I want to sort on “value” and only return a 1 item, ie the 5th item. I determine the Item I want buy the following {{ (($json.data.length)*.05+2).toFixed(0) }}

You’ll probably want to use a function or code node and run against all items, returning only an array with the single item you want.

This is based on the new n8n code node:

Thank you, that is a very simple solution. For interest this is how I did it in Integromat where I am moving this from.

{{get(sort(87.array; “desc”; “value”); 85.95thRecord)}}value

I’m glad I use n8n and not Integromat :stuck_out_tongue:

Actually for completeness we should include the pairedItem so subsequent nodes know where the data came from

const indexToReturn = ($input.all().length * 0.5).toFixed(0);
return [
  {
    json: $input.all()[indexToReturn].json,
    pairedItem: indexToReturn,
  }
];
