Proposed Changes:

Introduce new components for AWS Textract integration.

Textract API	Proposed Haystack Component	Supported Sources	Description
DetectDocumentText	AmazonTextractDocumentConverter	local, s3, PIL	Basic OCR. Extracts lines and words without forms or tables.
AnalyzeDocument	AmazonTextractStructuredDocumentConverter	local, s3, PIL	Extracts structured data like forms, tables, and optional queries.
AnalyzeID	AmazonTextractIDConverter	local, s3, PIL	Extracts identity fields from official IDs (e.g., driver’s license, passport).
AnalyzeExpense	AmazonTextractExpenseConverter	local, s3, PIL	Extracts fields, totals, and line items from receipts and invoices.

Example Usage

from haystack_integrations.components.generators.amazon_textract import AmazonTextractDocumentConverter

converter = AmazonTextractDocumentConverter()

results = converter.run(sources=["sample.pdf"], meta={"date_added": datetime.now().isoformat()})
documents = results["documents"]
print(documents[0].content)

Implementation Details

• AnalyzeID does not have an asynchronous API thus wont support multi page sources.
• Multipage PDFs must be stored on s3.

How did you test it?

Will add thorough unit and integration test in final PR.

Notes for the reviewer

This is an early draft intended to gather feedback and input from the core team. To keep the scope of this PR focused and manageable, I'm starting with the AmazonTextractDocumentConverter. I will gather feedback then finish implementation, testing, and docs. Pending future approval, I plan to follow up with additional PRs implementing the other proposed components.
