Recently I was going through a set of data in excel which had dates in dd.mm.yy format e.g. 03.06.12
The dates did not allow to do any calculation on them as they were imported as text format.
Doing find and replace “.” With “/” with Ctrl+H command didn’t help as it changes the date format to mm.dd.yy with dates as months and vice versa, in some cases dates greater than 12 produced error.
I used the formula
RIGHT(),MID() and LEFT() extracts the dates year, month and date value
100 is added to RIGHT() as year belong to 2000’s
DATE() put them in order
Now I was able to format and do calculations on dates
