Store a key with a value in a local JSON file. Multiple keys could be saved in a single file.

Create a subfolder in your n8n home directory: `/home/node/.n8n/local-files`. In Docker, look at the data path and create a subfolder `local-files`.
Set the correct access rights with `chmod 1000:1000 local-files`.
Put the workflow code in a new workflow named `WriteKey`.
Create another workflow with a `function item`:
```js
return { file: "/4711.json", // 4711 should be your workflow id key: "MyKey", value: "MyValue" }
```
Pipe the `function item` to an `Execution Workflow` that calls the `WriteKey` workflow.
It would be nice if we could get someday a shiny built-in n8n node that does the job. :)

How to import this workflow into n8n
1Purchase or download the workflow to get the n8n workflow JSON file.
2In your n8n instance, open Workflows and choose "Import from File" (or paste the JSON with Ctrl+V on the canvas).
3Open each node marked with a credential warning and connect your own accounts and API keys.
4Run the workflow once manually to verify the data flow, then toggle it to Active.
