I have excel file a date column, some of date are align to the right while others to the left.when i read the into r am getting this error.
Expecting date in A3547 / R3547C1: got '13/04/2018'
on dates align to the left. I have tried to clean the date in excel with no success,
You can do something similar to this
Formulas are as below
B2: =FIND("/",A2)
C2: =FIND("/",A2,1+FIND("/",A2))
D2: =LEFT(A2,B2-1)
E2: =MID(A2,B2+1,C2-B2-1)
F2: =RIGHT(A2,4)
G2: =DATE(F2,E2,D2)
Depending upon your actual data you may need to amend the formulas a little bit.
