Looking for a formula that shows value of records are "duplicate" or "not duplicate"

Hi All,

I am looking for a formula that shows value of records are “duplicate” or “not duplicate”.

In Google Sheet, I use formula (=IF(COUNTIF(A:B,B1)>1,“duplicate”,“not duplicate”) but in Airtable, I can’t use same that formula.

Please help me, thanks All.

Hi there. Based on your formula, it seems like every record with a number bigger than 1 is a duplicate while the rest is not. So maybe just like this?

IF(Number > 1, "DUPLICATE", "NOT DUPLICATE")

In Airtable, you’re not checking for entire columns, but for every record (similar to row in Excel). So with the formula above, you’re basically saying: If the Number field in this record (row) is above 1, it’s a duplicate, otherwise it’s not.

Let me know if this was what you were looking for :slightly_smiling_face:

Thank you for answering me but I don’t understand your idea. Please get your formula in airtable, it did not working.
