I have a spreadsheet sent to me and it has a column of dates in the following
format - mm/dd/yy
I would like to change them to yyyy/dd/mm but I can't seem to change
existing format. Any ideas on how this is done?

Maybe they aren't real Excel dates, but text. You can check with the ISTEXT() function.
If they a

=DATE(RIGHT(A1,2)+2000,LEFT(A1,2),MID(A1,4,2))
and format as required

Niek,thanks for the reply, but I am unsure of what you mean (not an expert on
excel at all)...can you clarify?...thanks

Assume your date is in A1. In B1, enter this formula:

=ISTEXT(A1)
If you get TRUE as a result, than your date is no real Excel dat, but is text.
In that case, enter the formula I suggested.
In both cases, FormatCellsNumber tab, choose Date, and choose a format from the list that suits your needs.

If no such format is in the list:

FormatCellsNumber tab, choose Custom. In the Type box, enter "yyyy/dd/mm" (without the quotes)

BTW, what do you see if you format the cell as General?

Just because data looks like dates, doesn't make them dates.

If you tried changing the format and the display didn't change, then Niek was
guessing that your data isn't really a date. (A real date would show the change
in format.)

Niek suggested putting a formula into another column and creating the date that
way from the cell with the "text date".

Another way is to select that column of dates and do
Data|Text to columns
fixed width
Don't add any lines and remove any that excel added
choose mdy as the date format.

This will convert that selection to real dates.

Now you should be able to format those cells the way you want.

Dave/Nick....many thanks for you tips. I went with the Data/Text to Columns
option and it worked a treat.
