Form Recognizer API (v2.0)

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

  • Form - 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.
  • Receipt - Detects and extracts data from receipts using optical character recognition (OCR) and our receipt model, enabling you to easily extract structured data from receipts such as merchant name, merchant phone number, transaction date, transaction total, and more.
  • Layout - Extracts text and table structure from documents using optical character recognition (OCR).

Request body

Response 200

JSON fields in the response body:

Field Type Description
status String Analyze Layout operation status. Possible values:
  • notStarted: The analysis operation has not started.
  • running: The analysis operation is in progress.
  • failed: The analysis operation has failed.
  • succeeded: The analysis operation has succeeded.
If the status is succeeded, the response JSON will include the layout and text recognition results. The layout result is organized as a list of tables for each page. When includeTextDetails is true, the detailed text recognition result is organized as a hierarchy of lines and words, with text, bounding box and confidence information.
createdDateTime String Date and time (UTC) when the operation was created.
lastUpdatedDateTime String Date and time (UTC) when the status is last updated.
analyzeResult Object Results of the analyze operation.
version String The version of schema used for this result.
readResults [Object] List of of extracted text result for each page in the input document.
page Integer The 1-based page number in the input document.
width Number The width of the image/PDF in pixels/inches, respectively.
height Number The height of the image/PDF in pixels/inches, respectively.
unit String The unit used by the width, height and boundingBox properties. For images, the unit is "pixel". For PDF, the unit is "inch".
angle Number The general orientation of the text in clockwise direction, measured in degrees between (-180, 180].
language String The detected language on the page overall or of a specific line if different from the page.
lines [Object] List of text lines. The maximum number of lines returned is 300 per page. The lines are sorted top to bottom, left to right, although in certain cases proximity is treated with higher priority. As the sorting order depends on the detected text, it may change across images and OCR version updates. Thus, business logic should be built upon the actual line location instead of order. This field only appears when includeTextDetails is set to true.
words [Object] List of words in the text line.
boundingBox [Number] Quadrangle bounding box of a line or word, depending on the parent object, specified as a list of 8 numbers. The coordinates are specified relative to the top-left of the original image. The eight numbers represent the four points, clockwise from the top-left corner relative to the text orientation. For image, the (x, y) coordinates are measured in pixels. For PDF, the (x, y) coordinates are measured in inches.
text String Extracted field text in documentResults, or the text content of a word/line in readResults.
confidence Number Confidence value.
pageResults [Object] Page-level information extracted from the input.
page Integer Page number.
tables [Object] List of data tables extracted from the page.
rows Integer Number of rows.
columns Integer Number of columns.
cells [Object] List of cells contained in the table.
rowIndex Integer Row index of the cell.
columnIndex Integer Column index of the cell.
rowSpan Integer Number of rows spanned by this cell.
columnSpan Integer Number of columns spanned by this cell.
elements [String] When includeTextDetails is set to true, a list of JSON references to the text elements constituting this field.
