Change Sheet name in the formula

[darkarahat]

This formula for find duplicate in multiple sheets but i have a problem when changed the name of sheets
=$A$2:$A$1000000
=SUM(COUNTIF(INDIRECT("'Sheet" & ROW($1:$4) & "'!$A:$A"),$A2))>1

That rule i apply on the Home ---> Conditional Formatting ---> New Rule

The problem is when i change sheets name from Sheet1 to Jan, Sheet2 to Feb and so on, the formula not working. I try to changes "'Sheet" to "Jan" or "'Jan" but still not working

Please help me for your advice, thank you

See if this works:

=SUM(COUNTIF(INDIRECT(TEXT(DATE(1900,ROWS($A$1:A1),1),"mmm")&"!$A:$A"),$A2))>1

In sheet called 'Jan' place 999 in cell A1. What does this produce:

=INDIRECT(TEXT(DATE(1900,ROWS($A$1:A1),1),"mmm")&"!A1")

Ok make your Sheets called Jan, Feb, Mar, Apr then

=SUM(COUNTIF(INDIRECT(TEXT(DATE(1900,ROW(A1:A4),1),"mmm")&"!$A:$A"),$A2))>1

Missed some absolution of the cells:

=SUM(COUNTIF(INDIRECT(TEXT(DATE(1900,ROW($A$1:$A$4),1),"mmm")&"!$A:$A"),$A2))>1
