Analyze Document with AWS Textract (Synchronous, Structured Extraction)

textract_analyze_document.Rd

This function calls the AWS Textract AnalyzeDocument API (synchronous) to extract structured data including forms (key-value pairs), tables, and layout from documents. Note: This is a synchronous operation with a 5 MB file size limit. For larger files, the function automatically converts the first 2 pages to PNG format.

Usage

textract_analyze_document(
  file_path,
  features = c("TABLES", "FORMS"),
  aws_access_key_id,
  aws_secret_access_key,
  aws_region = "us-east-1"
)

Arguments

file_path

Character string. Path to a local PDF, PNG, JPEG, or TIFF file.

features

Character vector. Features to extract: "TABLES", "FORMS", "LAYOUT", "SIGNATURES".

aws_access_key_id

Character string. AWS access key ID.

aws_secret_access_key

Character string. AWS secret access key.

aws_region

Character string. AWS region. Default is "us-east-1".

Value

List containing the raw Textract API response with Blocks.

Warning

This function uses the synchronous Textract API which has a 5 MB file size limit. For PDFs larger than 5 MB, only the first 2 pages will be automatically extracted and converted to PNG format. For full document processing of large files, consider using the asynchronous S3-based Textract workflow or an alternative service like Google Document AI (20 MB limit) or Azure Document Intelligence (500 MB limit).
