Form Recognizer extracts information from forms and images into structured data. It includes the following options:

  • Read - Extract text from documents.
  • Layout - Extract text and layout information from documents.
  • Document - Extract text, layout, entities, and general key-value pairs from documents.
  • Business Card - Extract key information from business cards.
  • ID Document - Extract key information from passports and ID cards.
  • Invoice - Extract key information from invoices.
  • Receipt - Extract key information from receipts.
  • Health Insurance Card - Extract key information from US health insurance cards.
  • US W2 Tax - Extract key information from IRS US W2 tax forms (year 2018-current).
  • US 1098 Tax - Extract key information from United States Internal Revenue Service Form 1098 (2021-current).
  • US 1098-E Tax - Extract key information from United States Internal Revenue Service Form 1098-E (2021-current).
  • US 1098-T Tax - Extract key information from United States Internal Revenue Service Form 1098-T (2021-current).
  • Contract - Extract key information from legal contracts.
  • Custom - Extracts information from forms (PDFs and images) into structured data based on a model created from a set of representative training forms. Form Recognizer learns the structure of your forms to intelligently extract text and data. It ingests text from forms, applies machine learning technology to identify keys, tables, and fields, and then outputs structured data that includes the relationships within the original file.
