Add Headers to TXT file received by FTP with Spreadsheet node

Questions

Hi guys, I am receiving a file on an SFTP server, getting it to n8n and sending read data to speadsheet node. However the txt file comes without headers and I really need to add some headers to this file so that the first line is not taken as headers.

Below is my workflow, and an example of the first 2 lines of the txt file (separated by ;):

0100104370;1089626;CO-CAPME48;;;;;;;;;;;;;;;;;;;;99;;;;;COP;E;1;A;CO6000067;2018-10-05;9999-12-31;10;5990;;;B;1;X;X;01;1;0100104370;0100104370;0100104370;;0100104370;90056622;0100104370;;;;;;;;;;;;;
