I have a 2000X10 matrix, I want to get a the average of the columns of each row and on the 11th column put all the averages, thus have a 1X2000 matrix with the averages
How can I do that most efficiently? without just doing this
=AVERAGE(A1,B1,C1,D1,E1,F1,G1,H1,I1,J1)
This is shorter and easier to read:
=AVERAGE(A1:J1)
Just follow these steps:
In column k row 1 you can use =AVERAGE(A1:J1) to take the average of columns 1 through 10
Then copy that value by clicking that cell and pushing ctrl+c on the keyboard.
Next, left click on cell K2 just below where you took your average.
Scroll down to the button of your sheet and
Hold down SHIFT and left CLICK the last row (row 2000) in column k.
Paste with ctrl+V to fill in. Excel will automatically update the equation to take the average of the rows.
For minimal keying: select your eleven columns, Insert > Tables - Table, OK, select the top blank cell of your 11th column, Home > Editing - AutoSum, append "/10" in the cell contents window and Enter.

I need to subtract the minimum of that column from all rows of the column in Excel. I have one million rows and I cannot drag the right corner of the cell box all the way down to apply the formula to all those cells. I unfortunately haven't found anything that works. I want to subtract the minimum of a column from each cell of that column divide by 1000 and store in another column:
=(B1-MIN(B:B))/1000
How do I apply this to all rows of the column where I want this to work?
How do we apply formulas in general to all rows of a column in general?
Several ways to apply a formula to a new column in a large data set:
Option 1 - turn the data into a table: Assuming the data has headers, select the data and hit Ctrl-T or use Insert > table and tick the box "My table has headers". Now enter a name for the new calculated column and below the header enter the formula. It will automatically be applied to all rows in the table.
Option 2 - Enter the formula in the first row of next empty column of the data range. Then double click the fill handle (the lower right-hand corner of the selected cell) to fill the formula all the way down to the last row of the data range
Option 3 - Select the cells where the new formula should go. Easiest might be to start at the bottom end of the data and use Ctrl-Shift-up arrow to select up to the top. Adjust the selection to suit and hit Enter or Shift-Enter to make the top cell the current cell. Enter the formula and confirm it with Ctrl-Enter. It will be applied to all selected cells.
Copy the column, say it's A. In a couple of spare cells enter:
=MIN(A:A)
and
1000
Copy the formula cell, Paste Special..., Values over the top. Copy that cell, select the copy of ColumnA, Paste Special..., Operation Subtract. Copy the cell containing 1000, select the copied column, Paste Special..., Operation Divide. Filter ColumnA to select blanks and delete the contents on the copied column for the selected rows.

I have 3 columns of data in Excel spreadsheet, column 1 is Business Unit, column 2 is item_ID and column 3 is Cost. Column 2 and 3 have data in all rows but column 1 only shows business unit once then the rest are blank until the business changes. I can just drag the business unit data and control down to the blank ones for EACH business unit, but what if I have thousands of rows and more than hundreds of business unit? That will take me forever to do. Is there a way to do this task faster?
Let's assume the data below:
Step 1: select from cell A2 to A31 (all the data rows under Unit column)
Step 2: Click on home tab and click Find & Select.
Step 3: Select Go to Special.
Step 4: Select Blanks and hit ok.
Step 5: On the first cell, enter =A2 (equals to the cell above the blank) then hit ctl+enter
Assuming that Column A is your Business Unit column, adding a temporary column next to it and replicating the first value ie B2=A2 then on B3you could use the following formula:
=IF(A3="",B2,A3)
Copy it down to all your rows in Column B. After verifying its accurateness you could copy and paste as value into your column A and then delete Column B. Regards
Warning: Kludge
In Column 4 create a formula that says "If column 1 is blank, make it look like the row above it, otherwise do nothing"
Highlight that cell and hit Ctrl-End, which should take you to the bottom row of your spreadsheet and Shift-Click. This should highlight the entire column.
Hit Ctrl-D, to fill down. You have now copied your formula to all cells in the column.
Click the column 4 header and then copy (Ctrl-C).
Click on the column 1 header and then 'Paste Special' (Ctrl-Shift-V) and then select "Values"
In D1
=A1
In D2
=if(A2="",D1,A2)
Drag down
Copy D1 to D end of data
Click on A1
Paste as values
Delete column D
I need to make this situation happened:
Let's say I have three different tabs, let's call them Atab, Btab and Sum.
In Atab and Btab I have rows of information. In column K, I have a "comment column".
If the comment column in some row is not blank (it has a comment) - I want the whole row to be coppied to Sum tab.
So in the Sum tab I will see all of the rows of Atab and Btab with comments (on K column).
Is it possible? :)
I want the whole row to be coppied to Sum tab.
I'm assuming you mean “the sum of the Atab and Btab should be placed in Sum tab” and with tab you mean a cell. Then the task is easy, use this formula:
=IF(K1<>""; SUM(A1:B1); 0)
I have a libreoffice sheet that I would like to have the rows increase by 1
example:
1
2
3
4
The problem is I know I can do this with autofill but I have 50000 rows and dragging down takes awhile.
Thanks
Assuming that you already have data up to row 50'000, and you have an empty column (I'll use Col. A) for the series.
Jump to the last cell in one of the "used" columns Ctrl + Arrow down (or scroll all the way down to Cell A50000) then move sideways to Col. A and place an "X" in cell A50000. You now have an empty column A, with an "X" in cell A50000.
Go to cell A1 ( Ctrl + Home ). Put the number "1" in cell A1. Put the following (secret!) formula in cell A2:
=A1+1
Copy cell A2 with Ctrl+c
Stay in Cell A2...
Press Ctrl+Shift+Arrow down, The area from A2 to A50000 should now be highlighted.
Press Ctrl+v to paste the formula all the way down...
IMPORTANT!
Press Ctrl+c to copy the just pasted data (A2..A50000).
Press Ctrl+Shift+v to paste the just copied data "over" the original data with "paste special".
In "Paste Special" make sure that you have NOT selected the option: Formulas.
This will now paste all the results of the formulas back as fixed numbers.
This should take less than a minute, of which most of it is waiting for the system to calculate and to paste (I tried it for 1 mio lines..)
By just changing the formula from =A1+1 to =A1+2, jou can jump with 2, so 1,3,5,7,... But I assume that you'll use this column as a reference for sorting, so you can always go back to the original order.
Have fun!
I have an excel sheet which looks like this:
I want to insert row(or cell) below every filled cell. Like this:
I have thousands of records so need to do this automatically. How can I achieve this?
Thanks in advance!
A non-VBA approach would be to make a new sheet, and enter this formula in A1:
=INDEX(Sheet1!A:A, ROUNDUP(ROW(A1)/2, 0))
Then select A1 and A2 (leaving A2 blank), copy it, select twice the number of rows as in Sheet1, and paste.
If you only want values, you could then select column A and copy, then paste special and paste values only.
You could do it in VBA with the following code:
Sub doIt()
Dim numRows As Long
Dim i As Long
numRows = ActiveSheet.UsedRange.Rows.Count
For i = numRows To 2 Step -1
ActiveSheet.Rows(i).Insert Shift:=xlDown
Next i
End Sub
select the raw that contains the data you want to separate by 1 cell at a time.
press F5.
click special.
at the Go to Special dialog box, click "Constant".
right click 1 of the selected cell and insert
Alternatively, I found the following solution from https://www.pcmag.com/article/149833/insert-alternate-blank-rows-in-excel
You can create the blank rows separately and then interleave them with the existing rows by sorting. To start, insert a new column to the left of the existing column A. Enter 1 in cell A1 and highlight column A all the way to the last row that contains data. From the Edit menu select Fill | Series and click on OK. Column A should now contain numbers from 1 to the total number of rows. Press Ctrl-C to copy these cells to the clipboard, click in the cell just below the last of them, and press Ctrl-V to paste. Now highlight the entire data area, including the new rows with just a number in column A. Select Sort from the Data menu and choose the No header row option in the resulting dialog box. Under Sort by select Column A, under Then by select column B, and click on OK. Finally, delete column A. You now have a blank row after every one of the original 1,000-odd rows.
Because blank lines can often cause problems with charts or calculations, you may want a quick way to remove them. You can use a similar technique.
Again, insert a new column to the left of column A and fill a series from 1 to the end of the data. Highlight the entire data area and sort by column B (the first column of real data). This will group all of the blank rows together. Next, highlight the data area again, and re-sort by column A. The blank lines are gone, and your data is restored to its original order. Finally, remove column A.
easy way:
in a free column (example is column A) fill the first 3 rows with 2,4,6
auto fill the column down to the end of your data.
At the end, fill the next 3 lines with 1,3,5
Autofill down the same amount of lines your data is
now select all, data-> sort-> A
wich will sort your data to 1, (empty) 2 (data) 3 () empty
