Object Array Converter

Description

This module converts data between object and array formats bidirectionally. It automatically detects whether the input is an object or an array and applies the corresponding conversion. For objects, it can extract values (values), key-value entries (entries), or both. For arrays, it can convert to object using numeric indices (index) or a specific property as key (key). It is useful when a downstream module requires a different data format than what the upstream module produces.

Configuration

Parameters

Parameter	Type	Required	Description
mode	string	No	Conversion mode for objects: values (values only) or entries (key-value pairs). Default entries.
toObjectBy	string	No	Conversion mode for arrays: index (uses numeric index as key) or key (uses an object property as key).
keyField	string	No	When toObjectBy is key, name of the object property to use as key.
continueOnError	boolean	No	If true, continues the flow even if there are errors. Default true.

Output

{
  "nextModule": "siguiente_modulo",
  "data": {
    "0": { "id": 1, "name": "Item A" },
    "1": { "id": 2, "name": "Item B" }
  }
}

Usage Example

Basic case

Convert object to array of values:

{
  "mode": "values"
}

Convert array to object by property:

{
  "toObjectBy": "key",
  "keyField": "id"
}

Notes

• Input type detection is automatic (object vs array)
• If the input is neither object nor array (e.g.: string, number), it returns an error
• For array to object conversion with toObjectBy: "key", if an element doesn’t have the indicated property, it is skipped
• The entries mode returns an array of [key, value] pairs
• The values mode returns an array with only the object values
