Azure AI Document Intelligence
Extracts text, tables, key-value pairs, and document-specific fields
Why learn Azure AI Document Intelligence?
Teams use Azure AI Document Intelligence to adopt intelligent document processing without building the complete underlying platform themselves.
The problem it solves
Extracts structured text and fields from forms and documents
Where it came from
Azure AI Document Intelligence is Microsoft Azure's offering for intelligent document processing. Its closest catalog counterparts are Amazon Textract and Google Cloud Document AI; they address the same broad need but are not feature-for-feature identical.

Real World Example
Automated Logistics Invoice Processing
Logistics and freight forwarding companies managing thousands of paper-based shipping manifests and invoices.
The business problem
Manual data entry of complex shipping tables and key-value pairs from inconsistent vendor documents causes significant operational delays and high error rates.
How this topic solves it
Azure Document Intelligence in Foundry Tools automates the extraction of text, tables, and specific document fields, transforming unstructured physical documents into structured digital data for downstream ERP integration.
- Configure a Document Intelligence resource in the Azure portal.
- Select a prebuilt model or train a custom model to recognize specific shipping manifest layouts.
- Submit document images or PDFs to the service endpoint via API.
- Parse the returned JSON output to map extracted key-value pairs and table rows to database schemas.
- Validate extracted data against existing purchase order records.
The flow shows how raw documents are processed into structured data.
AI service for extraction
Extracted key-value pairs
Final database storage
- Vendor Document → Submit for analysis → Document Intelligence
- Document Intelligence → Returns extracted fields → Structured JSON
- Structured JSON → Map and store data → ERP System
Implementation example
This code illustrates the interaction with the service to trigger extraction of structured data from a document stream.
# Hypothetical snippet for document analysis
# client.begin_analyze_document(model_id, document_stream)
# The service extracts tables and key-value pairs automatically
# result = poller.result()
# for table in result.tables: # Accessing extracted table dataExpected business outcome
Increased processing speed and improved data accuracy by reducing human intervention in the document ingestion pipeline.
Limitations and checks
The service may struggle with extremely low-resolution scans or highly distorted document layouts, which requires implementing pre-processing checks to verify image quality before submission.
