formula to sort and delete duplicates

[jococourthouse]

Hello,

I am looking for a way to sort and delete duplicates.

example below

[TABLE="class: grid, width: 500, align: center"]
<tbody>[TR]
[TD]number[/TD]
[TD]sorted and delete duplicates[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]1[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]2[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]3[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]4[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
</tbody>[/TABLE]
The column labeled number needs to be left the same.

Thanks for any help!

Welcome to the Board!

Depending on your needs, it might be easiest to use some of the built-in functions of Excel. Use copy/paste to copy column A to column B, then use the Remove Duplicates tool from the Data tab, then use the Sort tool. Once you get the hang of it, you can do it in a few seconds. This could be automated by VBA if you want.

You could also use a formula to do that. For example:

Excel 2012

	A	B
number	sorted and delete duplicates

<colgroup><col style="width: 25pxpx"><col><col></colgroup><thead>
</thead><tbody>
[TD="align: center"]1[/TD]

[TD="align: center"]2[/TD]
[TD="align: right"]1[/TD]
[TD="align: right"]1[/TD]

[TD="align: center"]3[/TD]
[TD="align: right"]2[/TD]
[TD="align: right"]2[/TD]

[TD="align: center"]4[/TD]
[TD="align: right"]3[/TD]
[TD="align: right"]3[/TD]

[TD="align: center"]5[/TD]
[TD="align: right"]1[/TD]
[TD="align: right"]4[/TD]

[TD="align: center"]6[/TD]
[TD="align: right"]2[/TD]

[TD="align: center"]7[/TD]
[TD="align: right"]4[/TD]

[TD="align: center"]8[/TD]
[TD="align: right"]4[/TD]
[TD="align: right"][/TD]

[TD="align: center"]9[/TD]
[TD="align: right"]4[/TD]
[TD="align: right"][/TD]

[TD="align: center"]10[/TD]
[TD="align: right"]2[/TD]
[TD="align: right"][/TD]

[TD="align: center"]11[/TD]
[TD="align: right"][/TD]
[TD="align: right"][/TD]

</tbody>

Sheet1​

[TABLE="width: 85%"]

[TD="align: left"]{=IFERROR(INDEX($A$2:$A$10,MATCH(0,COUNTIF($A$2:$A$10,"<"&$A$2:$A$10)-SUM(COUNTIF($A$2:$A$10,$B$1:$B1)),0)),"")}[/TD]
[/TR]

Entered with Ctrl+Shift+Enter. If entered correctly, Excel will surround with curly braces {}.
Note: Do not try and enter the {} manually yourself[/TD]

Hope this helps!
