Need help with formula

I want to be able to filter records and have the record numbers all concatenated into a single, comma-delimited, field. Possible?. I have tried ARRAYJOIN and CONCATENATE. Want to be able to copy all the filtered record numbers as a comma delimited text to be able to paste onto another program.

Hi @Patricio_Suarez - you can only concatenate fields within a record, not the same field across records. However, there is a way to do this.

Create a new table with a single record:


Here I’ve used a dot/period as the ID, but it could be anything.

In your original table, link all records to the new table dot record:

Back in the link table, you can see all of the records IDs in a single field:

You can transform these into a comma-separated list using the formula:

ARRAYJOIN({Table 3})


Thank you so much for your help. Just tried your method and it works but I cannot only get filtered results to be passed onto the second table.

Want to be able to filter records:

and have only the record numbers from the filtered records go to the other table

I am limiting the records to be selected to a single view and I am filtering the content of that view.

Am I doing something wrong?

Incredibly grateful for your help.

You’re not doing anything wrong. Unfortunately rollup fields don’t recognize filters. They operate on all records in a table, filtered or not. That said, you can still get what you want.

Add a formula field named {Sold Records} to your main table, using the following formula (changing the names to match your fields as needed):

IF(Sold, {Record No.})


In the link table, add a rollup field:

The ARRAYCOMPACT(values) aggregation function will strip out the blank records, leaving only those with record numbers present.

Thank you so much. This worked. Very obscure way to do something that, seems to me, should be something easy to do.

I guess I have to use IF(SEARCH PARAMETER, {Record No.}) to get record numbers out of Airtable. I am also experimenting with copying the numbers directly from the Records No. column and reformatting them somehow to display as comma delimited text. They export with a return carriage between numbers.
