File Reader Overview

Transform documents and data files into structured information for your automation workflows

File Readers understand how your files are formatted and extract data to use in automations. They process different document types and transform unstructured content into structured information that can be used throughout your workflow.

Maximum File Size: File Readers can process files up to 250MB in size. This limit applies to all file types and reader types. Processing time may vary based on file size and complexity.

File Reader Types

Elementum provides specialized File Readers for different document formats and use cases:

Text File Reader

Extract raw text from images, text documents, and PDFs using OCR technology

Purchase Orders Reader

Process purchase orders with OCR trained specifically on PO fields and formats

Table File Reader

Read Excel and CSV files with support for thousands of rows and multiple sheets

Elementum Intelligence Reader

AI-powered document analysis for complex text, image, and PDF documents

JSON File Reader

Parse JSON data with AI-assisted field detection and automatic type mapping

How File Readers Work

Integration with Automations

File Readers are used within automation workflows to process documents when specific events occur:

Document Uploaded → File Reader Processes → Structured Data → Automation Actions

Example Workflow:

1. Email Received trigger fires with PDF attachment
2. File Reader action processes the PDF
3. Create Record action uses extracted data
4. Send Email Notification confirms processing

Processing Pipeline

1. File Input

   Documents are uploaded or received through triggers like Email Received or Attachment Added

2. Content Extraction

   File Reader analyzes the document using OCR, AI, or structured parsing

3. Data Mapping

   Extracted information is mapped to defined fields with appropriate data types

4. Automation Integration

   Structured data flows into subsequent automation actions
