Highlight changed values week on week basis

[vaibhav tandon]

I am trying to compare to sets of data pulled from tool to highlight the changes that Project Managers have made week on week basis as compared to last week. Tab 'old' has last week data while tab 'New' has data. I used formula in conditional formatting "=A1<>Old!A1" but this is only limited if both sheets have the data arranged in same manner. But since there are new projects added each week there is reordering of projects and gives me wrongly highlighted cells.


For example E got added this week in 'new' tab and comparing it with row 5 of 'old' tab and giving wrong highlighted cells.

The longer method i could think of is to rearrange all the data and apply the same formula however due to time contraints its not viable since the data lines are almost 10000.

Could any one suggest a better way of highlighting the changed cells?

Thanks @oldbrewer for the prompt response and help, however I am not able to build that into conditional formatting + I also want to highlight all the cells that changed instead of one. any further help would be appreciated.

Thanks a lot!

 

[oldbrewer]

once you have the correct conditional formatting in one cell, you use format painter to apply it to all the desired cells.

when you say you are not able to build that into conditional formatting, is that because you have tried and failed ?

=IF(ISERROR(OFFSET($A$1,MATCH(I20,$A$2:$A$7,0),1)),"new",IF(OFFSET($A$1,MATCH(I20,$A$2:$A$7,0),1)=J20,"same","changed"))

the first part does not find a match so it is a new project
the second part checks if the colors are the same

so because we do not know if it is a new project or not we use an and statement

something along the lines....

=and(ISERROR(OFFSET($A$1,MATCH(I20,$A$2:$A$7,0),1))=FALSE, OFFSET($A$1,MATCH(I20,$A$2:$A$7,0),1)=J20)))

so if it is not a new project number, and the colors are the same use 1 color

then repeat in a second conditional formatting equation changing the last "=" to "<>"
