[Solved] How to delete an item from a delimited list?

Hi, :wave:

I am making an App, where I have stored a delimited list in an Airtable cell.

The Airtable area looks like image.

The "1,2,3,4" will be set to a list-viewer, with this block

What I exactly want is, when I select any item from the list, it should be removed from the Airtable cell.

For example, if I click "3" from the list, it should be removed from the list-viewer, and from the Airtable cell. Then the cell would look like - "1,2,4".

I tried doing it, and it didn’t work out well.

My blocks and the result

Neither Airtable reflect any changes, nor the list-viewer.

What should I do?
Thanks! :blush:

Hi, @jared! :wave:
Thanks for your reply! :blush:

Your idea works! :+1:

But, I have a small problem, which I forgot to say earlier (sorry for that) -

Now I have data in Airtable like :arrow_right: 1 - 2 - 3 | 4 - 5 - 6 | 7 - 8 - 9
Now with " | " as the master delimiter. So the items in the list would look like -

1 - 2 - 3
4 - 5 - 6
7 - 8 - 9

Your provided code, ultimately joins every list with “,”. How will I choose and delete “1 - 2 - 3” from a " | " delimited list?

Thanks again! :blush:

Hi, @jared :wave:

I have dropped my above idea, and now I would like to just replace an delimited item. For example, my list is delimited with " || " character, and list is like 1 || 2 || none || 4
And I would like to replace the item no. 3 in the list, which is “none” with another term.


  • I would get the list & un-delimit it,
  • Then I’ll get the 3rd term of the list, and replace it with something.
  • Then delimit it again with the " || " character.
  • And finally add it back to Airtable. So the new list would be 1 || 2 || 3 || 4

Any help is appreciated :smiley_cat:
Thanks! :blush:

How does this work for you?


The only thing missing is the airtable blocks. I imagine you are able to extract info from the cell you want and then to replace it.
