get angle from coord.

[sanju2323]

I'm trying to find the angle from coord. And which direction to the turns right or left.

Thank you in advance

How much of this is a trigonometry question, and how much of it is an Excel question? It seems like it should be relatively simple trigonometry at each point. If you understand the trig and can explain it to us, then we should be able to help you program that into Excel. If you need help with the trig, I will have to look at this closer.

It seems to me that the heart of the solution will be the ATAN2() function (https://support.office.com/en-us/art...8-c96b3a565033 ). Perhaps a "translation and rotation" step so that each point can be seen as the center of a "unit circle" with the previous segment along the x axis. In keeping with standard trig convention, left turns will be positive angles and right turns will be negative angles.

Is there a specific part of this that you need help with?

This looks more like you want somebody to help you with your schoolwork.
