Averages, Mins And Max On Colums With An Insane Amount Of Rows
Apr 22, 2009
I have a problem with a data set that I'm working on. Basically, I've got a data set that was downloaded from a weather station. I need weather data like average temperature, maximum temperature, minimum temperature for each day over a 90 days period. This is simple enough.
The problem, however, is that the weatherstation has been sampling every 5 minutes. In the data sheet, each day is represented by 12*24 rows of data (12 samples per hour times 24 hours). The total dataset across all days is something close to 26000 rows!
Of course, I can spend hours doing all this by manually by average(), min() and max() and then selecting the cells I want it to apply to each time, but the thought of doing so makes me wince. I would have to do it 90 times per column across hundreds of cells each time and I'm after much more than just temperatures.
Is there a less labour intensive way of doing this?
I am copy a range of data (15000 rows, 9 columns) from a worksheet to another worksheet in the same workbook. But it's taking extremely long. I am simple copy and pasting as values. That's all. Is this normal? Is there anyway to speed up this?
I have a workbook of which has different times in columns D and E. What im trying to do is where the time difference between the columns is LESS than 5 mins I need that row deleting and cells shifting up.
I.E lets say D14 is 05.24 and E14 is 05.50. I need that line keeping but if E14 was lets say 05.27 then I need that line deleting and cells shifting up.
I need to be able to do this right down the workbook until the last entry.
I have a sheet with products and information regarding these products. It is consistently build up in a 5-row information block per product like:
A1: name A2: info A3: price A4: to be deleted A5: to be deleted
What I want:
A1: name B1: description C1: Price
For product 2 it should: A6 -> A2 A7 -> B2 A8 -> C2 A9 -> to be deleted A10 -> to be deleted ..etcetera
The Macro should loop until no data is found in the A column. Note: some of the 2nd rows (information) are not filled. They can't be deleted but need to be left empty!
I have a parts index containing 500+ rows of data, I also have multiple columns in which I can sort the data.
I would like to have a button fixed in cell C4, D4, E4, etc... row 4 is the header, that when clicked, will filter all rows that have a selection (non-blanks) for only that column. So If I have data in various rows & column (C5:F500) that when I click on the button in cell D4, only the data listed in the various rows of D5:D500 are shown and columns C, E & F are hidden. Clicking cell D4 will show all data.
I can create the button so that it is sized specific to the cell and follows the cell sizing and I can create a button to filter only columns D or E or F, etc... but that means that each button is a separate VBA, macro.
A while ago I found a VBA code that allowed me to sort rows Asending/Desending depending on which button in which column was clicked... See inset: and this allowed me to add columns without changing the code. So I think If I can modify this code this will work great for me..
Sub SortTable()
'code written by Dave Peterson 2005-10-22 '2006-08-06 updated to accommodate hidden or filtered rows Dim myTable As Range Dim myColToSort As Long Dim curWks As Worksheet Dim mySortOrder As Long Dim FirstRow As Long Dim TopRow As Long Dim LastRow As Long Dim iCol As Integer Dim strCol As String Dim rng As Range Dim rngF As Range
I have a spreadsheet with 20+ columns. Each column contains a list of invoice numbers, eg, 1234. The lists are all of different lengths (see below). I want to find a way to find/highlight/identify those invoice numbers that appear more than once in the entire sheet (eg if invoice 1234 is listed in column B, and also in column H, and/or if invoice 5678 is listed in column A, and also in column J, and also perhaps in column D, etc.)
I've searched this forum but haven't found anything about searching for multiple duplicates in multiple columns. Ideally the matches would be highlighted in different colours, (eg all cells that contain 1234 would be red, those that contain 5678 would be blue, etc., for ease of identification) but I'm not sure if that's possible. I've attached an example that I've shaded myself to show what I mean. I've tried the MODE function but that only tells me which invoice number occurs the most.
I routinely have do download massive data sets of reporting that is saved as an excel spreadsheet. The three columns of sample data attached are Report Numbers, Report Evaluation Serial Numbers, and Report Evaluator ID.
As seen in the attached spreadsheet, there can be multiple Report Numbers (in same field separated by comma) which have been evaluated by different Evaluators. It is my responsibility to account for the number of Reports that have been evaluated, and many other metrics from like data. The issue I have is when more than one report number is listed in the same field I need to parse the data into its own field for ease of counting (and also maintain the adjacent data). It is not a problem to merely copy the fields and delete the excess numbers, however when dealing with thousands of Reports, and Evaluators this can be very time consuming. In the attached file I have separated .xls into three workbooks to help explain my problem: Initial state of Data; What I need To Parse Out; and The final endstate I require. I hope that I have explained this issue with enough detail. I am sure that the attached file will explain better.
I have a first column, which contains random integers typically with gaps of between 10 to 50 blank cells. The data may have up to 5,000 rows in total.
In the next column along I would like a calculation which averages the integer in the first column out across all rows until another integer is reached in the first column.
E.g. In the first column, the first number is 60, then 9 blank cells till the next entry. In the second column the first 10 cells each contain the number 6 ( = 60/10).
I have been using this macro to separate lots of rows with a certain amount of blank rows.
Example:
Code: Sub test() Dim j As Long, r As Range j = InputBox("type the number of rows to be insered") Set r = Range("A2")
[Code] .......
I trying to change it so that, instead of inserting how ever many blank rows, it just copys the row above.
Example (Row A to C)
I have been messing around with macro recorder and i could select each row and paste it into the blank rows, but from researching on the internet selecting and pasting data seems to be a waste of resources (ram?) and i will be running this on a couple hundred rows (lots of data). Also, i would like to keep the functionality so that i can still choose how many times it copys/inserts each individual row from a input box.
I eventually want the data to end up like it is shown in the table but i am takin it one step at time because i want to understand what the code is doing.
I have a table which contains a list of branches eg;
01 02 04 06
I then have a spreadsheet which contains a number of columns and rows.
I want to create a new spreadsheet in the first column it will contain the branch from the table above then the rows and columns in the above spreadsheet
The rows and columns would then repeat for each of the other branches in the table. IE if I have 4 branches in my table and 100 rows in my spreadsheet my new spreadsheet would contain 400 rows
I need to know the function to copy an unknown amount of rows. After a certain row it should copy everything.
So like after row A6 it copys every row below it with data in them then I want to paste it in another worksheet. I dont want to just do
Rows("6:65000").Select Selection.Copy
If someone could point me to a good site that explains alot of useful VBA commands that would help me alot. Most of my problems come from just not knowing the full function names.
Located in column W are amounts. if this amount is les than or equal to zero, I want to look at column A to see what account number is associated with that amount. then delete any row with that account number and also any empty row that may be directly above it.
I am trying to summarize some of my data. I have attached file with Sheet "Data", and how it should look in Sheet "Result".
1. If on two rows content in A, B, C, D match exactly, to copy them on sheet Result 2. Also Copy E5 (it will always be the same if the first four cells match, need to include it only once) 3. Also Combine all F cells together with ; (first entry is Develop and Second entry is Test - then in Sheet Result it will become Develop;Test) 4. Also Sum the amounts in G 5. And then Copy all other rows that don't have exact match
There might be 3-4 rows that have exact match on A, B, C, D.
I want to create a macro that will copy and paste a couple seperate collumns but the problem is that each month, and each invoice, contain a different amount of rows so I can't "record" a macro. Lets say I start on A4 which is the heading of Column D..below it are a bunch of records at the end of the records is a space. I need it to stop there. Then do the same for Column G, I, etc. I would like it to copy each column and paste in a new workbook.
Im trying to set up an active running inventory sheet where: (A)the progressive daily sheet cells reference back to the corresponding master sheet cells fluctuating the master values, (B) the same progressive daily sheet cells reference back to a cummulative totals-cell based on whether I added or subtracted inventory. I want to make a copy of the blank "sheet 2" with all of the formulas and move it to the end of the workbook each day and enter new values which will reference back to the master sheet so that I can click on a date sheet and see an individual day's values or click on the master sheet to see the fluctuating inventory on-hand and the cummulative +/- totals of all days combined. I've got a couple hundred individual cells to reference. I've tried and tried but I can't make it work. Heres what I need to do:
I need to reference individual cells from "sheet 2,3,etc" back to a corresponding cell in a master sheet. But I need the values in each cell in "sheet 2,3,ETC" to increase or decrease the corresponding cell values in the master sheet. For example: If the value in the master sheet B5 is 200. Then in sheet 2, I enter +50 in B5, I need the master sheet cell B5 to increase by 50 to 250. I also need a way to decrease the cell value in the master sheet B5 if I enter a negative value -50 in sheet 2 B5. I also want to know if I can reference the same cell values entered in "sheet 2,3,etc cell B5" back to totals columns C5 for adding inventory or D5 for subtracting inventory in the master sheet where the master totals columns would reflect cummulative totals added or subtracted. For example: if the value in sheet 2 B5 is +50, then the value in Master sheet C5 would add 50 to a progressive total. But if the value in sheet 2 B5 is -50 then the value in master sheet D5 would add -50 to a progressive total.
I have a data feed that gives a column of cells formated mm/dd/yy hh:mm These are call entries, what i want to do is count all the occurances each hour, so count all the entries say between 9am and 10am. However the column is very long and holds data for many weeks so i want to be able to ignore the date part of the cell.
I have an entire column with numbers such as 48, 95, 30 etc representing hours. how do i format cell so that these numbers will show, 2days, 3days-23hrs-45mins, 1day-6hrs
Thought it would be easy enough to just right click and format the cell but doesn't seem to have the option *shrugs*.
i have =TIME(LEFT(F17,FIND("h",F17)-1),RIGHT(F17,2),0). which gives a time in the format 9:30PM, or 10:30AM etc. How would i change the formula to give me a time minus 15 mins. Eg, if the above formula gave me 8:45PM, i would want it to show 8:30PM
Formula that will change seconds to hours and mins, example 270 mins would show up as 4 hours 30 mins, not 4.5 hours. My second thing is how can I double the times in the same formula.
If a person does a full day I want the formula to calculate how many hours minus 30 mins for lunch i.e. 7:30 - 4:00 = 8 hours. I have done this and it works fine, the problem comes when a person does a half day i.e. 7:30 - 11:30, this will read 4.5 hours. If this is the case I don't want the 30mins deducted so it should be 4.0 hours worked.
I have high lighted a column in the work sheet (yellow) whereby the user puts an 'x' in the appropriate cell if they are working a half day.
The probem is I cannot incorperate the two formulas in one cell (the Actual hours cell) I have the one formula in the actual hours cell and the other bolted on the end thus giving two different readings.
how do i go about setting a message box to pop up every 10 mins or so prompting the user to close the workbook.? i want it to be as irritating as possible! iv'e had a look at ontime but cant get my brain into gear!also don't some of these timers fire even if workbook closed?
I was messing around with a simple countdown timer and need a little help converting a decimal into a format of #days, #hours, #minutes and #seconds.
Cell A1 has target to countdown to 4/14/2010 12:00:00 AM Cell A2 contains =NOW() Cell A3 contains =A1-A2 with the result being 69.4021441 with the amount of decimal places varying depending on when it is refreshed.
I'd Like the result in A3 to read something like "There are 69 days, XX hours, XX minutes and XX seconds until event"
Look at the total in Cell A2, B2 and so on..... and multiply by the numbers below - then add them together at the end.
Problem im having is i cant seem to copy and paste the original formula as when i do it for the next row down it wont look at ROW 2, it will look at ROW 3, ROW 4 etc..
