Hi Experts,

I download a CSV file and when I open the file I see the dates as serial numbers(10 digits).
I tried to change the format cells to date but still doesn't work.

Please advise

I found this to convert Excel serial date to regular date format.

=UPPER(TEXT(A1,"mmm-d"))

Open in new window


You can probably mes around with the "mmm-d" part to get the exact format you want.

Without any other information it is hard to guess how the dates have been converted to numbers, and hence how to convert them back again,

Today's date (10/2/2014) has the value of 41680 in Excel.

Can you give some examples of the 10 digit numbers, and the dates that they represent?

When you say 10-Digit time, I believe you are talking about unix time.

try use the following formula to convert the timestamp.

Put the 10-Digit date in A1, then the formula in another cell.

=A1/(60*60*24)+"1/1/1970"

After that, format the formulated cell to Date format in excel.
