Is it possible to import multiple Excel files into a database non-concurrently, e.g. I have an excel file on Monday that has 500 records, then I have another Excel file on Wednesday with 250 records, can I import them into the same database? Or, if I add
the records from the second Excel file into the first and import the new Excel file with 750 records, would any changes I made from within the CRM to the existing 500 records be kept?
Imports work as inserts unless you've first exported the data using the option to re-import so you get the records's unique identifier. Otherwise CRM wouldn't know which record to update.
