Dynamic Create Data

The Dynamic Create Data component creates a Data object or Message with configurable fields. Define the table in the Input Configuration field, and the component creates corresponding input or output handles in the component.

Use the Dynamic Create Data component in a flow

The following example demonstrates how to use a Dynamic Create Data component to create a structured Data or Message object from multiple sources.

1. Add the Dynamic Create Data component to your flow.

2. To define your data's fields, in the Input Configuration field, click Open table.

3. To add rows to your table, click Add a new row. Adding a new row creates input and output handles for the Field Type. For example, if you add a Text type field, thenText input and output handles are added to the component. For each new row, configure the Field Name and Field Type.

   • Field Name: The name of the field used as both the internal key and display label.
   • Field Type: The type of input field to create. The type options are:
     • Text: Accepts direct text input or accepts Text or Message output from other components.
     • Data: Accepts Data input from other components.
     • Number: Accepts direct numeric input or accepts Text or Message outputs from other components.
     • Handle: Accepts Text, Data, or Message output from other components.
     • Boolean: Accepts Boolean values. Cannot accept input from another component.

   For more information, see Langflow data types.

4. Depending on your Field Type selections, either connect output from other components to dynamically populate the inputs, or enter values manually in the Dynamic Create Data component's fields.

5. Select the desired output type at the component's output port. The component outputs either a Data object containing all field values from the component's inputs, or a Message containing all field values formatted as a text string.

Dynamic Create Data parameters

Some parameters are hidden by default in the visual editor. You can modify all parameters through the Controls in the component's header menu.

Name	Display Name	Info
form_fields	Input Configuration	Input parameter. A table that defines the dynamic form fields.
include_metadata	Include Metadata	Input parameter. Whether to include form configuration metadata in the output.
form_data	Data	Output parameter. A Data object containing all field values from the dynamic inputs.
message	Message	Output parameter. A formatted Text message containing all field values in a human-readable format.
