applying str_split_fixed function simultaneously across multiple columns in r

I have a data frame which is having multiple columns each column is having string values. I want to split column values by coma separator in the output data frame. Input and required output are as below

Col1=c("a,b,c","9,a,5")
Col2=c("c,b,e","4,r,t")
Col3=c("e,f,g","y,z,d")
Input=data.frame(Col1,Col2,Col3)

Column1=c("a","9")
Column2=c("b","a")
Column3=c("c","5")
Column4=c("c","4")
Column5=c("b","r")
Column6=c("e","t")
Column7=c("e","y")
Column8=c("f","z")
Column9=c("g","d")
Output=data.frame(Column1,Column2,Column3,Column4,Column5,Column6,Column7,Column8,Column9)

If anyone know the solution please help.

>Solution :

The package splitstackshape is made for such operations,

library(splitstackshape)

cSplit(Input, names(Input), type.convert = 'as.is')

#   Col1_1 Col1_2 Col1_3 Col2_1 Col2_2 Col2_3 Col3_1 Col3_2 Col3_3
#1:      a      b      c      c      b      e      e      f      g
#2:      9      a      5      4      r      t      y      z      d
