## Merge three columns into one list

The above image demonstrates a formula that adds values in three different columns into one column.

Formula in H2:

Copy cell H2 and paste to cells below.

### Explaining formula in cell H2

The IFERROR function moves the calculation to the next part (formula2) when the first part (formula1) begins to return errors. That is also true for the second part (formula2), when errors occur the calculation continues with the third part (formula3)

IFERROR(IFERROR(*formula1*, *formula2*), *formula3*)

Formula1 extracts values from List1. Formula2 extracts values from List2. Formula3 extracts values from List3.

#### Step 1 - Count cells vertically

The ROWS function counts rows in a cell reference. H2:$H$2 is special, it expands as the formula is copied to cells below.

ROWS(H2:$H$2)

returns 1.

#### Step 2 - Return value

The INDEX function returns values from a cell range based on a row number and column number.

INDEX($B$3:$B$7, ROWS(H2:$H$2))

becomes

INDEX($B$3:$B$7, 1)

becomes

INDEX({"AA";"DD";"CC";"GG";"HH"}, 1)

and returns "AA" in cell H3.

#### Step 3 - Loop

When the formula starts returning errors the second part of the formula begins.

INDEX($D$3:$D$4, ROWS(H2:$H$2)-ROWS($B$3:$B$7))

It also takes into account the number of values returned from the first cell range, for example in cell H8:

INDEX($D$3:$D$4, ROWS(H7:$H$2)-ROWS($B$3:$B$7))

becomes

INDEX($D$3:$D$4, 6-ROWS($B$3:$B$7))

becomes

INDEX($D$3:$D$4, 6-5)

becomes

INDEX({"MM";"WW"}, 1)

and returns "MM" in cell H8.

### Excel 2003 and earlier versions:

**Named ranges**

List1 (A2:A6)

List2 (B2:B3)

List3 (C2:C5)

Thanks A LOT!!! I really mean it. Lifesavers you guys are!

Can you translate this into an earlier version of Excel please....I REALLY wish I had a clue how to use VBA (or how to write these formulas myself!)

Shawna,

Yes, the formula is large but it is not an array formula. I have included the excel 2003 solution in this blog post. Read above and you can also get an Excel 2003 file.

Thanks, now we're cooking!! Anyway to remove the blanks from the resulting "merged" list?

nevermind...sorry I bothered you, I can't get the new formula to work at all, so it's pointless. Thanks for the time and effort anyway.

Hmmm, tried again and I got it to work, but I still come up with zeros if one of my Lists has a blank. This is SO frustrating!!

Shawna,

I hope this user defined function works in excel 2003:

Where to copy the code?Press Alt-F11 to open visual basic editor

Press with left mouse button on Module on the Insert menu

Copy and paste the user defined function into module

Exit visual basic editor

How to use user defined function in excelSelect a cell

Type MergeRanges(A1:C10, Sheet2!A3:B10) in formula bar, you can have as many range arguments you like.

Press Ctrl + SHIFT + ENTER

Add more cells to your selection.

Press with left mouse button in Formula bar.

Press Ctrl + SHIFT + ENTER

I wish I could try it, but I don't know how to create VBA. I'm a novice, though I did try a few times from random directions online, but it didn't work. :(

LOL, sorry...you gave me directions to follow, DUH! It's early, I'm not awake yet, so the attention hasn't kicked in. I'll let you know how I make out when I get to work. Thanks!

Nope...I set up the following example:

Heading1 Heading2 Heading3 Merge aa aa bb hh bb

cc ii 1 cc

2 dd

dd jj 3 dd

ee ee

kk 4 ff

ff ff

gg gg

#VALUE!

#VALUE!

#VALUE!

I pasted the code in the VBA module and typed the statement:

=MergeRanges(A2:A11, B2:B11, C2:C11) into the Merge cell. Then copied it down. However, notice only the A range merged. Also, the merged column repeated dd and ff (the only ones preceeded by a space). Any idea what I messed up?

Shawna,

Get the Excel file

udf-merge-ranges.xls

Udf is in cell range B3:B24, sheet1.

Can we please discuss via email so I can attach an example of what I am doing? My typed example above was obviously worthless! LOL

Thanks! :)

Hello,

I gotr your Excel workbook and wanted to know how to combine lists that are 2000 items in length?

Hi Oscar,

Here I found one interesting solution to merge table to single row. It could be useful for you :)

https://www.cpearson.com/excel/TableToColumn.aspx

I modified formula with INDEX() function (array formula) and like result :)

=INDEX(Table;1+MOD(ROW()-ROW(MergedRange);ROWS(Table));1+TRUNC((ROW()-ROW(MergedRange))/ROWS(Table);0))

Best regards

The solution is to merge table to single column, not row...

BatTodor,

Thanks for sharing!

Brilliant work, I converted List1, List2,List3 into dynamic range.

ALIST = =OFFSET($A$1,0,0,COUNTA($A:$A),1)

BLIST = =OFFSET($B$1,0,0,COUNTA($B:$B),1)

CLIST = =OFFSET($C$1,0,0,COUNTA($C:$C),1)

DLIST = =OFFSET($D$1,0,0,COUNTA($D:$D),1)

Here link to solution with screenshot.

Zuberr,

thank you!

This is a very useful formula. But, here the list names have fixed ranges and if the ranges expand or reduces, then the formula does not hold good. For example, list1 range A1:A20 with data upto A7, list2 range B1:B20 with data upto row b17 and list3 range C1:C20 with data upto C10. In simple words, the ranges need to be dynamic. Can anybody help with a formula (not Vba). Regards.

R Vijayakumar,

Try this:

https://www.get-digital-help.com/2011/05/17/excel-charts-use-dynamic-ranges-to-add-new-values-to-both-chart-and-drop-down-list/

i have tried in different ways and found this array formula works....

=IFERROR(IFERROR(IFERROR(INDEX(MultiPlyYarnPRCount, MATCH(0, COUNTIF(L$7:$L7, MultiPlyYarnPRCount), 0)), INDEX(MultiPlyYarnDHPRCount, MATCH(0, COUNTIF(L$7:$L7, MultiPlyYarnDHPRCount), 0))),INDEX(MultiPlyYarnDHCRCount, MATCH(0, COUNTIF(L$7:$L7, MultiPlyYarnDHCRCount),0))),"")

MultiPlyYarnPRCount (I8:I100),MultiPlyYarnDHPRCount (J8:J100) and MultiPlyYarnDHCRCount (K8:K100) are three ranges in three columns, each having varying lengths of data i.e. first range has data in only one row, second range 23 rows and third one has 18 rows of data. This formula works fine.

I request your suggestion for fine-tuning the formula if possible.

Regards,

I really need help!

Have similar but bigger issue

Have three columns in excel:

Column A: Category

Column B: Value

Column C: Value

I want to consolidate the list such that if I have a row like:

A1=Car | B1=Ford | C1=Toyota

A2=Scooter | B1=Honda | C1=(blank)

Gives me a result:

A1=Car | B1=Ford

A2=Car | B2=Toyota

A3=Scooter | A3=Honda

Sorry, correction:

A2=Scooter | B2=Honda | C2=(blank)

A1=Car | B1=Ford

A2=Car | B2=Toyota

A3=Scooter | B3=Honda

How can I merge 5 columns?

thanks

The easiest way to go is to use a simple user defined function:

Hi people,

Here's a solution i'm trying to solve using the functionality/formula provided at the top of this post .

Let's substitute List1, List 2 and List3 ranges with dynamic ranges that are using offsets when referring to data filter results elsewhere in my workbook. these dynamic ranges sometimes return no data as there are no results at times in my filters . my problem is, when one of the dynamic ranges has no data in it, that then corrupts the merge.

My mind is thinking incorporating ISBLANK or something similar to the above IFERROR INDEX ROWS formula where an empty dynamic range doesn't then corrupt the merge.

Hope that makes sense. Am drowning in development deadlines, any help would be much appreciated.

Hi Geoff

Have you read this article?

https://www.get-digital-help.com/2010/05/18/merge-two-columns-with-possible-blank-cells-in-excel-formula/

I've been looking at this article as well as the article on "Merge two columns with possible blank cells", but I'm trying to find out how to do a union of the two:

How do I merge multiple (3+) columns into one, where there are blank or #N/A cells involved?

I can use the Two-Into-One article just fine for handling blanks (or changing isblank to isna to handle #N/A values), but I haven't been able to get it to handle 3+ columns even after trying to combine the parsing of both articles together.
