Hello, I am trying to remove the brackets `[]` at the output of my payload

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/3/e3f98d7281a73b51de243e690bdd6ef5f7aa6bfa.png)

If I get "27" or "25" it gives me a text result, but the problem is that the sensor reading gives me ["27.500"]

How can I remove those `[]`?

Thank you

You are receiving a json string representation of an array. You can select in the mqtt node to automatically parse this to a javascript object.

Once you have done this you can copy the path to the element in the array from the debug sidebar and use this path in a change node to set your payload to that element.
