Overview

The Object Block creates an object from input values and a JSON template. It automatically escapes input values and inserts them into the template, supporting any data type as input and outputting an object.

​
Inputs

​
(Dynamic)
any

Input values to be inserted into the JSON template. Input names are dynamically generated from the JSON template based on values wrapped in double curly braces (e.g. {{input}}). Non-string inputs are automatically converted to strings.

​
Outputs

​
output
object | object[]

The object or array created from the input values and JSON template. The type will be object[] if the template defines an array, otherwise it will be object.

​
Editor Settings

​
jsonTemplate
code
default:"{ \"key\": \"{{input}}\" }"

The JSON template for creating the object. Input values are inserted into this template using double curly brace syntax (e.g. {{input}}). The template must be valid JSON.

Values wrapped in quotes (e.g. "{{input}}") will be treated as strings and escaped appropriately. Values without quotes will be inserted directly as JSON values.

​
width
number
default:200

The width of the block in pixels.

​
hidden
boolean
default:true

Whether the block is hidden in the block menu.

​
Example: Creating an object from multiple inputs

  1. Add an Object Block and set the JSON Template to: 
    {
  "name": "{{name}}",
  "age": {{age}},
  "job": "{{job}}"
}
  2. Add two Text Blocks with values “John Doe” and “Engineer”. Connect to name and job inputs.
  3. Add a Number Block with value 30. Connect to age input.
  4. Run the flow. The Object Block output will be: 
    {
  "name": "John Doe",
  "age": 30,
  "job": "Engineer"
}

​
Error Handling

The Object Block will error if:

  • The JSON Template is not a valid JSON string
  • The interpolated JSON string (after inserting input values) is not valid JSON
