I have done some preliminary work with a spreadsheet within cell ranges that can be copied and pasted into the Import Text gramplet if TSV delimiter dialect has been selected. (An added benefit to the Import Text is that the input data is visible before and after being processed.) A spreadsheet (or its CSV export file) is more universally accessible than GEDCOM. Few computer users have GEDCOM inspection or editing tools installed.
There are some hiccups. It is hard to explain Principle and Selection of the Tab delimiter dialect. (The difficulty is in regards to both the purpose and accessing the interface.) Also, the CSV field names have some idiosyncrasies. (Such as the “Death Cause” is actually the “Death Description” for a Death event “type”, not the description for a “Other → Cause Of Death” Event type. And the Date for a Place is ambiguous. Is it the date of existence for the Place name? Or the date of enclosure?)
