Hi,

There are several on-line convertors - if you do a serach for “quaternion converter”.
You need to check the results as the order of the Euler angle input on some is not the same as the 'ABB" way (you just need to swap the order you enter the angles to get it right).

Hope this helps

Hi Graeme,

Thanks for your support.
It is ok to find the convertor online. but it will be better if there is some VBA in Excel, we could utilise it whenever we want.
