Read a value by key from a local json file.

Related workflow: WriteKey

Create a subfolder in your n8n homedir: /home/node/.n8n/local-files. In docker look at the data path and create a subfolder local-files.
Set the correct access rights chmod 1000.1000 local-files.

Put the workflow code in a new workflow named GetKey.

Create another workflow with a function item:

return  {
  file: '/4711.json', // 4711 should be your workflow id
  key: 'MyKey',
  default: 'Optional returned value if key is empty / not exists'

Pipe the function item to an Execution Workflow that calls the GetKey workflow.

It would be nice if we could get someday a shiny built-in n8n node that does the job. :)

Implement complex processes faster with n8n
