I’m doing a report which calculates people’s time to determine their pay. We pull reports from our servers and paste them into Excel to do the calculations. I have run into an issue when pulling the data: if the time they logged in for was less than an hour our formula is not working:
=IF(E159="","",((HOUR(E159)+(MINUTE(E159)+(SECOND(E159)/60))/60)))
This gives an error (#value) if the time is :34:15, but if it’s 00:34:15 then it’s fine.
Formatting the cell does not appear to work.
I’d like to go through this column and add the 00 to all values missing it, and I need some help or guidance from there.
Another question on SO looks like it may help, but I’m unsure on how to use it.
Assuming that The tiem is in cell E159 from your above formula, you can append a 0 to the start of the time. This will fix all the times that have the hour missing and won’t affect the other lines.
You can then replace all of the
E159references in your original formula with this edit so that it looks like this:While it’s hard to read, it does the trick.
While that answers you question.. I think that there is a better way to achieve this formula.
It looks like the end result you’re looking for is the time converted to hours, with mulutes and seconds as a decimel to the next hour. You can achieve this by doing:
Which will give you the same result as your original formula.
And then to combine that with my first answer to get a formula that looks like:
This approach is much easier to read / edit and provides the same output.
Why This Works
Excel stores all dates as whole numbers, and all times as a decimel % to a day.
So when Excel is stores 12 hours it saves it as .5 because it is half of a day.
By dividing the time output by 24 we are converting the entire time value down from a % of day to a % of hours.
