Google sheet time difference calculation - google-sheets

I want to calculate Total of time difference by creating a funtion in Google Sheet
The format of time Difference is : text(C7-B7,"hh:mm:ss")
Google Sheet
How should I calculate the total of time difference.If I use Add ons it works well but I want to make a custom function which calculates the total of all the difference hours as soon as stop is clicked

If you need to sum, stay away from the text-conversion implied in the formula you shared. Instead try something like:
=MOD(C7-B7, 1)
and set the formatting of the column to 'duration' (if needed).
Then you should be able to sum the differences and obtain the total.
Hope that helps?

Trying to only SUM values in one column based on if the adjacent cells in another column contain a formula

So I'm creating a Google Sheets doc that contains my hours and overtime for an hourly position I have, and how much overtime I'll need to make the amount of money I need to make to survive.
In addition to this I am also trying to track my hours so I can track the actual amount of money I'm making.
So I have a projected clock out time in Column B that uses a formula to tell me what time I need to ideally clock out at based on how many hours I need and what time I clocked in at. When I clock out, I enter the actual time I clocked out at.
In Column C I have the total amount of hours I worked that day, formatted in duration based on the difference between the value in Column A and Column B. If I haven't entered in a value in Column B, it shows me the ideal amount of hours I need that day.
I want to calculate my actual hours worked per week as I'm working that week, so I need to ONLY sum the values in Column C if the adjacent value in Column B is NOT a formula. So I need it to sum the values in column C if I've entered the actual time that I clocked out at in column B.
I've looked up this question and tried multiple solutions I've found here, even tried troubleshooting with ChatGPT, but most are just trying to sum the range that contains the values/formula, and not summing a different column based on if another column has formulas or not.
There seems to be a lot of posts that come super close but don't seem to work for how I need this to work.
Edit: Here is the example sheet.
So F3:F6 are values that have been manually entered, while F:7 has been calculated by a formula.
I need H9 to sum the values of H3:H7, but only the values adjacent to the times in the F column that have been manually entered. In this example, I need it to sum H3:H6 and ignore H7 until I enter a time and remove the formula in F7.
try:
=SUMPRODUCT(MAP(F3:F7,LAMBDA(z,IFNA(FORMULATEXT(z),1))),H3:H7)
You may filter and check if there is a formula with FORMULATEXT. If there isn't it will throw a #N/A error. Then with ISNA it will keep the values in which its adjacents did'nt have a formula:
=SUM(FILTER(C:C,BYROW(B:B,LAMBDA(b,ISNA(FORMULATEXT(o))))))

Sheets record time vs PB time delta

I'm making a spreadsheet to track and compare PB times in a racing game to records in different regions. Trying to figure a way to show a + / - time differential comparing my time to the selected region's record time.
I found a way to make this work in Excel (using the SIGN formula and an if statement to combine the + or - to the calculated difference, required 2 extra columns which had to be hidden which wasnt ideal), but sheets doesn't agree with the format of my data (Tried with it being number, text, time and a custom mm:ss.000 format too).
Is there a way to do this in sheets and preferably a way that just requires the single cell to figure it out?
Thanks!
*Looking to have the time differences shown in the J column, comparing my PB time to the times adjacent times
Here's one solution, but you need to adjust your time format from mm:ss.000 to HH:mm:ss.000 to be able to subtract your time values. Then use TEXT() to convert the results to your desired format
Sample Formula: (Format: +/- s.000)
=if($B$1-$B2>0,"+ ","- ")&text(abs($B$1-$B2),"s.000")
Sample Formula: (Format: +/- mm:ss.000)
=if($B$1-$B2>0,"+ ","- ")&text(abs($B$1-$B2),"mm:ss.000")
Output:

Google sheet Formula for run down total for today's figures

Hie Friends.
What formula can l use to calculate a total for today, then the same formula must detect the change of date tomorrow and start a new and fresh calculation which will be only for tomorrow. the next day it will repeat the same process by itself, automatically without being manually dragged down. lam looking for running total for Total Deposited, in Column "J". Currently lam using the formula: =sum($D$2:D5) for cell "J5".Thank you.
You will need to use SUMIF
If I have understood your setup properly it would need to be =SUMIF(A:A,TODAY(),D:D) although without seeing the full sheet with columns unhidden you may need to adjust the above to suit your requirments.
use in J2:
=ARRAYFORMULA(IF(E2:E, MMULT(TRANSPOSE((ROW(A2:A)<=
TRANSPOSE(ROW(A2:A)))*E2:E), SIGN(E2:E)), IFERROR(1/0)))

Google Spreadsheets Repeat Function Nth Times & Sum Results

I have the following function
=IF(RAND()<0.25,1,0)
RAND() returns any value between 0 to 1 in decimal format and the idea is that an item has a 25% chance of getting a 1. If it was less than 0.25 the rand() then its a hit and gets a 1 otherwise a 0. Now lets say I need to do this 100 times and add up the sum of all the '1's that were created, which in this case will average to around 25 for 25%. How do I do this in Google Spreadsheets?
Basically looking for a way to repeat a function n'th amount of times and sum the results.
I have looked around everywhere (youtube, google forums) and have not found any solutions.
I may as well put this as an answer because it tries to address the broader question of whether you can repeat a function (say) 100 times. The answer is, yes if the function is compatible with an array formula. Rand can't be used in this way because it doesn't take any arguments (neither do some other functions like countifs for some reason). But you could get round it by using Randbetween instead and providing it with 100 array elements. These are multiplied by zero so don't actually affect the answer, but Google Sheets still evaluates the function 100 times:
ArrayFormula(sum(if(randbetween(0,A1:A100*0+99)<25,1,0)))
or
=Sumproduct(if(randbetween(0,A1:A100*0+99)<25,1,0))
The result is each time you force this to re-calculate (by changing something in the range A1:A100 or by setting File -> Spreadsheet Settings -> (Tab) Calculation -> Recalculation to every minute) it will give an answer around 25.
To make it more resilient (allow any value in A1:A100 including error values) could try
=ArrayFormula(sum(if(randbetween(0,iferror(A1:A100/0,0)+99)<25,1,0)))
or
=Sumproduct(if(randbetween(0,iferror(A1:A100/0,0)+99)<25,1,0))
I don't know why I didn't do this in the first place
=ArrayFormula(sum(if(randbetween(0,row(A1:A100)*0+99)<25,1,0)))
then this easily allows for a variable range
=ArrayFormula(sum(if(randbetween(0,row(indirect("A1:A"&H1))*0+99)<25,1,0)))
where the number in H1 doesn't have to be limited to the number of rows in the sheet.
Okay so I found a very convoluted answer. If someone finds a better please let me know.
The first thing as the user |'-'| commented was to create a range on separate sheet.
Since I know that I will not be looking up more than 200 values at once I created my range to be 200 long of this formula.
=IF(RAND()<0.25,1,0)
This will create the initial list of random values.
The next step is you need to generate a randomizer seed. Which is basically a random number between the range you created. You can do this with
=RANDBETWEEN(1,200)
This should be on the same column as what you are trying to sum up later.
Next you want to create a dynamic string that you can access via arrayFormula later.
="Randomizer!B"&B12&":B"&B12+B3
In my case I had the 200 random numbers on a sheet called randomizer. Notice the &, this is how you connect strings. In my example B12 is the reference to the =RANDBETWEEN(1,200), and B3 is how many times I want the randomness to occur. It can be any value as long as it's less than the randomizer seed by the amount of times you want it to be random.
Finally refer to this string using, =SUM(ARRAYFORMULA(INDIRECT(B13))) , indirect lets you refer to a string as a cell and this is how I was able to create a dynamic range to calculate from.
I will say the advantage of this method is its super fast to calculate since the random numbers have been pre-computed.
The idea is that it will keep creating random ranges from the precomputed random numbers you created, and then summing those ranges, essentially calculating random numbers n'th amount of times.
Hope this helps someone.

Google Sheets: Add value to total if a row condition matches for infinite column

I am attempting to make a Google Sheet that has a column for a rate and a value of that rate. Each night I am adding a new value to the bottom of this list so I want it to continue as an infinite list. What this sheet should do is look down the list of rates, if the rate matches a predefined rate, it should add the corresponding value to the total for that rate. I have four common rates that occur in no particular order and with some given value. I would like to total the values for each of those rates and give them in the totals section so each rate can be easily referenced.
Is there a way to do this using Google Sheets built-in commands? Pseudocode would be something like IF(A2:A = rate, add value in B to total). I know to make an infinite reading of a column by A2:A, but I don't know how to check each value as it goes through that column. I have attached a test spreadsheet with some sample values and the output that should be given by the formula. Thank you in advance for your help.

I managed to discover my own answer using the SUMIF statement. My code for the rate of .75 is ""=SUMIF(A2:A,"=.75",B2:B)"". I ran into some more trouble with the section for a different rate because I was having trouble saying not equal to .75 or 1 or 1.5 or 1.75. I solved this problem by completely bypassing it and adding the all the values and subtracting away the values already added. I would still like to know how to give the list of "ors" if someone could shed some light on this. But I now have a working solution regardless. I have updated the test sheet to show the solution.
