Google sheet function for my small table

⭐ Generic proposal will be rejected. So read the details carefully. I need an excel/Google sheet expert. Here is the link for the table: https://docs.google.com/spreadsheets/d/1o5WlEROdxRFMemS8z1r6-qEiqWaccqOVSrjTdx-LriQ/edit?usp=sharing Some cells have two lines, I want a function that will do the following: 1. If a cell has two lines, delete the second line in the cell. 2. If a cell has ONLY one line, then nothing should be changed. It's a very small table and a quick job. I can only pay $2 max. If I liked your work, we would work long term. Please write "I'm okay with $2" so I know you read through. Happy bidding! Mohanad
