I am looking for a solution to the following Problem.
I have a table with 2 columns and I need a macro to check if the rows that have same values in first column, also have the same values in another column and give an error message if not.
For example,
1. a 12
2. b 1
3. c 567
4. a 12
5. c 567
6. c 567
7. b 1
If for example in the 7. row the value in the second column is "2", then the error message will appear.
Any ideas how to do that?
Use data validation as Custom based on Formula:,
=isnumber(match(<relative cell address of top cell>, $a:$a, 0))

I am trying to lookup values from Table 1 to Table 2 based on Col1 in Table 1.
The catch is that Table 1 has duplicate values (for example, A is repeated 3 times) but I don't want to duplicate the returned value from Table 2.
How can this be done through either excel or sql (e.g. LEFT JOIN)?
What SQL are you using? Are you familiar with CTE and partition?
Have a look here: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/597b876e-eb00-4013-a613-97c377408668/rownumber-and-cte?forum=transactsql
and here: (answer and 2nd comment): Select the first instance of a record
You can use those ideas to create another field that tells you whether the row is the first, 2nd , 3rd etc occurrence of Col1. Eg you'd have something like
1 B Red 150
2 B Red 150
and you can then update col3 to be zero where this new field is not 1.
EDIT: since you asked about Excel: in Excel, sort by whatever criteria you may need (col 1 first, of course). Let's say that Col1 starts (excluding the heading) in cell C2. Set cell B2 =1. Then write this formula in cell B3:
=IF(C3=C2,B2+1,1)
and drag it all the way down. This will count the occurrences of col 1, ie it will tell you which is the first, 2nd etc time a given value appears in col1. You can then use it as as the basis to change the value in other columns.
Also, it is not good practice to have a column where the first cell has a different formula from the others. You can use the same formula nesting another IF and referencing the row, so as to set one formula for the first row and one for the others.
Have to create a column next to existing column. my present table is like this
and result needed is like this. Each date value is getting repeated 3 times and getting incremented by 1
Pick any cell and enter:
=DATE(2018,8,21+ROUNDUP(ROWS($1:1)/3,0))
and copy downward.
Here our start cell is one cell to the left of the 21.
Manually type in the first 3 into A1:A3 (or rows 1 to 3) in A4 (or row 4) reference A1 (row 1) and add 1 to it. Then drag the formula down.
The formula should look like =A1+1
I have three excel spreadsheets. The first has the values that are to be assigned to a new excel spreadsheet. The second has the column that the data belongs in. The third has the row that the data belongs in.
It looks something like this:
Data Value:
1 5 7 9
2 2 6 8
Column Number:
1 2 3 1
2 3 1 2
Row Number:
1 2 3 2
4 4 3 1
How can I combine all of this information to create a single spreadsheet that contains the values in a format like this:
Column
1 2 3
Row
1 1 8 0
2 9 5 0
3 6 0 7
4 0 2 2
I have tried to do it by using loops in vba, but I am a beginner and I am having some difficulty.
I know that I need to use a loop that checks the row and column that the data is supposed to be in against the row and column for each iteration. I am just not sure how to go about doing that.
Assuming these are different sheets in the same workbook (if not - create a new workbook and copy the sheets over). I assume that on each sheet, the same range of cells is used (for example A1:D2 in all 3 cases with the values on the first sheet, the column numbers in the second and the row numbers in the third). You can dispense with VBA entirely at the expense of using some complicate formulas (inspired by this excellent article: http://exceluser.com/blog/1043/how-to-create-two-dimensional-lookups-in-excel-formulas.html )
Step 1. Add a fourth sheet and in A1 add the formula
=CONCATENATE(Sheet3!A1,"_",Sheet2!A1)
and copy it over the appropriate range (e.g. A1:D2). This will give you things like 2_1 which tell you that the corresponding entry in sheet 1 belongs in row 2 column 1. Name this range "location" (formula tab - define names option)
Step 2 - Decide where you want to hold the data (I'm assuming it is in sheet 4 for simplicity) And add the row numbers (1-4) and the column numbers (1-3) as labels. In my case the row labels are in A5:A8 and the column labels in B4:C4 (see the screenshot below). Then in the upper left corner of the values to be filled in (B5 in my case) enter the following formula (suitably adjusted to match your ranges):
=IFERROR(INDIRECT(ADDRESS(SUMPRODUCT(ROW(location)*(location = CONCATENATE($A5, "_",B$4))),SUMPRODUCT(COLUMN(location)*(location = CONCATENATE($A5, "_",B$4))),,,"Sheet1")),0)
and copy it over the intended range. Be careful with the dollar signs - this formula mixes row absolute and column absolute references in an essential way. Somewhat oddly, it actually works:
I am trying to figure out if there are any differences between a list of data with another. In order for a row of data to "match" with another row, the row must have the same values in their corresponding column. The rows themselves do not have to be in any particular order. In particular, I am dealing with a parts list, where there are part numbers, descriptions, etc. I am trying to figure out if any rows of data are different from rows of data from another list.
I found Compare two sheets using arrays, which may have the answer to my problem, but I am having trouble figuring out how to adapt to my code due to inexperience in Visual Basic.
I was able to get it to work for a single column of data, comparing one column of data from one sheet to another, but cannot get it to compare entire rows of data.
Here is an example of I want this to work:
Sheet 1 Sheet 2
Column 1 Column 2 Column 1 Column 2
Row 1 22a 33 11 11
Row 2 22a 33a 22a 33
Row 3 55 22b 55 23b
The code in the link will tell you what is not in sheet 1 but in sheet 2 and vice versa. In this example, I would like the code to tell me Sheet 1 Row 2 and Sheet 1 Row 3 are not in Sheet 2, and Sheet 2 Row 1 and Sheet 2 Row 3 are not in Sheet 1 (Sheet 1 Row 1 and Sheet 2 Row 2 match).
If that is ok by you, you can do it without VBA using the following formula:
={IF(IFERROR(MATCH(A1&"|"&B1;Sheet7!$A$1:$A$3&"|"&Sheet7!$B$1:$B$3;0);-1)=-1;"Unique";"")}
Assuming that each of your tables start in A1 (so that the tables with three entries span A1:B3), and entering this formula into C1 (and copying it down), press CTRL+SHIFT+ENTER when entering the formula to create an array formula, this will show the word "Unique" in column C if the pair in that row on that sheet is not in any of the row-pairs on sheet 2.
You can then use conditional formatting to highlight unique rows, filter on the tables to include only unique rows, or some other way of doing what you need.
NOTE 1: I have entered my numbers in Sheet6 and Sheet7 instead of 1 and 2. The formula written above goes into Sheet6.
NOTE 2: My language use ; instead of , as function separator, so if yours use , you need to change that.
NOTE 3: You will need to expand the ranges Sheet7!$A$1:$A$3 and Sheet7!$B$1:$B$3 if your set grows (this will happen automatically if new rows are inserted in between the old ones). The best is still probably to create named ranges for each of the 4 columns, exchange the references with those, and manage the named ranges instead of the formulas.
NOTE 4: If your data set contains the character "|", you need to change that as well, to match some character that you for sure do not have there.
Alternatively you could in column C on each cheet enter (assuming first entry in C1)
=A1&"|"&B1"
and copy this down, then run the solution from your copied example using that C column instead of on A1 and B1.
I have 5 sheets in an excel file named
roll 1to2.5
roll2.5to5
roll5to7
roll 7to9.5
roll 9.5to12
Each sheet has two columns with the following data:
A B
1 22
2 25
3 29
4 20
5 18
6 26
7 19
8 16
9 21
10 20
Now I have been able to do the following: In column C, if I enter a number from Col A, say "7", i get the corresponding value from Col B i.e. "19". I used the following formula
=VLOOKUP(C5,A1:B10,2,FALSE)
This works good uptill here.
Issue 1: Let's say I want to enter the roll in a cell say "5.5", it should automatically consider data from sheet 3 (roll5to7)
Issue 2: and then if I enter a value of ColB, say "20", it should pick up the corresponding value from ColA i.e. "4" (first match) in sheet 3.
How can I achieve this?
To get the right sheet name list your 5 sheet names in one column and in the previous column the lower bound for each (1, 2.5, 5, 7 and 9) and name that two column table Table
Now you can use this formula
=VLOOKUP(C5,INDIRECT("'"&LOOKUP(D5,Table)&"'!A1:B10"),2,FALSE)
where D5 contains the roll
LOOKUP finds the correct sheet name and INDIRECT converts text to a valid reference
Edit:
If you want to look for C5 in column B and find the corresponding value from column A then INDEX/MATCH would look like this:
=INDEX(INDIRECT("'"&LOOKUP(D5,Table)&"'!A1:A10"),MATCH(C5,INDIRECT("'"&LOOKUP(D5,Table)&"'!B1:B10"),0))
