not so much formatting as a complete rejig of the data in the cell
1st you must understand that dates / times are simply numbers FORMATTED to look like a date
The Number associated with a date is the number of days that date is from 1/1/1900
Excel can interpret many things as dates but in order to do so, it must either LOOK like a date or be able to be formatted as a date. Thus, you must split your number up to make it LOOK like date. Excel can then evaluate that and convert it to a true date:
To split the number:
=left(A1,2)&"/"&mid(A1,3,2)&"/"&right(A1,2)
To evaluate that split:
=VALUE(left(A1,2)&"/"&mid(A1,3,2)&"/"&right(A1,2))
Once you format that as dd/mm/yy, you will get the result you want. This all assumes that your 231104 is in cell A1
