Attachment Utils Connector

Attachment Utilities provides tools for transforming, extracting, and converting data from file attachments and URLs.

Attachment Utilities is a versatile toolkit for file extraction, conversion, and enrichment within the Swimlane Turbine platform. It enables users to automate the processing of attachments—such as converting files to and from Base64, extracting text or images, transforming spreadsheets to JSON, and downloading files from URLs—without writing code. By integrating Attachment Utilities, Swimlane Turbine users can streamline data ingestion, accelerate content analysis, and enhance the efficiency of security workflows through seamless file handling and enrichment capabilities.

Action Limitation

Extract Images from HTML

This action can extract images from a HTML file only if full paths are available to image sources (i.e., something like http://<base_url>/<path_to_image>).
