## Filter emails spread over several columns in excel

*Article last updated on July 23, 2017*

**magneticone asks:**

Any idea how to adapt the formula to do a conditional (i.e. comma-separated) merge of the data from multiple columns, in the case that a single row has emails spread over several columns?

**Answer:**

**Array formula in E2:**

Copycell E2 and paste it down as far as needed.

Every cell containing "@" is **filtered **into column E.

Wowowow.... that's why you're the best!

I was just thinking when reviewing this awesome update to the previous email extract formula, could we add a placeholder column at E which gets updated dynamically. Then, instead of listing the emails down the length of that column, we could just add each multiple emails immediately to the right column. So columns F,G,H (or however many data columns we have worth) would hold the data in any cell which contains an email... and E would also just be a merge of those (which we could apply the VBA comma-separated filter and multi-email extraction code from the first example).

So the current table would become:

Where E is a comma-separated list of email-containing columns, and the empty D column would become our final list of emails only.

Hard to say exactly where to make these changes since there's so much going on in that formula, but for starters I think I'd need to switch the references to ROW()+1 into COLUMN()+1?

P.S> What is the role of the magic number 1048576?

magneticone,

I modified Rick Rothsteins ConCat udf.

Function ConCat(Delimiter As Variant, ParamArray CellRanges() As Variant) As String

Dim Cell As Range, Area As Variant

If IsMissing(Delimiter) Then Delimiter = ""

For Each Area In CellRanges

If TypeName(Area) = "Range" Then

For Each Cell In Area

If Len(Cell.Value) And InStr(Cell.Value, "@") Then ConCat = ConCat & Delimiter & Cell.Value

Next

Else

ConCat = ConCat & Delimiter & Area

End If

Next

ConCat = Mid(ConCat, Len(Delimiter) + 1)

End Function

How to implement user defined function in excel

1. Press Alt-F11 to open visual basic editor

2. Click Module on the Insert menu

3. Copy and paste the above user defined function

4. Exit visual basic editor

5. Select a cell

7. Type =ConCat(", ", A1:D4) into formula bar and press ENTER

Your formula above works only if the range you are querying begins in column A. A modified version which works with ranges that don't start in the 1st column is here:

=INDEX($A$1:$C$3, SMALL(IF(ISNUMBER(SEARCH("@", $A$1:$C$3)), ROW($A$1:$C$3)-MIN(ROW($A$1:$C$3))+1, ""), ROW(A1)), (SMALL(IF(ISNUMBER(SEARCH("@", $A$1:$C$3)), (ROW($A$1:$C$3)-MIN(ROW($A$1:$C$3))+1)+(COLUMN($A$1:$C$3)-MIN(COLUMN($A$1:$C$3))+1)/1048576, ""), ROW(A1))-SMALL(IF(ISNUMBER(SEARCH("@", $A$1:$C$3)), ROW($A$1:$C$3)-MIN(ROW($A$1:$C$3))+1), ROW(A1)))*1048576)

Jon,

You are right! Thanks for your contribution!
