting reports to spreadsheet

[George Riner]

The setting:

Windows 10
Gnucash 4.13

When I Export a report I've been supplying a windows extension of 
".ods". Which I assumed would cause that exported report file to open in 
some OpenDocumentSpreadsheet application, in my case: LibreOffice Calc.

But it doesn't do that. I double-click the file to open it in the 
default application and it opens in LibreOffice Writer.

Opening the exported report in a text editor I see that it's really an 
HTML file. And that, in fact, I can specify any windows extension I want 
when exporting the report from Gnucash, and it will always write out a 
file that contains HTML.

I think Windows is seeing ".ods" as something to open in LibreOffice, 
which starts reading the file and detects that it's HTML and then 
without any asking, renders the HTML in the exported report as a 
LibreOffice Writer document.

However, if I export a report and specify a file extension of ".xlsx" 
and then double click that to open it, then LibreOffice Calc starts up 
and offers to convert the HTML that's in that file to an actual 
spreadsheet which I can then save as a ".ods" file that opens in 
LibreOffice Calc.

I find myself in circles trying to find the straight path from Gnucash 
exported reports to LibreOffice Calc and can't seem to untangle the 
Windows/Gnucash/LibreOffice interactions to get this to happen.

Any Windows + LibreOffice users out that that get this working?
