As far as I know, Mike, there is no direct conversion - copy and paste it is, I am afraid.

The direct conversion might be possible with Ndless

In fact, usually, we don't touch the silly obfuscated and badly
documented TNS format) with Ndless :)

Since we can't count on TI ever providing that kind of converter tools,
or some documentation:
* third-party reverse-engineering of the Nspire spreadsheet format;
* format conversion (because the syntax used by Excel/LibreOffice
Calc/whatever is certainly different from that used by the Nspire);
* usage of Luna ( available at
http://www.ticalc.org/archives/files/fileinfo/441/44113.html ,
http://tiplanet.org/forum/archives_voir.php?id=3701 ), possibly after
expanding its functionality
