JSON Output

JSON output file types produced by ABBYY Vantage skills: file names, export options, schemas, and which Document, OCR, or Process skill creates each.

The following table describes the available JSON output file types. The Skill type column lists the skill types that can generate each file type. For the full list of Vantage output formats, see Output file types.

File type	Export option	Description	Skill type	File name	JSON schema
Fields (JSON)	Values, metadata, and field structure for each document	A file containing classification results (if Classification skill was applied), full data extraction results (if Document skill was applied), rule errors, document and transaction registration parameters (if available), and other metadata.	Document Classification Process	<Applied_skill_name>.json *	JSON schema
Fields (JSON)	Values only	A file containing field values and rule errors.	Document Process	<Applied_skill_name>_fields.json *	Depends on the Document skill used. Currently not available for download.
Text (JSON)	Text only	This mode is suitable for extracting all text from the input image, including small text areas of low quality. The document appearance and structure are ignored, pictures and tables are not detected. It is designed for the situations when you need to retrieve the data from the image for some further processing on your side, such as extracting data from bills, receipts or invoices. Selecting this mode makes export to DOCX and XLSX impossible.	OCR Process	OCR: <First_source_file_name>.json ** Process: <Applied_skill_name>_text.json *	OCR skill schema
Text (JSON)	Preserve document structure	This mode is focused on retaining the original document structure and appearance, including font styles, pictures, background color, etc., and is more focused on documents like agreements, contracts, specifications.	OCR Process	OCR: <First_source_file_name>.json ** Process: <Applied_skill_name>_text.json *	OCR skill schema

* <Applied_skill_name> will be one of the following:

• The name of the skill if a transaction was created for a Document or Classification skill.
• If a transaction was created for a Process skill:
  • the name of the last Document skill applied to the document
  • the name of the last Classification skill applied to the document if no Document skills were applied
  • “Unknown” if no Document and Classification skills were applied, while at least one of them exists in the Process skill flow.

** <First_source_file_name> will be the name of the first file used to assemble the document, such as “IMG_12234”.

The Document skill always generates both Fields (JSON) files. Process skill settings allow you to select one Fields (JSON) file and/or one Text (JSON) file. OCR skill settings allow you to select one Text (JSON) file.

If a transaction fails, you can get information about the error in JSON format via the Vantage API. The JSON string contains information about the transaction, the error message, as well as names and identifiers of all source files in the transaction. This string will also be exported to the Error.json file in the output shared folder if you configure the Output activity of a Process skill accordingly.
