In my Excel workbook, I copy some date information from another (text) source. To be able to do calculations with these dates, I use the function \"DATEVALUE\".
Exam
You can try this formula:
=DATE(RIGHT(A1;4);MATCH(MID(A1;4;3);{"Jan";"Feb";"Mar";"Apr";"May";"Jun";"Jul";"Aug";"Sep";"Oct";"Nov";"Dec"};0);LEFT(A1;2))
Date admits arguments always in the order year, month, day
I admit that day values are always 2 digits.
If you dont mind to write the months abrev. in a range then you can get a much more shorter formula.
Depending on your regional settings you may need to replace field separator ";" by ","
