Excel formatting seconds and minutes/time? - excel

I have values displayed as 29.87, which is 29.87 seconds in from my POV, Sometimes I have minutes entered as 1:09.89, meaning 1 minute, 9 seconds, etc.
My main question is can I work a formula to add something like 29.87 with 40.02 so it displays as 1:09.89 after adding the two numbers from the cells? Currently, it displays as 69.89 when added, and no other display option I have tried have it correctly displayed how I want it to be.

Use this formula : =TEXT((A1+B1)/(24*60*60),"HH:mm.00")

Time Study in Excel

I am completing a time study and recording time in excel. I have numbers like 2.24, etc.. I am trying to add them and average them and I am getting numbers like 9.76 when I really want 10m and 16seconds. Any thoughts to fixing this?
When I change the format to mm:ss it give me wild answers
If 9.76 is a decimal number and it's is in A1, then in B1 you can use:
=((A1-(ROUNDOWN(A1;0)))/0,6+(ROUNDOWN(A1;0)))/24
Also, format of cell with formula must be hours (I've used [hh]:mm:ss)
Applying this, I get:
I've done it in the following way: I used cell formatting, like u:mm:ss (in English locale, this might be h:mm:ss instead).
In one cell, I've put 0:2:24 (zero hours, two minutes, 24 seconds).
In the cell below, I've put 0:7:52.
Adding both cells (inside a cell with the mentioned cell formatting) yielded 0:10:16.
=9.76 value(minutes)
=24*60 number of minutes in a day
=A1/A2 formatted as time
Will show 12:09:46. You can use =MINUTE(A3) to extract the minutes and =SECOND(A3) for the seconds.
Actually if 9.76 means 9 minutes and 76 seconds, you'll need more formulas to extract the minutes and seconds then add them together. You can use =Floor() to get the integer. Subtract to find the .76 and multiply by 100 to get the number of seconds. Then divide by 60 to convert to minutes and add to the 9 whole mins. Now you have the number of mins which you can convert to a time value per the above.
EDIT:
You need to enter in Excel as 0:02:12 then you can add quite nicely. If you don't want to re-enter everything you can do this: =VALUE("0:"&SUBSTITUTE(A1,".",":")) then add. Be sure to convert each individual value BEFORE adding otherwise you might get incorrect results.

Controlling Excel time format input/output

Background: I have been officiating our local jogging events for about ten years now. I am responsible for handling the data of the participants (name, sporting club, bib number) split into their categories (age bracket+gender, distance). The main task is collecting their times, and processing that data (sorting the runners within their category etc). I can handle this with Excel mostly fine.
Problem: What is the ideal time format for entering the race times of the participants? The times are either in the format mm:ss or (for slower runners and/or longer distances) h:mm:ss. Excel doesn't seem to have a built-in format where the hours field is optional. For optimizing my workflow ideally I would like to have a cell format such that the input
47:12 is to be interpreted as 47 minutes and 12 seconds, and the input 1:09:38 is to be interpreted as 1hr 9 minutes and 38 seconds. However, Excel, with the best fitting cell format that I found, will insist that the input 47:12 means 47 hours and 12 minutes. For times exceeding 1 hour I would input 1:03:00 if I meant that the seconds field is to be left with value zero.
How to make Excel realize that when the format can handle up to three numbers as inputs, it would, when given only two numbers, move them towards the end?
Thinking: I "can" key in 47 minutes and 12 seconds as 0:47:12 all right. But because most of the times are under 1 hour, that is partly wasted effort. Also, using such a format the data is displayed on the screen together with that superfluous 0:. What's worse (IIRC) those leading zeros
also appear in the printed versions, which is strange (insulting even) in a shorter distance for junior participants.
My hack: I enter the times as general numbers in the mm,ss format (in these parts a comma serves as a decimal separator). Excel can sort those as numbers just fine. I then duplicate the data of that sorted column to another "printable" version (formatted as text), where the data is just copied, but I correct the times exceeding 60 minutes by hand. This works just fine as long as I'm not in a hurry (our event is not exactly Boston Marathon, say, less than 200 participants), and remember to hide the column that is not supposed to be printed. This is kludgy, and there have been accidents, when other officials have been rushing me to get the results printed.
I managed to create a format where the hour-field is optional. It works with a conditional format. First you format your cells as standard, so you get the times as comma-values. After that you create a conditional format for these cells, which has two rules:
if cellvalue > 0.04166667 format hh:mm:ss
if cellvalue < 0.04166666 format mm:ss
Result:
47:12
01:09:38
01:00:00
So you get what you really want and you can use the original values for sorting and so on.
EDIT:
For the input you need four additional columns. You enter the times as you want, e.g. 47:12 and 1:09:38. In the next three columns you split these values in hour, minute and second, whereby the interpretation limit is 3 hours (03:00), which is 0.125.
So, these are the formulas for the split columns (your input is in B1):
Hours: =IF(B1>0.125,0,HOUR(B1))
Minutes: =IF(B1>0.125,INT(B1)*24+HOUR(B1),MINUTE(B1))
Seconds: =IF(B1>0.125,MINUTE(B1),SECOND(B1))
And finally, you put all values togehter in the forth column:
=TIME(C1,D1,E1)
and use the conditional format above.
If you will be entering your data as
`mmm,ss`
where the comma is the decimal point, then you can convert it to "Excel Time" with the simple formula:
=DOLLARDE(A1,60)/1440
Format the result as you wish.
If you want everything displayed as h:mm:ss then use that as your custom format (Format > Cells > Number > Custom Type:...)
If you want h to be displayed only with values of 60 minutes or greater, then use
[<0.0416666666666667]mm:ss;h:mm:ss
for your cell's custom format.
Beware that seconds must be entered with two digits always. In other words
6,2 will translate to 6 min 20 sec.
6,02 will translate to 6 min 2 sec
I really like IQV's answer above, but as pointed out in the comment section, the leading zero will be required for the data entry side. If for whatever reason this is not acceptable you can use the following ugly formula to convert your time entered in your usual method of mm,ss to hh:mm:ss with the hh: being displayed as required. Unfortunately it converts the whole thing to text which means you can no longer perform math operations on it.
=IF(FIND(".",MOD(D2,60)&".")=2,"0","")&MOD(D2,60)
and since you use , as your decimal separator the formula would become:
IF(FIND(",",MOD(D2,60)&",")=2,"0","")&MOD(D2,60)
If you use ; as your list separator then your formula becomes
IF(FIND(",";MOD(D2;60)&",")=2;"0";"")&MOD(D2;60)
There are probably some cleaner formulas, but that will get you started. Just replace D2 with the location where your time is stored.
Again I still prefer IQV's answer as you can do much more with the time information when its stored as a number and not text.
Option 2
lets say you change your data storage method to hhmm,ss in cell D6. you could rip apart the information and reassemble it in a display friendly version as follows.
=IF(FIND(".",D6)<=3,LEFT(D6,2)&":"&RIGHT(D6,LEN(D6)-FIND(".",D6)),LEFT(D6,FIND(".",D6)-3)&":"&MID(D6,FIND(".",D6)-2,2)&":"&RIGHT(D6,LEN(D6)-FIND(".",D6)))
you will need to substitute your list separator for the , and then substitute a coma for the decimal.

Excel - Evaluate multiple cells in a row and create report or display showing lowest to highest

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.

summing time excel spreadsheet not working

I have a issue with excel, I am trying to add up time so they can be displayed correctly in the spreadsheet that I am making, I have requests from user and give them how long it will take to change or fix. on the sheet I am displaying 01:00:00 which means the time taken is 1 hour, and displaying the sum usinfg =sum(A1:A10) which adds up fine when the time is under 24 hours, but if the sum is grater is show up as 03:00:00, i would like to know if it is possible to show time as 27:00:00 which means 27 hours the change will take. not three how would i allow this to be displayed
youu need to use the following custom cell format : [hh]:mm:ss

Excel 2007: How to display mm:ss format not as a DateTime (e.g. 73:07)?

I need to create and Excel table that computes daily training times. each row has the following fields: Date, Distance, Time and Minutes/Km. My main problem is that I want to display the Time in format of mm:ss. For example: 24 min and 3 sec should be 24:03, but "Excel" turns it to 00:03:00 (3 min after midnight). I've tried setting up "special formatting" but still "Excel insists" on formatting the hours. More over, training may exceed 60 minutes and I still want it only as mm:ss
My second question is after I'm done with the formatting issue, what is the simple way to compute Time/Distance?
enter the values as 0:mm:ss and format as [m]:ss
as this is now in the mins & seconds, simple arithmetic will allow you to calculate your statistics
Excel shows 24:03 as 3 minutes when you format it as time, because 24:03 is the same as 12:03 AM (in military time).
Use General Format to Add Times
Instead of trying to format as Time, use the General Format and the following formula:
=number of minutes + (number of seconds / 60)
Ex: for 24 minutes and 3 seconds:
=24+3/60
This will give you a value of 24.05.
Do this for each time period. Let's say you enter this formula in cells A1 and A2. Then, to get the total sum of elapsed time, use this formula in cell A3:
=INT(A1+A2)+MOD(A1+A2,1)
Convert back to minutes and seconds
If you put =24+3/60 into each cell, you will have a value of 48.1 in cell A3.
Now you need to convert this back to minutes and seconds. Use the following formula in cell A4:
=MOD(A3,1)*60
This takes the decimal portion and multiples it by 60. Remember, we divided by 60 in the beginning, so to convert it back to seconds we need to multiply.
You could have also done this separately, i.e. in cell A3 use this formula:
=INT(A1+A2)
and this formula in cell A4:
=MOD(A1+A2,1)*60
Here's a screenshot showing the final formulas:
To make life easier when entering multiple dates/times it is possible to use a custom format to remove the need to enter the colon, and the leading "hour" 0. This however requires a second field for the numerical date to be stored, as the displayed date from the custom format is in base 10.
Displaying a number as a time (no need to enter colons, but no time conversion)
For displaying the times on the sheet, and for entering them without having to type the colon set the cell format to custom and use:
0/:00
Then enter your time. For example, if you wanted to enter 62:30, then you would simply type 6230 and your custom format would visually insert a colon 2 decimal points from the right.
If you only need to display the times, stop here.
Converting number to time
If you need to be able to calculate with the times, you will need to convert them from base 10 into the time format.
This can be done with the following formula (change A2 to the relevant cell reference):
=TIME(0,TRUNC(A2/100),MOD(A2,100))
=TIME starts the number to time conversion
We don't need hours, so enter 0, at the beginning of the formula, as the format is always hh,mm,ss (to display hours and minutes instead of minutes and seconds, place the 0 at the end of the formula).
For the minutes, TRUNC(A2/100), discards the rightmost 2 digits.
For the seconds, MOD(A2,100) keeps the rightmost 2 digits and discards everything to the left.
The above formula was found and adapted from this article:
PC Mag.com - Easy Date and Time Entry in Excel
Alternatively, you could skip the 0/:00 custom formatting, and just enter your time in a cell to be referenced of the edge of the visible workspace or on another sheet as you would for the custom formatting (ie: 6230 for 62:30)
Then change the display format of the cells with the formula to [m]:ss as #Sean Chessire suggested.
Here is a screen shot to show what I mean.
If you are using hand inputted data, you can enter your data as mm:ss,0 or mm:ss.0 depending on your language/region selection instead of 00:mm:ss.
You need to specify your cell format as [m]:ss if you like to see all minutes seconds format instead of hours minutes seconds format.
as text:
=CONCATENATE(TEXT(cell;"d");" days ";TEXT(cell;"t");" hours ";MID(TEXT(cell;"hh:mm:ss");4;2);" minutes ";TEXT(cell;"s");" seconds")
5.In the Format Cells box, click Custom in the Category list.
6.In the Type box, at the top of the list of formats, type [h]:mm;# and then click OK. (That’s a colon after [h], and a semicolon after mm.)
YOu can then add hours. The format will be in the Type list the next time you need it.
From MS, works well.

One convenient trick to entering elapsed times into Excel is to have two zeros and a colon before the number of minutes, details follow. For copy and paste operations into Excel without have to worry about formatting at all one can use the format 00:XX:XX where XX are two digits totaling < 60. In that case, Excel will echo 0:XX:XX in the cell contents displayed and store the data as 12:XX:XX AM. If one pastes data in a 00:XXX:XX format into Excel, or 00:XX:XX where either XX > 59 this will be converted into a fraction of a day.
For example, 00:121:12 becomes 0.0841666666666667, which if multiplied by the number of seconds in a day, 86,400, becomes 7272 s. Next, 00:21:12 would by default show 0:21:12 stored as 12:21:12 AM. Finally, 00:21:60 becomes 0.0152777777777778, also a fraction of a day.
This suggestion is made merely to avoid having to worry about specific formatting in Excel, and letting the program worry about it. Note, for Excel data internally formatted as 12:XX:XX AM one can only use certain Excel commands, for example, one can take an average. However, subtraction will only work when the result is a positive number. Such that converting times into seconds, fractions of a day, or other real number is suggested for access to more complete arithmetic operation coverage.
For example, if one has a column of mixed time formats, or times that are negative and will not display, if one changes the number formatting to General, all the times will be converted to fractions of a day.
