Story of Johnny, Hard working atom splitter:

Meet Johnny, who lives by the intersection of lane 2345, and BAG street. Johnny (or little Jon as friends call him) is a hard working family guy. He works at local nuclear power plant in a neighborhood named Sheet3. Due to a recent re-organization at work place, Jon found himself reporting to an almost crazy boss named “Bill Lumbergh”.

Lumbergh asking Johnny to split atoms manully before its too late.. or else...,Now, Lumbergh is not your everyday crazy boss, he is so much more than that. So, one day Lumbergh walks over to Jon’s desk and tells him, “Look Jon, we are having issues in the particle accelerator in the basement. It doesn’t seem to split atoms alright. So I need you to go there and split atoms manually. We got 12,789,000 atoms to be split before next weekend. So I am gonna go ahead and ask you to work on it. Ummkay?

Just when Johnny thought of uttering a curse, Lumbergh came back and reminded, “Oh Johnny, remember to log how much time you are spending splitting atoms. I need you to tell me how many hours you worked for every million atoms. Make sure you follow the latest Timesheet report formats, or else…,

Johnny muttered a couple of real ugly cuss words that are not blog worthy and went about his business of splitting atoms. He managed split only 11 million of them before the deadline given by Lumbergh. Those darned atoms!

Also, Johnny logged the time he spent for every million atoms using, well, excel. Like this:

Data - Start and End times for each task - Calculating working hours between 2 given dates

(Download the data)

Your homework:

Johnny needs your help to figure out how many hours he worked in total (as well as for each million). He is already tired hunting a missing electron in the basement alleys. So don’t tell him to count manually. He wants to have an excel formula that tells him how many hours he worked given a start and end date in cells A1 and A2 respectively. Remember,

  • Johnny never works after 6pm or before 9am
  • Johnny never works on weekends.
  • Lets say Johnny doesnt take any lunch breaks (he has developed a taste for those higgs bosons sandwich with positron milk shake).

So I am gonna go ahead and ask you to complete this homework before the weekend. When you got the correct formula, come back here and post it in comments. Ummkay?

    I prefer the red,grey,light grey,black icon set. I've also used in-cell pie charts from Fabrice's Sparklines for Excel as an alert which could also provide another piece of information.

    For Excel 2007, your formula should do the same as the Excel 2003 version, so that non-alert rows are blank - if they are 0, the unnecessary green icon will show

    Hi Chandoo,

    Nice Post !! just to add something for EXL 2003, we can also 4 Ifs and link to the alert data

    For Ex: If we have alert data in Cell A2 and want to split in 4 orders namely <25%, 25-50%, 50-75% and 75%< then we can following formula and put fonts as you have suggested :

    =IF(A2<0.25,CHAR(153),IF(A2<=0.5,CHAR(155),IF(A2=0.76,CHAR(152)))))

    And then using Conditional Formating we can dashboard reflected on different COLOURS as per their respective alert.

    The Complete formula [Don't Know how it got cut ]

    =IF(A2<0.25,CHAR(153),IF(A2<=0.5,CHAR(155),IF(A2=0.76,CHAR(152)))))

    PS : Use in single line [I have split it to avoid cuts 😉 ]

  6. Rohit1409 says:

    Hi Chandoo..

    why it is not displaying the complete formula..

    anyways here is the balance

    "=IF(A2<0.25,CHAR(153), IF(A2<=0.5,CHAR(155), IF(A2=0.76,CHAR(152)))))"

  7. Chandoo says:

    @Rohit... your formulas are fine. Just that the width of comment area is fixed and hence my website is cropping it at 640pixels. I just edited your formula and added few white spaces so that it wraps nicely.

    Very good idea btw.. kudos!

  8. Tom says:

    Hi,
    Maybe just go for 'bold' ; 'underline' or 'italic' to draw the users attention? Those methods (if those can be called methods) are used cross media type (books, journals, blogs, billboards, ...) to guide the readers eye to valuable information.
    Just a basic thought

    Hi Chandoo,

    You certainly grabbed my attention! although I wasn't sure what my brother (Suresh) and cousin (Shyam) were doing right, and I was doing wrong? 😉

    I love your blog btw - Many thanks for all your hard work in unravelling the secrets and mysteries of Excel!

    I thought I saw an advertisment for a book about learning excel called excel himalaya or something. It cost about 35.00 us money but seemed to have the things I need to have my admin assistant to start to use. I was hoping to start with this book and then send her to school if she shows some interest and aptitude. Any help on this would be appreciated. Thanks

    Great web site and information!!!!

    Hi Chandoo
    Firstly thanks for all the cool tips on how to use Excel better.

    I am new to the site and have a question which you may be able to assist with but dont know if these comment boxes are the best way of asking ?

    I am looking at assets and trying to calculate the depreciation total by taking a year (say 2010) adding the expected life of the asset (say 10 years) then comparing that to a future date (say 2015) using an IF statement. The calculation in normal is - IF((year in col B (2010) plus 10years)>year 2015, add a years depreciation, otherwise leave blank). The converted date value does not appear able to add 10 years in order to compare it to 2015. Am I missing something ?

  17. Rocky says:

    I use the “IF” Statement in conjunction with Conditional Formatting in MS Excel to give verbiage to alert one of a required action, dependant on a review date. This makes a visual stimulus, plus it clues one as to what the conditional format is trying to warn you about and what follow-up actions are required.

  18. Wow, I'm really impressed with dashboards. I had no idea this stuff was even possible with excel. I'd like to offer an interactive dashboard to my customers, showing analytics of their data. I have a .pdf file with the datapoints. I'd like them to enter the data on my website, and be able to see their data. Is something like that possible.

    Hi Chandoo,

    I've recently purchased the package for both templates.

    In the portfolio dashboard,under the calculations worksheet, I'm attempting to change the date range in the gantt chart to show only the range of the project that starts in late 2013.  How do I do this?

    Thanks

    Hi Chandoo,
    I'm new at Excel Dashboard and found your blog really useful and helpful! It's very nice of you that you dedicate your time to do this.
    Could you please explain how can I use Alerts based on dates on a Dashboar?
    For example, if a target date is coming closer to the actual date, the alert is yellow or red.
    I'd really appreciate some help!
    Thank you
