I am working on a interface that allows a user to import his contacts (read millions of contacts) using a .csv file.
I need to extract the following fields from the .csv file
The csv I am speaking about can contains 3 columns or even more and these columns can have different column names, for example
- mail / contact address / email
- name / fname / first
so different user may have csv files with different headers, as shown above.
So before uploading the data from csv, I need to design an interface that will read the csv headers and present a column mapping like interface where the user can map my systems column (which are email_adrress, first_name and last_name) with his column.
Below is what I have came up with. Need some help in identifying how easy or difficult will it be for user to understand this ui.
Suggestions/ideas are also welcomed.
