Urgent help in AD

Hey guys, i am new to AD, and i currently face some problem.

i had a domain with many users and groups, and right now, i want to export them out to an excel file in such format

group 1 : member 1
group 1 : member 2
group 1 : member 3
group 2 : member 1
group 2 : member 3
group 3 : member 1
.
.
.
.

But not matter how i try,  i cant seem to get both different object (users and group) together. sometimes even get back the word length only....

So guys, can y'all kindly help me to solve this problem?
