Convert milliseconds to date (in Excel)

[ForumBot]

I have a row in excel with the following data: 1271664970687 (I think it's the number of milliseconds from 1970...).
I would like to have addition row that will show it as date/time.

Converting your value in milliseconds to days is simply `(MsValue / 86,400,000)`

We can get 1/1/1970 as numeric value by DATE(1970,1,1)

```
= (MsValueCellReference / 86400000) + DATE(1970,1,1)

```

Using your value of 1271664970687 and formatting it as `dd/mm/yyyy hh:mm:ss` gives me a date and time of 19/04/2010 08:16:11
