Not sure if this is the right place to post this question but here goes.
How in Excel can I compare columns on a worksheet with columns on another worksheet and display a result.
Basically I have a list of values on worksheet 1 (master) that have either expired (Have an expiry date usually in the past) or are still live (have no expiry date) and I want to compare a separate list of values on a separate worksheet (slave) to identify what updates need to be applied to the slave to bring it up to date with the master.
I need to know whether there are new entries on the master that are not on the slave and need to identify any entries that are on both that on the master have now expired and also identify whether I have any entries on the slave that do not appear on the master i.e. they now need to be removed from the slave.
The purpose being to be able to identify what changes need to be made to the slave to bring it back in line with the master.
Hope the above makes sense.
