Hello,
If you have correct dates and not text - you always can sort them, since date and time are stored as integers + a fraction of a day (=decimal numbers). Thus sorting real dates and times reduces to sorting decimal numbers, regardless of the format.
If your dates don’t correctly sort, you don’t have dates but text (which is probably your real issue). Select the column and change the format to “Number” and Format Code 0.00000000
(Decimal places 8, Leading zeroes 1). If you now find entries which do not turn to a decimal number, then these are text and no real dates (Revert the format back).
If text is your real issue, then
- Select the column with you textual dates
- Go to
Data -> Text To Column
- Select from Column type the correct date format your “textual dates” appear
- Click button
OK
- Perform “Decimal number format”- check from above again
Hope that helps.
