How can I combine all objects in an array into one object?

Hey!
Concatenate all objects in the array into one object.

To get it like this:

Hey @Roket,

You can reuse the code from here:

Thanks, @harshil1712!

I’ve looked at this page before.
This documentation does not contain an example with a solution to my problem.
I need to create one new object instead of an array of objects.

Hey @Roket,
Ah, yes. I shared that with you as a reference. You will of-course have to modify the code for your use case :slight_smile:

@Roket Your function node node should look like:

const results = []

for (const item of items) {
    let data = item.json.data;
    
    data = data.reduce((obj, value) => Object.assign(obj, { [`${Object.keys(value)[0]}`]: Object.values(value)[0]}), {});
  
    results.push({
      json: {
        ...item.json,
        data
      }
    })
}

return results
