Hi,

I have a dataset and I have to remove everything affter '_'

name	last name	code
abc	def	MQ_ALs_234589
KJF	KLJ	ERT_Alte_kjm56
FGH	LKJH	#3_LKJ
MKJH	KL	456_KL_MKL_KL

Output:

name	last name	code
abc	def	MQ
KJF	KLJ	ERT
FGH	LKJH	#3
MKJH	KL	456

@Sshasnk This can be done with the help of the substring function
