Description
This page says
use characters A through Z, numbers zero through nine, underscores, and periods.
On https://learn.microsoft.com/en-us/office/dev/add-ins/excel/custom-functions-json it says
contains only alphanumeric characters and periods
... unique within the scope of the file. That is, no two function objects in the metadata file should have the same id value
- Are lowercase letters allowed?
- If so, are these distinct? "MYFUNC" vs "myfunc"
- I noticed in the sheetx.xml the periods are converted to underscores. Does that mean "MY.FUNC" is not distinct from "MY_FUNC"?
