Is there a way to iterate over a combination of parameters using a "for each" task?

[sys08001]

Hi,

I have a notebook with two input widgets set up ("current_month" and "current_year") that the notebook grabs values from and uses for processing. I want to be able to provide a list of input values in the "for each" task where each value is actually a value pair corresponding to the widget values e.g. ("January", "2023") and then specify that I want the notebook task to be iterated over using the paired values. I have only been able to find instructions for iterating over values corresponding to a single parameter (e.g. you can provide an input list ["January", "February", etc.] in the for each task and then create a parameter in the notebook task of "current_month" set equal to "{{input}}") and was wondering if what I'm trying to accomplish is possible?

Hi there @sys08001 , yup it is possible 

you can pass the input values for the for_each task in json format 
Somewhat like this

[
  {
    "tableName": "product_2",
    "id": "1",
    "names": "John Doe",
    "created_at": "2025-02-22T10:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "2",
    "names": "Jane Smith",
    "created_at": "2025-02-22T11:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "3",
    "names": "Alice Johnson",
    "created_at": "2025-02-22T12:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "1",
    "names": "John Doe",
    "created_at": "2025-02-22T10:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "2",
    "names": "Jane Smith",
    "created_at": "2025-02-22T11:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "3",
    "names": "Alice Johnson",
    "created_at": "2025-02-22T12:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "1",
    "names": "John Doe",
    "created_at": "2025-02-22T10:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "2",
    "names": "Jane Smith",
    "created_at": "2025-02-22T11:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "3",
    "names": "Alice Johnson",
    "created_at": "2025-02-22T12:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "1",
    "names": "John Doe",
    "created_at": "2025-02-22T10:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "2",
    "names": "Jane Smith",
    "created_at": "2025-02-22T11:00:00.000Z"
  },
  {
    "tableName": "product_2",
    "id": "3",
    "names": "Alice Johnson",
    "created_at": "2025-02-22T12:00:00.000Z"
  }
]

and then can in the each task you can use {{input.field_name}}

for you usecase , you can create a json input like this 
[ { "month": "January", "year" : "2025" }, ... ]
and then in the each task you can use input.month or input.year to call it, 
you can create two separate parameters for calling them or can have them in a single parameter as well  
by referencing them like this

( {{input.month}} , {{input.year}} )
