Most of you know that during day time I work as a business analyst. Today while preparing some test scenarios for our latest insurance application, I came across a weird problem.
There are some steps in testing. For each test scenario, a combination of these steps is required. It is my responsibility to identify the steps as well as their combinations for each of the scenarios. So I quickly prepared a table with all the steps in left most column and one scenario each in one column. I put “X” in a cell if the step needs to appear in that scenario. But when I gave it to our testing team, they asked me if the scenarios can be explained a little better. See this picture to understand what they want and what I made.
So I immediately converted the “X”s to actual step names using a simple IF formula. (Copied the table, and wrote ‘if there is an X in the previous table, get the actual step from left most column otherwise empty‘).
Then the problem of actually removing various blank cells. First I tried to select all the blank cells and remove them using our technique from last week. But it failed as the blank cells are actually formulas with empty values. So I copy pasted the entire table as values (CTRL+C, ALT+ESV). But even then excel wont recognize blanks as true blanks (because the value is actually “” instead of being plain empty.)
Now I didnt want to manually select all the blank cells as the real testing scenario table had 50 scenarios with 68 possible steps.
Then it stuck me, why not use FIND (CTRL+F) to find all the cells containing nothing? So I selected the scenario table, opened the find and looked up all the cells that contain empty values. Now I clicked on “Find all” and selected the entire list of values from that. Finally I removed all these cells and bingo!
PS: Our testers was more than happy as it took very little time and they had all the scripts ready.
PPS: Thanks to Rick, who taught me FIND ALL approach to select blank cells (here).

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
