CHIN/AASLH has released their own spreadsheet file for Nomenclature which I am not sure match the Excel file from Rowman and Littlefield. They have also released an RDF file as well, which might be useful alternative to the XLSX format.
Could you review the CHIN/AASLH files for the Chenhall's Nomenclature to develop a caUtils mapping for the file? Thanks in advance.
Here is the link to the page to download the files:
