If your Unix time is in cell A1, then =A1/(24*60*60) + DATE(1970,1,1) should
convert it; you'll have to apply a Date/Time format to the result.

(BTW the division by 24*60*60 is because '1' represents a day in Excel.
Also, I've interpreted your post to mean that Unix time started at 12:00:00am
on 1/1/70).

Are there any Excel functions available to convert Unix time (seconds since
1/1/1970) to a readable date/tiem? Or does anyone know of a calculation I
can do to convert this type of data to a date/time that is more usable?

I can find converters on the web, but I need a function or macros within
excel.

Thanks
