IF COUNTIF Unique Value + 1st duplicate - excel-formula

I have basic question related with Excel 2016.
I have a huge table which displays names, as shown here
For Column B "Helper" has been used below formula :
=IF(COUNTIF(A:A,A2)=1,"Unique","")
The formula is flagging all unique values, but I want to flag also the 1st duplicate row as well, as shown in here .
I saw that formula on topic "How to get distinct values in Excel (unique + 1st duplicate occurrences)" :
=IFERROR(INDEX($A$2:$A$10, MATCH(0, INDEX(COUNTIF($B$1:B1, $A$2:$A$10), 0, 0), 0)), "")
But the formula is using duplicating list INDEX(COUNTIF($B$1:B1, and is not useful in my scenario due the fact I have millions rows.
In additional I need one value for all unique + 1st duplicating row for latter calculations.
Unfortunately we are limited to Office 2016 and UNIQUE function from Office 365 cannot be used :(
Sound quite simple, but I'm stuck from couple of hours, and any help will be much appreciated.

Excel count Unique ID's between two dates + a distinct count of another column for each ID

I am struggling with an Excel formula. I am trying to count the number of Unique ID's between two dates (I have that formula working), but I also want to count the SignUpRoles for each unique ID that qualified between the two dates. I am using O365.
Here is how I am capturing the UserId counts in K10:14
=SUM(IF(FREQUENCY(IF(Weartime13[RecordDate]>=K5,IF(Weartime13[RecordDate]<=J5,MATCH(Weartime13[UserId],Weartime13[UserId],0))),ROW(Weartime13[UserId])-ROW(A5)+1),1))
Here is the worksheet I am working with: RDS_Report
Screenshot:

So what I mean by adding another 'if' is that in L14 (for example) you would have
=SUM(IF(FREQUENCY(IF(Weartime13[RecordDate]>=O5,IF(Weartime13[RecordDate]<=J5,IF(Weartime13[SignUpRole]=L9,MATCH(Weartime13[UserId],Weartime13[UserId],0)))),ROW(Weartime13[UserId])-ROW(A5)+1),1))
and in the next column that would change to M9 and N9:
=SUM(IF(FREQUENCY(IF(Weartime13[RecordDate]>=O5,IF(Weartime13[RecordDate]<=J5,IF(Weartime13[SignUpRole]=M9,MATCH(Weartime13[UserId],Weartime13[UserId],0)))),ROW(Weartime13[UserId])-ROW(A5)+1),1))
=SUM(IF(FREQUENCY(IF(Weartime13[RecordDate]>=O5,IF(Weartime13[RecordDate]<=J5,IF(Weartime13[SignUpRole]=N9,MATCH(Weartime13[UserId],Weartime13[UserId],0)))),ROW(Weartime13[UserId])-ROW(A5)+1),1))
I've filled in the last row:
EDIT
As noted by #JosWoolley, a structured reference would have been preferable to row(A5). I would suggest:
=SUM(IF(FREQUENCY(IF(Weartime13[RecordDate]>=O5,IF(Weartime13[RecordDate]<=J5,IF(Weartime13[SignUpRole]=L9,MATCH(Weartime13[UserId],Weartime13[UserId],0)))),ROW(Weartime13[UserId])-ROW(Weartime13[#Headers])),1))
But what if you want to pull these formulas across so that L9 changes automatically to M9 and N9 but it still references the same table columns? I had to look this one up and the answer is:
=SUM(IF(FREQUENCY(IF(Weartime13[[RecordDate]:[RecordDate]]>=$O5,IF(Weartime13[[RecordDate]:[RecordDate]]<=$J5,IF(Weartime13[[SignUpRole]:[SignUpRole]]=L9,MATCH(Weartime13[[UserId]:[UserId]],Weartime13[[UserId]:[UserId]],0)))),ROW(Weartime13[[UserId]:[UserId]])-ROW(Weartime13[#Headers])),1))
Formula for the last row using count & filter would be
=COUNT(UNIQUE(FILTER(Weartime13[UserId],(Weartime13[RecordDate]<=J5)*(Weartime13[RecordDate]>=O5))))
for the total and
=COUNT(UNIQUE(FILTER(Weartime13[[UserId]:[UserId]],(Weartime13[[RecordDate]:[RecordDate]]<=$J5)*(Weartime13[[RecordDate]:[RecordDate]]>=$O5)*(Weartime13[[SignUpRole]:[SignUpRole]]=L9))))
pulled across for the SignUpRole breakdown, assuming UserId is numeric.
But what if you wanted a single formula that could be pulled both down and across for the whole range of dates and roles? This could be arranged as follows:
=COUNT(UNIQUE(FILTER(Weartime13[UserId],(Weartime13[RecordDate]<=J$5)*(Weartime13[RecordDate]>=INDEX($K$5:$O$5,ROW()-ROW($9:$9))))))
for the total and
=COUNT(UNIQUE(FILTER(Weartime13[[UserId]:[UserId]],(Weartime13[[RecordDate]:[RecordDate]]<=$J$5)*(Weartime13[[RecordDate]:[RecordDate]]>=INDEX($K$5:$O$5,ROW()-ROW($9:$9)))*(Weartime13[[SignUpRole]:[SignUpRole]]=L$9))))
for the role columns.
Is there a simpler way of doing this whole thing? Maybe with pivot tables or perhaps power query, but that would be a separate answer :-)

How to count unique column data in an excel sheet

I am using excel sheet and i have data column as shown below:
As we can see that some of the names are duplicate or appeared twice. My question is how can count unique name records or rows associated with each name for summary column.
Out put i am looking for is shown below:
Not sure which formula to use as count is counting all of that data i.e. '7' in this case. How can i use count or any other function to count unique records as shown above?
You can do what you're after with a pivot table.
Click the Insert tab then select "Recommended Pivot Tables".
A window will open up prompting you to select the data range. I recommend using a named range for your list and referencing that, but you can just highlight the list directly if you want.
Once the data range is selected, click "Ok" and new window will open with exactly what you want. A unique values list and a "Count of Column1". It is the default of the recommended pivot tables.
I outlined this because it's easy and fast, but it's important to understand you can make this pivot table yourself from scratch if you learn about pivot tables in general. Pivot tables are often overlooked in Excel as an option.
Lastly, you could get really advanced with Excel Power Queries. Just Google "Excel Power query" and you will be shown all kinds of information on them. They are a close second place in power to manipulate Excel data short of using VBA.
Good luck!
CountA(Unique(D2:D8,,False)) = 5 [Count(Unique(D2:D8)) is the same as False is the default.]
CountA(Unique(D2:D8,,True)) = 3 (once and only once)
Note: the Unique function was released in late 2019 to Office 365. So if you want to use this check your version, not present in 1908, present in 2006.
Edit: It's actually in 2002, I just updated my 1908 machine.

If names duplicates are removed the following formula can be used: =COUNTIF(B:B,F2)
If duplicates must be removed by formula, MATCH (searches for a specified item in a range of cells, and then returns the relative position of that item in the range.) and SMALL (Returns the k-th smallest value in a data set.) functions can be used as shown.
C$1048576 is used to reference last row number for a big list case.
formulas:
Column A, names sequence
Colunm B, names
Column C, formula =MATCH(B2,B:B,0)
Column D, formula =IF(COUNTIF(C2:$C$1048576,C2)=1,C2,"")
Column E, formula =SMALL(D:D,A2)
Column F, formula =VLOOKUP(E2,A:B,2,0)
Column G, formula =COUNTIF(B:B,F2)
For anyone like me without O265's lovely Unique & Filter Functions, and who doesnt want to use a pivot table, and there are many ways to do this, but this i have just done this in normal excel.
List of data in Column H, Formula in column O3. Drag down. Highlights your distinct and unique values from H.
=IF(COUNTIF(H:H,H28)=1,"U - "&COUNTIF(H:H,H28),IF(COUNTIF(H$1:H27,H28)=1,"U - "&COUNTIF(H:H,H28),"-"))
Formula is short. You can just do this and drag down. Apply the same principal to your worksheet data wherever it is.
=IF(COUNTIF(H:H,H3)=1,"U",IF(COUNTIF(H$1:H2,H3)=1,"U","-"))
Similarly, you can just use this formula here (credit goes to this source for this one):
=(COUNTIF($H$1:$H1,$H1)=1)+0
Id like to point out that the above formula is a better formula than mine. It highlights with a "1" (or with a tweak, the value of your choice) the first time any value is seen/spotted on any given list, whether duplicate or unique.
Whereas mine is a bit "more random" when picking up the "unique and distict" values.
Mine gets there in the end, but Extend Office's gets there first, as I think is proper (getting the first time a unqique distict value is spotted/occurs.).
Formula in K5 =IF((COUNTIF($H$5:$H5,$H5)=1)+0=1,"UNIQUE DIST","") and drag down...
You could append/add a normal basic countif after the results to show how many actual times the given value appears if you wanted. :
=IF((COUNTIF($H$5:$H5,$H5)=1)+0=1,"UNIQUE DIST","")&" - "&COUNTIF(H:H,H5)

Excel - Get unique count based on multiple columns (including date)

I'm trying to get a unique count of data in Column B that fall into the month of June (Column A date field)
Screenshot of Spreadsheet
I highlighted the rows that fall within June in Orange and the duplicate data in red to make it easier to view.
Count Total formula is a simple:
=COUNTA(A:A)-1
Unique Data formula is:
=SUMPRODUCT(1/COUNTIF(B2:B21,B2:B21))
Count June formula is:
=COUNTIFS(A:A,">=01/06/2020",A:A,"<30/6/2020")
But I can't figure out how get a count of unique data that falls within June (expected result is 13)
I've tried filter/unique formulas based on
Excel - Count unique values that meets multiple criteria
But I just can't get it to work. I know I could do it with VBA but this is part of a larger spreadsheet and every other part of the spreadsheet I've been able to do with Formulas, so would like to be able to do this last part with formulas too.
Anyone can help will be a life saver, it's been driving me nuts for the last couple hours.
In Excel 2016, which does not have the UNIQUE or FILTER functions, you can use this somewhat convoluted formula for a Unique count of June entries:
=SUM(IF(FREQUENCY(IF(LEN(IF(MONTH(Table1[Date])=6,Table1[Data],""))>0,MATCH(IF(MONTH(Table1[Date])=6,Table1[Data],""),IF(MONTH(Table1[Date])=6,Table1[Data],""),0),""),IF(LEN(IF(MONTH(Table1[Date])=6,Table1[Data],""))>0,MATCH(IF(MONTH(Table1[Date])=6,Table1[Data],""),IF(MONTH(Table1[Date])=6,Table1[Data],""),0),""))>0,1))
This part of the formula: IF(MONTH(Table1[Date])=6,Table1[Data],"") returns an array consisting of all of the June Data entries.
The LEN(... eliminates the resultant blanks
The Frequency function will then have us wind up with a count of 1 for each entry.
Then we just add it up.
Note that I used a Table and structured references, but you can convert it to regular addressing if you need to.
Of course, if you had Excel O365, you could use the simpler:
=COUNTA(UNIQUE(FILTER(Table1[Data],MONTH(Table1[Date])=6)))

Find and Compare Two Columns Excel (With Screenshots)

I have a spreadsheet that will occasionally get new data that I don't know the contents of, I just have to add it to the spreadsheet. Some of the new data is just updating rows that are already in the spreadsheet, and other data is adding new rows. I'm looking for a way to add a column that will tell me if something has changed in the row when I compare the old spreadsheet to the new one.
The sheets have one column that will always have a unique value among all the rows, so I can use that to match rows if the sheets aren't sorted the same way. Here are some screenshots to show what I'm trying to do:
Old Spreadsheet:
New Spreadsheet:
The only solution I can think of is a large nested IF formula that compares each column one by one, something like:
=IF(Old!B2=New!B2,IF(Old!C2=New!C2,"NO","YES"),"YES")
The problem with that is that it gets very hard to look at since my actual data is using 33 columns (not including this "Changed?" column) and new columns could be added in the future.
I'm not very technical with Excel, nor have I ever used VBA, so I apologize in advance if there is a simple/obvious solution that I'm missing.
Thanks in advance for your help.
Using your example, in the 'New' sheet cell D2 and copied down:
=IF(COUNTIF(Old!A:A,A2)=0,"YES",IF(SUMPRODUCT(COUNTIF(INDEX(Old!A:AG,MATCH(A2,Old!A:A,0),0),LEFT(A2:AG2,254)&"*"))=SUMPRODUCT(COUNTIF(A2:AG2,LEFT(A2:AG2,254)&"*")),"NO","YES"))
vlookup would also work well for this problem.
in D2, the formula would be:
=IF(AND(VLOOKUP(A2,Old!A:C,2,FALSE)=B2,VLOOKUP(A2,Old!A:C,3,FALSE)=C2),"NO","YES")
The column numbers (2 and 3) are the columns that correspond to the data you are trying to match, using the ID column.
It's possible to find the appropriate column using MATCH if the column names you have match the column names in the old sheet
This would make the formula look more complex, but Excel would adjust the Old!A:C reference if more columns are inserted.
The formula would look like this to match against column names
=IF(AND(VLOOKUP(A2,Old!A:C,MATCH($B$1,Old!$1:$1,0),FALSE)=B2,VLOOKUP(A2,Old!A:C,MATCH($C$1,Old!$1:$1,0),FALSE)=C2),"NO","YES")
The difference between this and the last one is the use of MATCH($B$1,Old!$1:$1,0) to find the column (using $s to anchor the lookup values)
In this case, specialized software for Excel compare is better.
My company use this software. Check it out.

Excel VLOOKUP #REF Error

I'm trying to create an integrated athletic planning and training calendar. Part of this is for one sheet to identify weeks in which races occur based upon races and dates identified by the user on another sheet. I've confirmed that my VLOOKUP is not referencing a non-existent column and that the cell style is General for those applicable.
Here is the formula:
=VLOOKUP(Periods!A6,Races!$F$2:$F$20,2,FALSE)
The Lookup Value is the Training week on the first image and is used to identify races on the target worksheet. Each row on that sheet has a different training week. I am trying to get Column D (and F) on the formula sheet to show the priority of the race if there is one planned for the applicable week.
Any help is appreciated.
Thanks!
Mike
the ,2, in your vlookup here =VLOOKUP(Periods!A6,Races!$F$2:$F$20,2,FALSE) means go to the right of column F2:F20 if a match is found in column F, but, you need to specify F2:G20 for that to work in your vlookup formula. (which still won't give you the results you are expecting)
You have two options,
Option 1: reorganize your target worksheet so your lookup value is on the left, so you can use vlookup to pull columns to the right of it
Option 2, use a different kind of formula like a Match + index combination. (untested, but example below)
=Index(Races!$B$2:$B$20,match(Periods!A6,Races!$F$2:$F$20,0))
