VBA - Eliminate duplicate numbers in a column and leave original only

[skyport]

What is needed here on this one is assuming column A will contain a list of telephone numbers entered in this format: (xxx) yyy-zzzz which is how it would appear in the formula bar if the cell were selected, a macro that would eliminate all duplicates but the most important aspect would be to always retain the first entry of the number in column A and only eliminate any and all subsequent duplicate entries of same numbers.

the final twist if possible, although not critical, would be to show in column C those duplicate numbers that were eliminated from column A when the Macro runs.

Sir Dexter - brilliant - I didn't know that function (but I only have excel 2000)

 

[skyport]

Good morning Oldbrewer and sirDextor, Thank you both for helping. Here is what I am running into with each one and please note I am using Excel 2000 as well.

With Oldbrewer's code, it does't seem to to show in the selection of macros to use when ALT F8 is used after it has been inserted in a new module from ALT F11. Therefore I am unable to even test it yet.

With sirDextor's code, it does show up in the menu window from ALT F8 however when I run it I am getting the following error message:

run-time error 438 Object doesn't support this property or method

Any suggestions would be greatly appreciated.

 

[oldbrewer]

how i write a macro

tools, record new macro, click on cell A1, stop macro

tools, macro, edit, delete the single line of code that selected A1 and type in your macro (or copy it in)

go back to spreadsheet and run it

debug as necessary

 

[skyport]

Got it. Thanks again for helping
