given 2 lists of words
1. Select column B (click the letter B)
2. Choose Format > Conditional formatting
" 3. In ""Condition 1"" choose ""Formula is"""
" 4. Enter this formula =(COUNTIF($A:$A,B1)=0)*(B1<>"")"
" 5. Click the ""Formats"" button and take your pick. OK.OK."
Now every name in B not in A will light up.
Another example
comparison of 2 columns
=IF(ISERROR(VLOOKUP(A1,$B$1:$B$2000,1,FALSE)),A1,"")
this function put in c1 and autofilled down will show the A1 value,
IF A1 does not exist anywhere in B1:B2000 -
3rd example...
Reply to: Compare two columns using wildcards
=ISNUMBER(MATCH(LEFT(A1,9)&"*",List2!A:A,0))+0
where A1 is a value from the 1st column and List2!A:A is
a reference to your 2nd column. This formula will return
0 or 1. 1 means that there's a match; 0 means there isn't.
You can apply a number format to change these values to any
flag you wish. For example, [=1][green]"Y";[red]"N" will
produce a green "Y" or a red "N".
------ Unique Rows Selection ----------
Has anyone done a macro that will retain the compare values in a column
and will retain
the first of each unigue entry and delete the rows with repetitive data?
Answer 1
If you don't require a macro, you could highlight your social security
row and goto data,
filter, advance filter. Check unique records only and okay. Note - dumps
unique records,
not unique cells.
Highlight the collapsed list. Hit control G, special, visable cells only
and control c
to copy. Then control V to paste your list on a new sheet with no
duplicates.
If you tell the advanced filter to put the results in a different column
(rather than
filtering the list in place) you can skip the copy paste as values
steps.
.. . . For a single column . . . . . . .
You can mark the duplicates, filter the list to display the marked
entries, and delete
the visible rows.
1. Mark the duplicates. See Tagging Duplicate Entries at:
http://www.cpearson.com/excel/duplicat.htm
2. Apply a filter, using Filter>AutoFilter
3. Select the visible rows
4. Choose Edit>Delete
* * * * * * * * * * * * * * * * *
:::Steps to remove duplicates:
Use Chip's technique to tag the duplicates. Then, turn on AutoFilter
(Data>Filter>AutoFilter). From the drop-down list in the Tag column,
select "Duplicate". Select the rows that remain visible, and delete
them.
