Create node red array with equal values

General
1

Hello!

Is it possible to put all values where the topic is the same in an array.

I have a list where there are several dates and they all have to be put together where the topic is the same to make them into an array.

It's like a switch but you don't have to enter the value.

I hope that someone can help me there.

Do you want something like this?

Msg.topic = "TopicValue"
Msg.payload = [date1, date2, date3, etc]

Not really visualizing what you want here

Or do you have an array of objects and want something like this

Msg.payload = [{"Date" : Date1}, {"Date": Date2}]

Hello!

Thanks for the reply.

It should then look like this.

If the topic or article number is different then he should make the entry in a new array.

Is there a better solution?
