Rolling Time Formula - Possible To Fill In Gaps

Jul 30, 2014

I have attached a work sheet where I have part of a formula working.

Although what I am trying to achieve is in the example in column B.

It is possible to fill in the gaps as in column B with the task between the time frames.?

Fill In Of Text Gaps

Mar 21, 2007

I have a sheet of over 40000 rows, I attach a sample. Column a is called dam and column b is called damsire. Each dam has only one 1 damsire. Both column a and column b are sorted ascending. Unfortunately there are big gaps in column b. some of these can be filled in as we have the information e.g. b38 and b39 should be the row 37 tells you the correct damsire. Similiarly b49 could be filled in as shernazar. I want to create a new column which contains a formula to fill in these blanks. of course some of the blanks cant be filled in as the information is not there e.g. b23 to b28.

Fill In Gaps - Missing Days In Range

Mar 29, 2012

I get given a csv file on a monthly basis which contains consumption data per day for the specified period. This sounds simple but on occasion (more often than not) the data has missing days. This can cause me problem later on in my analysis.

I can happily total the monthly consumption using the date and month text. What i want to do however is to sort the csv file into daily consumption and highlight the missing days i.e. have a range of the days in the month and allocate the daily data to the correct date. I currently do this manually but know that there must be a better, automated approach... searching for matching dates for example?

In my head i'm thinking the following approach but lack the coding skills to do it.

1. Define the start and end dates. Perhaps count the number of days between the two dates and autofill the start date down the appropriate number of days in column A?

2. Paste the csv file into a different sheet and, starting from the top, cut and paste the csv data to the correct date created in step 1. Do this for each row based on the csv data.

Handling Gaps In Time Series Data

Dec 21, 2006

I have been browsing here off and on, and have found many excellent answers. I use Excel to process data on time series, as an adjunct to consultancy work on statistical analysis of industrial data . Usually the data has irregular gaps, e.g., daily data might have 2-10 day gaps. If I want to take, say, 7-day averages, SKIPPING OVER gaps longer than 2 days(say), is there an easy way to do this (I don't really know VBA,and it is not worth my time to try and write long code for this, which will eventually be done by some professional programmers)!

Find Time Gaps Greater Than "X" Minutes.

Jan 21, 2009

I get sheets, sometimes 10 records, sometimes 1,000 records. And there is a time column. It's formatted as: hh:mm:ssam (09:12:36am). Now what I need to do is find a way to highlight any record that has a large gap between itself and the record before it. This gap amount can be variable, but for the explanation lets say, I need to highlight any record that has a gap of 5 minutes greater than the time before it.

I've tried a formula I found elsewhere:

=F3-F2> 1/24/60*5

But it just returns "#VALUE!".

I'm completely stumped, and since about last week, 1 of my daily responsibilites will be analysing anywhere from 10 - 50 sheets a day.

The guy before me would open the sheet and manually find it by literally looking from record to record. This was this 1 guy's full time job. From what I'm reading around there are ways to have excel do this for me with a simple formula and conditional formatting.

Rolling Total Formula

Aug 18, 2009

Whenever I add new data I need two cells of the old data to not be counted. This should continue until old data isnt being counted anymore.

New Data entered Cell C36:E36 (148, 147, 214)
Old data shouldnt be counted anymore from Cell C67:E68 (137, 152, 156, 94, 117, 158)

Total before New data Entered: 14066
After New data Entered: 13761

This formula is required for a total of 16 weeks or until all the old data isn't being calculated anymore in my rolling total.

I only need one total the three examples are just showing what the total should be calculated.

Sheet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xamples140661376113305Excel 2007

Average Formula For Rolling Range?

Jan 24, 2014

I am trying to create a formula that looks for the last populated cell, counts 12 cells back and returns an average for all of the cells in that range. I know I have done this before with some combination of INDEX and COUNT, but I can't seem to remember how I did it and my experimenting is not proving fruitful.

CreatE A Formula That Would Total A Rolling 90 Day

Dec 3, 2008

I am trying to do is create a total of only the last 90 days of entries from a list of $ amounts. Attached is an example. We are going to start keeping track of our cashiers variances but at the top of the sheet we only want to know what their last 90 days of entries equal.

This would be considered a rolling 90 days, so older variances drop off after 90 days, they would still be left on screen but would not effect the main total.

Formula For Rolling 12 Month Average?

Mar 16, 2010

See Attached.

The YTD 10 column is fine that will change everytime you update each month. I was wondering if there was a formula I could use for the Rolling 12 month Column.

At the moment it is averging from Mar 09-Feb10 which is correct but when it comes to putting in data for Mar 10, the Rolling 12 month column will obviously not change.

Is there a way of moving the formula along one each time you input data into a new month. So when Mar 10 has been entered the rolling 12 month column will pick up Apr-09-Mar-10 then when Apr 10 has been entered the formula will change again to May-09-APr-10?

Auto-Populate Formula For Rolling Range Of Cells?

Jul 25, 2014

I have a column of values (E4:E87). I'm adding 1 value to this column manually each tomorrow (July 24th) I will have E4:E88...and so forth. Each day is a new row.

In column Z (i.e. cell Z87) I have the formula =(SUM(O53:O87))/(SUM(E53:E87)). Z88 will have
=(SUM(somevalue:O88))/(SUM(somevalue:E88)). This gives me a resulting percentage for a rolling period of time.

I need an automated way to populate "O53" and "E53" ("somevalue") in the formula so that the SUM of the current row's cell (i.e. E88) through [whatever] is 50 or greater. (The sum of the values should be as small as possible, but at least 50, and should not include any older values than absolutely necessary for it to equal at least 50.)

Rolling & Average (write A Single Formula That I Can Copy Down)

Mar 2, 2009

I've got a "Date" Column which has every day of every month, and next to that several columns with different types of data to correspond to a particular date.

To simplify this (because there are TONS of dates), I've made another "Date" column that displays only every 5th day. Now what I'd like to do of course is average the corresponding data over five days.

I don't know how to write a single formula that I can copy down that will do this.

I've attached a sample spreadsheet with only one month's data, the stuff I need a formula / code for is in red

Gaps In A List

May 13, 2006

I'm having a problem with a list that I've created. The list is in cell A1, the base data for the list is in the range B1:B50. The problem is that data in this range is dynamic, i.e. it has formulas and depending on the result of these formulae the cells in the range either have a value or the cell is left blank. The problem this causes is that the list ends up having gaps in it because it uses blank cells as well. And this is despite me specifcally ticking " Ignore Blank " in the Data Validation menu where I'm creating the list.

Anyway To Make Auto Fill Time Value Static

Jan 24, 2009

I have 2 cell, A1 and B1. When any data is entered into A1, B1 will display the time corresponding to when the data was entered.

I was thinking about function for B1 would be "=IF(A1="","",now()) ". It worked such that it will display the time, however the value in B1 will automatically update itself if I were to randomly input any data in any other cell too.

For example, I input "testing" in A1. B1 display "11:20PM". Ten minutes later, I input "hello" in A2. B1 now display "11:30PM".

Anyone know a way to stop B1 from updating? or only update when new data is entered into A1 only?

Drop-Down Lists: Can We Fill 2 Columns At The Same Time?

May 13, 2009

Is there a way to have a drop-down list fill two columns (actually, two adjacent cells) when a selection is made from the drop-down list? Maybe using an array in the source formula?

For instance, let's say I pick a doctor from the drop down list, I would like the doctor's practice to automatically fill the cell next it so that the two always go together correctly. In the lists example below, when I select Dr. Elmer in column A, then I want Internal Medecine Associates to go in column B.

MD Practice
Dr. BartholomewCentral Endocrine Specialists
Dr. Elmer Internal Medicine Associates
Dr. StamfordCardiology Associates

Drag Formulas With Gaps?

Mar 13, 2014

I'm wanting to do is drag a formula down and it drop to the next cell rather than the same row number I'm on. For example I'm trying to concatenate a list of phrases whilst changing the main word. Here's an example of the excel sheet

Base Terms

There is meant to be a space after the second red and blue enabling me to make (in order), red car, blue car, car red, car blue

How can I make it so I've done the relevant concatenate formulas for A2 with the B column and simply drag it down and Excel will switch from A2 to A3 and so on when I've dragged out the 4 formulas?

Find Gaps In Sequence

Dec 31, 2008

I have a file that contains addresses in column C. I need to find any gaps in addresses.

211 Corbin Dr
213 Corbin Drive
214 Corbin Drive
123 Apple Drive
124 Apple Dr
124 Apple Dr
127 Apple Drive

I want to identify that there is a gap between 211 Corbin and 213 Corbin and 124 and 127 Apple Drive.

Currently the address including house number are in column c. However, I split the house number into a separate column and the street address in yet another column. There are also duplicates which I have identified by using conditional formatting to highlight the duplicates.

2012/05/01 00:18:00

There are data entries next to these time stamps. I am able to create just the time stamps starting at the beginning and ending at the end of the month but I need it to fill in missing entries in a data set. The code below works but only some of the time. I have tried a few different things but nothing works.

Sub Insert_missing_3min()
'Inserts a row with the date and time where the missing date and time stamp is and a zero next to the date added.

Dim min3 As Date
Dim CurTime As Date

Dim NextCell As Date

min3 = 3 / 24 / 60

Count Gaps Between Values And Highlight Cells?

Jul 17, 2014

The solution can be either in VBA or conditional formatting, if possible.I have product names on column A and weeks as from column B where I have the quantity sold. So, every week I'll have an additional column.

A B C D E ...
Product Week1 Week2 Week3 Week4...

What I need:

If the cell is filled, highlight it in green.

If the gap (empty cells) between weeks is =1, highlight it in yellow

If the gap (empty cells) between weeks is >1 but <2, highlight it in orange

If the gap (empty cells) between weeks is >2, highlight it in red
