Many to Many Relationship

Hi Michael and welcome to the forum,

I've seen Many to Many relationships in Access and worked with them there like:

But you are asking about them in Excel (I assume). The tool to deal with relationships in Excel is at:

I hope the above helps, but without having a workbook sample of your data and what you expect as an answer, it is hard to do much more.

You can attach a sample workbook on our site and we can try to help from there.

Attach a sample workbook. Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.

If that takes care of your original question, please select Thread Tools from the menu link above and mark this thread as SOLVED. Thanks.
