Data Transformation & Aggregation - Multiple cell values to columns

See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test (later on when you use the query on your dataset, you will have to change the source appropriately. If you have columns other than these, then delete Changed type step and do a Changed type for complete table from UI again)

Note - I am not sure whether you are picking up your project name from column 3 or column 1. Hence, in last step, I have kept both. You can delete one as per your requirement.
