Send column names from client to server for sorting data, but the client has camel case data but the server needs Pascal case data

I have to send column names from client to server for sorting data in a data table, but the client has camel case data and the server needs Pascal case data as the database columns are in pascal case.

I can either process the data at client side before sending or do it at the back-end.

What is the best approach to tackle the situation?.
