Help needed parsing csv as json and get sum of them

[umtksa]

I'm trying to parse a csv file
I can parse it like this but I cannot get sum of all "Total"
it has 8 entries on this example but it can be 1 or 19 sometimes
can someone point me to the right direction

Hi Umtksa,

Try this in your function node :

let total = 0;

msg.payload.forEach( el => {

    total += Number(el.Total.replace("$",""))
})

msg.payload = total

return msg;

[EDIT] basically with this, we loop with forEach through all the elements (el) of your array
do some processing to replace the dollar sign and convert to a number ready to be added to the total variable we defined at the start.

thank you for your help,
with your code I can can get sum of total and quantity with seperate function
then I try to do it inside one function and push them to a template node to show on dashboard but I'm failing somehow

The problem was that you were returning your msg before finishing the rest of the calculations.
Do the return at the end
