Excel Date Conversion from yyyymmdd to mm/dd/yyyy

I have been searching for about an hour on how to do this in Excel.

I have an Excel file that was created from an old system and I am pulling information from a SQL Server Database, I will be inputting the information back into the SQL Server Database and would like the Dates to match.

I have tried Creating a Custom Format, but I am unsure if I even did it Correctly. I found several places where they want to go the other way mm/dd/yyyy to yyyymmdd but they have not been helpful.

I am unfamiliar with using VBA in any Microsoft Products otherwise I am sure that this would be a simple Task.

I have two separate columns that need to be changed.

How do I Format the entire column from (float)yyyymmdd to a (Date)mm/dd/yyyy

You can convert the value to a date using a formula like this, next to the cell:

=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2))

Where A1 is the field you need to convert.

Alternatively, you could use this code in VBA:

Sub ConvertYYYYMMDDToDate()
   Dim c As Range
   For Each c In Selection.Cells
       c.Value = DateSerial(Left(c.Value, 4), Mid(c.Value, 5, 2), Right(c.Value, 2))
       'Following line added only to enforce the format.
       c.NumberFormat = "mm/dd/yyyy"
   Next
End Sub

Just highlight any cells you want fixed and run the code.

Note as RJohnson mentioned in the comments, this code will error if one of your selected cells is empty. You can add a condition on c.value to skip the update if it is blank.

Do you have ROWS of data (horizontal) as you stated or COLUMNS (vertical)?

If it's the latter you can use "Text to columns" functionality to convert a whole column "in situ" - to do that:

Select column > Data > Text to columns > Next > Next > Choose "Date" under "column data format" and "YMD" from dropdown > Finish

....otherwise you can convert with a formula by using

=TEXT(A1,"0000-00-00")+0

and format in required date format

Here is a bare bones version:

Let's say that you have a date in Cell A1 in the format you described. For example: 19760210.

Then this formula will give you the date you want:

=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2)).

On my system (Excel 2010) it works with strings or floats.

for converting dd/mm/yyyy to mm/dd/yyyy

=DATE(RIGHT(a1,4),MID(a1,4,2),LEFT(a1,2))

Found another (manual) answer which worked well for me

1. Select the column.
2. Choose Data tab
3. Text to Columns - opens new box
4. (choose Delimited), Next
5. (uncheck all boxes, use "none" for text qualifier), Next
6. use the ymd option from the Date dropdown.
7. Click Finish
