Hello forum! After probably 10 hours searching on google and youtube for help i found this forum.
I'm a teacher and i have a presentation in 2 days. I have this issue that i cant solve. Basically i'm trying to separate the school students 3 in 3. I have a list of 4000 students and i want to separate the students 3 in 3 so i can print like that.

The list is like this. Example:

a
s


f
f
h
d
s
f
d
f
t
f
s
f
g
d
f
g
f
etc.............

i want to separate automatically in WORD 2016 to 3 in 3. To look like this :

d
i
f

y
g
e

y
j
v

u
f
n

etc....


I know this is probably the most stupid question someone done here and i'm sorry for that. I'm not a tech expert. I'm 56 years old. Thank you for your help and have a nice day!
