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)

Thank you Steve .... i did thisfor now, i'm really new on node-red but looking in the forum i had lot of help

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

var Pippo ;
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;

where is this data being generated? It is most odd!

Anyhow, you can use the Array.find function to search an array of objects.

e.g:

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 are generated in a sheet of excel i reading a woorkbook if i found this data i will send to a Siemens plc to start warmup of a gloe machine

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.
