Hello everybody,
I am completely new to the topic of node red and hope that I get nice help here.
I'm trying to read a Json file with a button and only output the specific part in a debug for later sending a mail.
[{"id":"ef540693.b4aca8","type":"debug","z":"ba097cdb.476aa8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":830,"y":280,"wires":[]}]
sorry for my bad english

Hi, welcome to the forum.
You have only posted a debug node - so cant help you much with that.
Have you got the file reading part working?
You dont state what part?
Can I recommend you watch this playlist: Node-RED Essentials. It is by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in less than an hour. A small investment for a lot of gain.
Sorry 
As I said, I'm quite new to the topic of node red.
I would like to make a dashboard with 70 buttons, each button should be read from the json, button 1 = ID1 etc.
I watch Youtube;)

So if I understand, you want to dynamically generate a dashboard page full of buttons, based on the contents of some JSON data?
Yes
I googled a lot but found nothing suitable
Not suprising - but then a search around angular ng-repeat or similar would get you close.
Here is one way...

Your flow assembles a URL with https://ooscom.de/kanban/kanban.json/{{post}} where post is 2 - that makes https://ooscom.de/kanban/kanban.json/2
it wont work because there is nothing at https://ooscom.de/kanban/kanban.json/2 - try it in your browser.
