It’s not very clear from the documentation, but as far as I understand, I don’t need the XLSFile entity in order to import entity records using an excel file, templates work fine even without the “reference to import objects”. So do I understand right that it is an optional entity, and excel importing process works fine without it? And if yes, what’s the purpose of this entity? Is it used for tracking the import activity (who, when, and using which file imported data)? How can I use XLSFile entity?
