Structured Output Parser

how do I have it start with 1 instead of 0? how can I extract / link this output to the next node, like send to Gmail?

In n8n, arrays are always 0-indexed by default. If you want your numbering to start from 1, you can use a Function node to transform the array before sending it to the next node. Example:

return items.map((item, index) => {
item.json.number = index + 1; // starts from 1
return item;
});

Then you can link this output to Gmail (or any other node) and use {{$json.Executive Summary}} to reference the 1-based numbering in your email or message

where should I put the Function node?

@Jayraj_Chhaya

return items.map((item, index) => {
item.json.number = index + 1; // starts from 1
return item;
});

You need to put the node after the AI, if the AI is the one that outputs the data.

@Jayraj_Chhaya

return items.map((item, index) => {
item.json.number = index + 1; // starts from 1
return item;
});

does not seem to have any impact.

also, the Gmail node is having issue: NodeOperationError: this.getNodeParameter(…).trim is not a function (item 0) at ExecuteContext.execute

Hey, here is the flow, you can modify the body of the email as per your needs, based on my template. Add the code node after the AI:
