When Textual processes pipeline files, it produces JSON output that provides access to the Markdown content and that identifies entities that were detected in the file.
Common elements in the JSON output
Information about the entire file
All JSON output files contain the following elements that contain information for the entire file:
{"fileType":"<file type>","content": {"text":"<Markdown file content>","hash":"<hashed file content>","entities": [ //Entry for each entity in the file {"start": <start location>,"end": <end location>,"label":"<value type>","text":"<value text>","score": <confidence score>,"language":"<language code>" } ] },"schemaVersion": <integer schema version>}
For specific file types, the JSON output includes additional objects and properties to reflect the file structure.
Hashed and Markdown content
The JSON output contains hashed and Markdown content for the entire file and for individual file components.
Entities
The JSON output contains entities arrays for the entire file and for individual file components.
Each entity in the entities array has the following properties:
Plain text files
For plain text files, the JSON output only contains the information for the entire file.
{"fileType":"<file type>","content": {"text":"<Markdown content>","hash":"<hashed content>","entities": [ //Entry for each entity in the file {"start": <start location>,"end": <end location>,"label":"<value type>","text":"<value text>","score": <confidence score>,"language":"<language code>" } ] },"schemaVersion": <integer schema version>}

PDF and image files
PDF and image files use the same structure. Textual extracts and scans the text from the files.
For PDF and image files, the JSON output structure adds the following content.
pages array
The pages array contains all of the content on the pages. This includes content in tables and key-value pairs, which are also listed separately in the output.
For each page in the file, the pages array contains a page array.
For each component on the page - such as paragraphs, headings, headers, and footers - the page array contains a component object.
Each component object contains the component entities, hashed content, and Markdown content.
tables array
The tables array contains content that is in tables.
For each table in the file, the tables array contains a table array.
For each row in a table, the table array contains a row array.
For each cell in a row, the row array contains a cell object.
Each cell object identifies the type of cell (header or content). It also contains the entities, hashed content, and Markdown content for the cell.
keyValuePairs array
The keyValuePairs array contains key-value pair content. For example, for a PDF of a form with fields, a key-value pair might represent a field label and field value.
For each key-value pair, the keyValuePairs array contains a key-value pair object.
The key-value pair object contains:
An automatically incremented identifier. For example, id for the first key-value pair is 1, for the second key-value pair is 2, and so on.
The start and end position of the key-value pair
The text of the key
The entities, hashed content, and Markdown content for the value
