Converting normal time to Epoch time format using excel

[Colombo]

I'm working on converting some databases. One has entries with normal human readable time format, the other uses the unix epoch time format.

Is there a function or vba code that I can use in excel to convert the normal time format to epoch time?

I've got a thousand or so entries, so it would be nice to find a way to do this on a large scale.

Thanks

Josh

If you put that formula in B1 then you should be able to "drag" it down. Put the formula in cell and then place the cursor on the bottom right of the cell until you see a black "+" - that's the "fill-handle".

Then you can do one of two things, either hold down the left mouse and drag down as far as you need or you can just double-click left mouse and the formula should automatically fill down as far as you have continuous data in an adjacent column.

Thank you so much that is very helpful. I did not know you could auto fill the columns with a double click, that will help me heaps.

How can I make this a format cell button or macro?
Where I would not need to remember this formula?
Or add an additional column?

I would like to convert: epoch time to dddd, mmmm dd, yyyy hh:mm:ss

Thank you
