Hi,
My name is Marlou and you can call me Maloyski since this is the name they usually called me!
Based on the description you provided, your are looking for a excel expert to group and create subtotal with nice UI design? I believed I can help you with that. Can you share to me the mapping details for me to visualize your requirements?
Just let me know if this is ok with you and hoping you will be my first client here in upwork.
Best Regard,
Maloyski
