Count continuous duplicates
I'm trying write a formula to count the duplicates in a column where they
appear contiguously (adjacent to one another). Another way of putting this is to count the number of times a number appears continuously in a column before it changes to another number. I have Excel 2007. Example: ColumnA ColumnB ColumnC(answer) 0001 30 2 0001 30 0001 70 1 0001 30 2 0001 30 Your help is greatly appreciated |

C1: =MATCH(9.99999999999999E+307,B:B) C2, confirmed with CONTROL+SHIFT+ENTER, and copied down: =IF(B2<B1,COUNTIF(B2:INDEX(B2:INDEX(B:B,$C$1),LOO KUP(9.99999999999999E+3 07,CHOOSE({1,2},$C$1-ROW(B2)+1,MATCH(TRUE,B2:INDEX(B:B,$C$1)<B2,0)))), B2 ),"") -- Domenic Microsoft Excel MVP www.xl-central.com Your Quick Reference to Excel Solutions |
Count continuous duplicates
Hi,
Try this array formula (Ctrl+Shift+Enter) in cell C5 and copy down. I have assumed that the numbers are in range B5:B9. Please ensure that you leave a couple of blank rows below the table blank =IF(B5=B4,"",MATCH(FALSE,($B6:$B9=B5),0)) -- Regards, Ashish Mathur Microsoft Excel MVP www.ashishmathur.com "Excel Curious" wrote in message ...
