Top notch content.Hats off for compiling such a detailed video .

I have an inquiry regarding setting up a logic in Power BI that allows users to select colours based on Excel input data, affecting the colour of column headers in a dynamic fashion. The idea is for the system to recognise numerical inputs - with '1' representing green, '2' signifying blue, and '3' indicating red - and to modify the column header colour accordingly. The dataset is updated on a monthly basis, which calls for a logic where changes made in Excel are seamlessly integrated and mirrored in Power BI. My focus is solely on columns, as my column tables don't include rows. Despite the unique nature of this user requirement, which has kept me puzzled for nearly a week, I'm reaching out to see if you could provide guidance or solution. Thanks

content is really amazing and useful sir.. but throughout the video it seemed like you are just reading your notes for us.. which was really boring. I am saying this because I was a trainer once, learners are really of different Kind, some can understand just reading them self, some can by hearing /videos or telling . so energy while explaining something really matters so that we can keep the audience connected. because goal isnt just to make a useful video.... I m Sorry if anything you dnt like ....
