Unfortunately I could not solve that until now.
Maybe it becomes clearer if I ask like this:
How can I export some WL-data (say a string) together with a WL-image (generated from a graphics or anything else) on one sheet of an Excel-2007ff (.xlsx) workbook?
Thanks, Chad. This works indeed. But I cannot see how to get control over the sheet names. And how can I mix different data on one sheet? For example a header line and a graphics? Like in my example above.
Here is one way to do it:
aTable = Table[{x, x^2}, {x, 10}]; aGraphics = ListPlot[aTable]; xfile = Export["exported_tmp.xlsx", {"Sheets" -> aTable, "Images" -> aGraphics}, "Rules"]
