Sources

Source nodes bring external data into a workflow. They usually start an iteration branch without requiring an incoming data connection, then output a DataFrame, NodeFile, or DataObject for downstream processing.

Use source nodes to:

  • Query relational databases with Visual Query or Query.
  • Import tabular file data from CSV, Excel, JSON, and Parquet files.
  • Read files from the B2Win Suite server, Windows shares, SharePoint, IDM, FTP, or SFTP.
  • Accept a user-uploaded file through File Uploader.
  • Call an external REST endpoint through Invoke OpenAPI or Invoke OpenAPI with Input.

Most file-based source nodes output one or more NodeFile values. Import Table nodes consume a file and output a DataFrame. OpenAPI source nodes output a DataObject containing the JSON response.
