Struggling with duplicate data in Excel? Discover four innovative methods to identify and eliminate duplicates, whether in columns, rows, or across your entire dataset.
⬇️ Download the file I use in the video from here: pages.xelplus.com/find-duplic...
What You'll Learn:
▪️ Column Comparison: Easily spot overlapping data between two columns.
▪️ Row-Wise Duplication Check: Identify entire rows that are duplicates.
▪️ Formula-Based Duplication Detection: Utilize Excel formulas for dynamic duplicate flagging.
▪️ FILTER Function for Duplicates: Extract only duplicate rows for a clearer view of your data.
In this video I'll show you 4 ways on how to find duplicates in your Microsoft Excel data. We'll find solutions regardless if your data is in the same column, in separate columns and even if you need to find duplicates for a combination of cells. You'll learn how to use conditional formatting to color duplicate values, how to look inside an entire row and compare one row with another and flag it is a duplicate. As a bonus you'll learn how to use a dynamic formula to flag duplicate entries with an icon or returns just the duplicate entries.

how about if you need to compare from two different excel files?
She is hands down the best person for excel problems. It's the way she explains it. Let's face it, when you come to her videos, you usually have a problem, and you're usually on a deadline. She gets right to it.
This showed on my feed at the perfect time. I'm going to be applying your last example to a data set with around ~10,000 rows today. This will make it so much easier that what I normally do. Thanks!
It never came to my mind to add emojis in cells! That's really cool and opens up many possibilities to make the sheet more appealing 😊
'Thursday's with Leila' just doesn't disappoint ... even when not immediately useful, the videos still plant ideas for future harvest ... 🌱🌿🌿🌱🌱 At the 8:20 mark " ...

ahhh thank you for the two thumbs up. Appreciate it.
Great video.... be careful when combining columns when looking for duplicates. I recommend putting a delimiter between the columns to help eliminate false duplicates. If you have the values AA BB two columns of data in the first row, and A ABB as the second row, they will end up giving you a false duplicate of AABB. Use a "-" as a delimiter to help remove this possibility. AA-BB won't get confused with A-ABB.

That's true!
I know this is a little off topic, but for anyone removing duplicates in power query for excel or power bi, there is a trap. Yes, just like in an excel spreadsheet the first unique row found is retained while others are removed. However, the way that first row is defined is the trap. It is not defined as the first row as the data is currently, but the first row when the data was first loaded. So you might do a sort to ensure the rows you want retained are at the top then remove duplicates but this will not give you the correct result. The solution is to include Table.Buffer in the remove duplicate query to reset the state of the data to the current sort order. Then the power query remove duplicates operation will work the same as if you removed duplicates from an excel spreadsheet.

Thanks Leila for the video and for always keeping us abreast with excel advancements. Wondering if there's a formula for highlighting figures that 'knock off each other' in a column. Let's say 12 and -12 or -1,000 and 1,000? Thanks

Its a Discovery.. Thank You for the Valuable Information. I Have Been Using CountIf with start cell as Absolete and 2nd Cell as Relative in a Range. A1:A100 Has Unique and Duplicate Values Formula For B2 =CountIF($A$2:$A2,$A2) Formula For B3 =CountIF($A$2:$A3,$A3) Formula For B4 =CountIF($A$2:$A4,$A4)
As always, you made my live much easier! Thank you Leila ❤

Thank you for your useful conclusion~ same, I'd like to share another quick way to find duplicates with you, and hope it can be helpful too! you just need to open your file in WPS Office> select the range of your values>click “highlight duplicates”> click “set” then all the dupplicates will appear!
We can simply use 'Countifs' instead of 'Countif' + Concatenate to integrate multiple columns while finding duplicates..Great video as always 👍

In the last exercise to pull out just the duplicates, an alternative is to use UNIQUE instead of SORT in case you don't want to see the same record multiple times over.
Thanks Leila for those tips!

I thought you will show how to do it without additional column. I created this solution: =COUNTA(FILTER($A$1:$B$7,($A$1:$A$7=A1)*($B$1:$B$7=B1)))>2 It creates range of duplicated values equal to current row. If there are more than 2 elements (assuming we have 2 columns) it means that there is at least one more duplicated row. I hope someone will find it helpful.

How to retain original value without colouring?
Perfect 👍
thank you and God bless :)
Nice work. This might be helpful. I used to get very odd behaviour using COUNTIF embedded in a lambda function that was called from within another LAMBDA (something to do with it not accepting the variable which although was a vector, was strictly not a RANGE, which it must take as its first argument). It did my head in! This formula avoids using COUNTIF, and IMO is more robust (when doing complex and nested lambdas) . Hope its useful COLUMN_DUPLICATES = LAMBDA(col_vector, LET( count, SCAN(0, col_vector, LAMBDA(a, r, SUM(--(r = col_vector)))), duplicates, IF( IFERROR(ROWS(UNIQUE(FILTER(col_vector, count > 1))), 0) = 0, "No Duplicates", UNIQUE(FILTER(col_vector, count > 1)) ), duplicates ) );
Wow!!!!!! Brilliant
Amazing stuff. Thank you, Leila! I have been trying to find a way to make a unique list of values across multiple columns (Let's say A has people who have bought product 1, B has people who bought product 2 and I want the full list of customers). Any ideas, guys? Do we have a better way to do it than copying one list, going to the end of the other and pasting it, then using unique?
