Comparing exports from different account versions

When comparing account exports, first check the export dates, format versions, and field definitions. A renamed field does not by itself mean information was added or removed. This thread is for questions about comparing archive structures without sharing private records.

Would it make sense to compare the field descriptions before trying to line up the two files?

I'd find a small example with invented field names helpful, especially where one old field becomes two new ones.

The distinction between a renamed field and missing information is useful. I'd want to note both possibilities before treating an empty column as a deletion.
