import from excel

[dugaut]

I have an online database (not filemaker) that I can export changes from to excel to sync with my local filemaker database. The problem is that any field of a record that is changed goes to the same column. So there might be three lines in excel for the same person with each of the field changes in the same column. The column has a generic header. Each line has my primary key from my filemaker database so there is a way to link to the filemaker database.

Is there a possibility of writing a script to import this data?

My filemaker level is beginner. Thank You.
