So I'm trying to build a spreadsheet to keep track of my working hours. But to make it more "automated" I need additional features. One of them is being able to treat specific strings as numbers, and use them in a formula.
Lets say that I'm John in the following example. I have 160 hours in paid vacation left, and I have manage to build pretty large chunk of paid flex time. Normal working hours is between 8-17. If I come in at work at 7 and leave at 17, I get +1 flex hour.
If I want to use my flextime I can in this case type -8. And the formula in I5 would be =SUM(C4:G4) to sum this week/month/year what ever. And the final result, this weeks usage subtracted with the total (J5) =B6+I5.
But, what if I want to use my vacation time? In this example I want VT to be equal to -8 hours as well, but subtracted from the vacation time total. Im using Excel version 16.27 on MacOs.
The formula is : =COUNTIF(C4:G4,"VT")*8
I4 = =COUNTIF(C4:G4,"VT")*-8
I5 = =SUM(C4:G4)
J4 = =B5+I4
J5 = =B6+I5

so I am a complete excel and math noob and I want to have a cell in excel which will display the "Pelayo number", which is used in calculating bias in a roulette wheel. You can read more about it here: https://www.roulette-bet.com/2015/06/the-roulette-bias-winning-method.html
enter image description here
Let me explain briefly what I want. As you can see on the image there are two columns, in one there are the numbers on a roulette wheel and and in the second one there is the frequency of each number. On top you see number of spins (852). The number on the bottom (23,02.....) is the expected frequency of each number. The table is dynamic, constantly evolving as I enter new data.
Now I want a cell to display the total number of positives. Which is calculated like this:
If there have been 300 spins, each numbers has to have been spun 300/36 = 8.33 in order to be breaking even. This means those which have been spun 8 times are losing a little, and those which have showed 9 times are winning something. If a number has appeared 14 times it is clear it has 14-8.33 = 5.67 which we will express in an abbreviated form like +5. Let’s suppose the exact same situation has occurred for 6 other numbers also, they all will make a total sum of 5.67 + 5.67 + 5.67 + 5.67 + 5.67 + 5.67+ 5.67 = 39.69. as no other number has been spun over 9 times, then we say the amount of total positives at this table at 300 spins is +39.
TLDR So ideally something like: Select all the numbers from (G6:G42) which are bigger than value in (G50) and then substract them one after another from the expected frequency (G50) and then add this all up.
I tried to solve it but just couldnt find a tutorial anywhere
I'll break this down for you, and show you a few helpful Excel concepts along the way.
Especially if you are a beginner, I'd recommend using a helper column. Helper columns are great ways to break down complicated functions into smaller, more manageable parts.
In H6, write =IF(G6>G$50,G6,0). That if statement will set us up for our sum, with either the value in G6 or a 0. The $ will be cleared up in a moment.
Then, hover your mouse over that cell, and a little square box will appear in the lower right corner of H6. Grab that tiny box, and drag it down to H42. This fills in the formula, adjusting all of the numbers relatively as you go. Note that the 50 stayed constant, however - that's what the $ did!
H6 is now your helper column. It doesn't find your answer, but it gets an important, intermediary step done.
Finally, wherever you'd like your answer, write =SUM(G6:G42), and you should be well on your way.
=SUMIF(G6:G42,">"&G50,G6:G42)-COUNTIF(G6:G42,">"&G50)*G50
It sums values that are over in G50 then distracts G50 value as much times as there were values to sum up to.
For example in case G50 is 23.02 and you have values 20, 21, 22, 23, 24, 25.
It would calculate like (22+23+24+25)-4*23.02
I have a spreadsheet which has employee working times, listed as Sat-In and Sat-Out for a specific date. The employee shift spans several ours and each "In-Out" period is recorded as a separate line which means the time between the Sat-Out and the next Sat-In means the employee is on a break. I also calculate the time, in minutes of each "sitting" period.
What I can't seem to figure out is how to add a formula which takes the data and further refines it in this manner:
1. I have a core period of 1030-1530, as an example, which is the busy time and requires the maximum employee coverage. The shifts of employees generally spans this core, but in some cases their shift may start or end in the core.
2. I want to calculate how many minutes the employee worked within the core only. I can obviously do this manually using the data, but a formula would be preferred, if possible.
3. As an example, if a person sat-in at 1445 and sat-out at 1545, the core time calculation would be 45 minutes (1445-1530).
I've attached a snapshot of the data to help my explanation.
FYI - the information is pulled from a database as JSON data and converted to excel. I'm not very familiar with JavaScript, but if someone knows a way to do it programatically, I'm willing to give it a try and learn.
Thanks!

In below example I've used: =MAX(0,MIN($O$2,H2)-MAX($O$1,G2)), and formatted like [mm].
In Excel, units are days, so if you want to calculate the amount of minutes between two timestamps, you need to subtract both and multiply the differencee by 24*60 (being the amount of minutes in one day).
E.g. You start working at 09:07 (cell B2), and finish at 18:07 (cell B3), having a 45-minutes break. Then the time you worked in minutes, is:
=(B3-B2)*24*60-45
Make sure the cell formatting is correct (general), you'll get : 495.
I'm trying to figure out a way to create an excel spreadsheet that will allow me to keep track of how many hours I've earned per each paid holiday my company offers, then keep track of how many hours I've used and what's remaining. But I'm unsure how to calculate this properly.
I could easily do the math my self as it's a simple lay out, but I'm trying to find a way that will just let me enter the numbers for earned and used and walk away from anything else.
What I'm trying to do is the follow:
Have multiple sections. In the first section it'll be my holidays. So in like Column A, working down I'd have New Years, Memorial Day, July 4th, etc. Column B working down would be time earned. But this would be labeled in each cell as "8 Hrs" or "4 hrs". Column C would be time used in the same format "4 hrs" "8 hrs". Then Column D would simple be hours remaining.
Now in the second section I'd have holiday hours earned, which is 2 weeks. Not too sure how to lay it out, and then I still have my sick days, but not sure if I should include that in section 2 or not with the vacation time.
I'd like a way to be able to simply Calculate B2 - C2 = D2. So 8 Hrs - 4 Hrs = 4 Hrs (to show 4 Hrs remaining for each line item.)
Problem is I'm unsure how to calculate remaining time simply because of the Hrs suffix. And with that I also can't calculate total time still remaining, both for holiday hours earn and vacation/sick hours.
Yes, it's easier for me to track it as 8 Hrs rather than 1 day, etc.
Any advice on how to formulate this. Or if anyone knows of a premade template that fits this type of scenario, that I could then just take and integrate into my own spreadsheet.
Sorry if this is confusing in any way.
Also, As I'm no excel wizard, unsure if this is relevant or not, but I'm using Excel 2016, as part of the Office suite.
Another option is to just leave the number as it is and label the column accordingly. Do you really need to see "hrs" in every cell when you know you are tracking hours?
Use a custom number format of,
[>1]0 \H\r\s;[=1]0 \H\r_);0 \H\r\s;[Red]#
... and treat all hours as integers.
In an Excel 2003 spreadsheet, I have the top row of cells calculating the number of days and hours I have worked on something based on data I put in the cells below for each category. For example I enter the time spent on Programming, Spoken languages, house, piano, guitar...etc. The top cell in each category will keep track of and display how many days and hours I spent as I add the time spent for each category each day. I want to evaluate this top row and then list in a "report" (like a pop up box or another tab or something) in order from least amount of time to the most amount of time. This is so I can see at a glance which category is falling behind and what I need to work on. Can this be done in Excel? VBA? Or do I have to write a program from scratch in C# or Java? Thanks!

Unbelievable... I've been scolded for trying to understand an answer and requested to mark this question answered. I don't see anything to do this and could not find anything that tells you how, so I'm just writing it here. MY QUESTION WAS ANSWERED... But thanks anyway...
Consider the following screenshot:
The chart data is built with formulas in columns H3:I3 and below. The formulas are
H3 =INDEX($B$3:$F$3,MATCH(SMALL($B$2:$F$2,ROW(A1)),$B$2:$F$2,0))
I3 =INDEX($B$2:$F$2,MATCH(SMALL($B$2:$F$2,ROW(A1)),$B$2:$F$2,0))
Copy down and build a horizontal bar chart from the data. If you want to change the order of the source data, use LARGE() instead of SMALL().
Alternative Approach
Instead of recording your data in a matrix, consider recording in a flat table with columns for date, category and time spent. That data can then easily be evaluated in many possible ways without using any formulas at all. The screenshot below shows a pivot table and chart where the data is sorted by time spent.
Edit after inspecting file:
Swap rows 2 and 3. Then you can choose one of the approaches outlined above.
Consider entering the study time as time values. It is not immediately clear if your entry 2.23 means 2 hrs and 23 minutes, or 2 hrs plus 0.23 of an hour, which totals to 2hrs, 13 minutes.
If you are using the first method, then all your sums involving decimals are off. For example, the total for column B is 7.73 as you sum it. Is that meant to be 7 hrs and 73 minutes? That would really be 8 hrs and 13 minutes, no? Or is it meant to be 7 hrs and 43 minutes? You can see how this is confusing. Use the colon to separate hrs and minutes and - hey - you can see human readable time values and don't have to convert minute values into decimals.
Where I work I don't get paid overtime, but I accrue holiday days for the overtime I work. I have the following spreadsheet which calculates how much overtime I've done and totals it in D15.
Now I want to calculate how many days this is, based on 8 hours per day. In D16, I've done =D15/8 and formatted it as h.mm \d\a\y\s, but this shows as 2.26 days instead of 2.4375 days.
What is the correct formula to use in D16?
Note to reader: this question led to multiple solutions some of which were discussed in the comments. Here is a summary of the solution found.
First solution
=(HOUR(D15)+MINUTE(D15)/60)/8
Explanation
Dates and time in Excel are stored as serial numbers, so 19:30 is actually 0.8125.
So, if you divide it by 8, you will get 0.1015625.
This latter value is worth 2.26 days
OP's version (thanks to Danny Becket (OP)) - see the comments below.
This solution now handles hours > 24.
=((DAY(D20)*24)+HOUR(D20)+(MINUTE(D20)/60))/8
or better (credits to Barry Houdini):
=((INT(D20)*24)+HOUR(D20)+(MINUTE(D20)/60))/8
The former formula has a limitation for large values, perhaps not relevant here but if D20 is 800:00 then you get the wrong answer (7 days rather than 100 days). This is probably because DAY function is giving you calendar day which will "reset" at 31, best to use INT in place of DAY.
Another easily understandable version
Divide by the length of the day as a time value:
=D15/"8:00"
More easily changed if length of workday changes
Enter:
in B3 8:3
in C3 16:3
in D3 =IF(B3<C3,C3-B3-1/3,2/3-B3+C3)
Select B3:D3, format as hh:mm and copy down as far as required.
Sum ColumnD and append *3 to the formula, but format as Number.
Add data by overwriting cells in ColumnB and/or ColumnC as required (defaults do not add to total).
Copes with overtime up to next regular start time (ie including past midnight, new serial number). 1/3 because standard working day is 8 hours (24 hours is unity for date serial counter). B3 and C3 could be hard coded but (i) there is no need and (ii) allows more flexibility. If to readily identify non standard start/finish could use conditional formatting.
Does not address weekend overtime but could easily be adapted to do so (eg add column, flag weekend day with 8 in that extra column then add that 8 [1/3] to the finish time).
Make sure that D15 has a number format of [h]:mm
then have D16 as =sum(D15/"8:00") should work fine
thats what i have tracking my annual leave, I work 37h pw with a leave day being classed as 7h24m or a half day of leave as "3:42"
I have leave taken as a cumulative figure assigned as [h]:mm in cell K2 of my spreadsheet
then I have K3=SUM(K2/"7:24") for days taken formatted as a general number
you may also need to change the date datum in excel to the 1904 date system http://support.microsoft.com/kb/182247/en-gb
to get this to work (only a problem if you have negative time as I do when calculating flex hours)
