Can you copy the data using the "Copy Value" button

and paste the msg data into a reply (inside a code block).  
It is hard to recreate data from a screenshot.

  

Also, please dont post pictures of code (they are not searchable and most people wont re-type your code to help you solve it)

`{"":"14h00-22h00"}`

```var

input = msg.payload;
 var vroeg = input.includes("06h00-14h00",0);
var late = input.includes("14h00-22h00",0);
if(vroeg === true) {
    Pippo = 1;
}

if (late === true){
    Pippo = 2;
} 
    

msg.payload = Pippo;

return msg;

Anyhow, you can use the [`Array.find`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find) function to search an array of objects.

e.g:

```auto
let pippo
const input = msg.payload
const vroeg = !!input.find(e => e[''] === '06h00-14h00')
const late = !!input.find(e => e[''] === '14h00-22h00')

if (vroeg === true) {
    pippo = 1
}

if (late === true) {
    pippo = 2
}

msg.payload = pippo

return msg

```

The data object is not really very valid as an object. That's why your includes doesn't work. You are looking in the array for a string but the array contents are objects with a very odd key `""`.

I would suggest fixing the Excel data output.
