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?

    Hi Chandoo,

    your recent postings include only Excel 2007 templates. Unfortunately the company I work at still runs Excel 2003. Is it possible to get your awesome files in other excel version as well?

    Thanks so much for your great excel stuff!

    Is it possible to do this for shifts with hours instead of days? To organise a three shift day?

    Thanks in advance,

    Stelios

  3. MASTHAN says:

    In my organization there are 45 employees i need split then into three shifts ex:A shift:14,B shift:14,C shift:14 and week off:3 kindly help me on this.

  4. Hui... says:

    @Masthan

    You need to understand what rules your company has for the various shifts / roster combinations

  5. Georges Lacombe says:

    Chandoo, I once did a shift control spreadsheet for my team. I put one person in each line, the columns were the days. I put a shift code in each cell indicating in which shift that person should work, or if the person were out that day. I have two codes for being out. One is for vacations and one is to compensate days worked in weekends. This way I was able to count how many persons I have in each shift, how many were on vacations and how many were out compensating (that's the term we use here) weekend worked hours.
    Later I included the possibility of a person be in two lines one for normal hours other for overtime. This is mainly used for planning purposes. If you would like I can send you an example. The only problem of this spreadsheet is that we don't have a person view, only this consolidated view.

    • Chuck Vaughan says:

      Hi George, I would like to have a copy of your spreadsheet if you can share it.
       
      Thanks in advance, Chuck   

  6. Idan says:

    Hi Chandoo,

    Where is the code located ? is it VBA ? If so , how do you hide it ? Or it is .NET ?

    Thx

  7. Hui... says:

    @Idan
    .
    No VBA or code, it is all done with Mirrors.
    Only Joking,
    .
    But there is no VBA or code,
    It is all done with Named Formulas and Lookups.
    Have alook at the cells in the calander area and Named Formulas in the Formulas, Name Manager Tab.

  8. Anand Sant says:

    How can i calculate between two or more different workbooks? Please, reply me as early as possible.

    • Hui... says:

      @Anand
      Open the workbooks you want to link to
      Start a formula = and click and change between workbooks as required.
      You can use the View, Switch window menu to change workbooks mid formula

      The format for using workbooks is
      =[Workbook.xlsm]Sheet1!$A$1
      or
      =SUM('[Book2.xls]Sheet1'!$A$1:$D$10)
      etc

And every each group must work on sunday to take turns. In fact we are security teams so that's why sunday is required to work. Pls guide and show how to put in the working calendar. Thank you in advance.

  15. Veronica Burggren says:

    I've been trying to copy and/or recreate this to use in a workbook I'm doing for the transportation department I'm working for. I need to have the calendar on the first sheet in my document (it has graph's from data on another sheet). I'm trying to use it to track (with the conditional formatting) accidents and injuries. I've redone the conditional formatting to do 4 different accident types (no injury, near miss, OSHA recordable injury and work loss injury), but when I enter the formula's you have in the calendar portion where it says "DateOfFirst-FirstWeekDay" I can't figure out how you did that. Are you able to help?

  16. Pipin Fantom says:

    I would like to use Excel to solve the following problem for a community work. I want to create a Driver schedule for a given month from a pool of volunteers for a community service. Each of these volunteers can drive only on specific days in a week. I would like to populate the driving schedule for each weekday with primary, secondary and tertiary drivers in a random fashion so that I do not overburden one person. I would greatly any help you can provide.

    solution 1:
    mydata=B2:C16
    stoplist=E2:E8

    =LET(RNG,A2:A16,SMR,C2:C16, F,(RNG=E2)+(RNG=E3)+(RNG=E4)+(RNG=E5)+(RNG=E6)+(RNG=E7)+(RNG=E8),SUM(SMR)-SUM(SMR*F))

    =LET(RNG,A2:A16,SMR,C2:C16,RH,N(B2:B16=B2), F,(RNG=E2)+(RNG=E3)+(RNG=E4)+(RNG=E5)+(RNG=E6)+(RNG=E7)+(RNG=E8),TOT,SUM(SMR)-SUM(SMR*RH*F),SUM(SMR*RH)-SUM(SMR* RH*F))

    ALTERNATE SOLUTION
    =SUM(C2:C16)-SUM(FILTER(C2:C16,ISNUMBER(BYROW(A2:A16,LAMBDA(a,TOROW(SEARCH(a,E2:E8),2))))))

    =SUM((B2:B16=B2)*(C2:C16))-SUM((ISNUMBER(BYROW(A2:A16,LAMBDA(a,TOROW(SEARCH(a,E2:E8),2))))*(B2:B16=B2)*(C2:C16)))
