I have a table of information.


you can seen cell C15 shows certification number is 2.


What formula should I use in cell C16 so it shows 123, 321, 111.


concatenate unique values only, based on criteria without macros?


How is it done?


Thank you in advance.

Without macros, you'd need the TEXTJOIN function available in Excel 365.

I will give it a try on 365.

What can be done on 2016?

Would using text join be an option on 2016?

No, TEXTJOIN is not available on 2016. It might be on 2019, and definitely is on 365. If you don't have one of those options, you'll have to use a helper column, like Dante's example. It's also worth noting that if you do use a helper (auxiliary) column, you can hide it so you don't have to see it.

you can try with PowerQuery (Get&Transform)
