The document shown is an invoice with a consistent layout, known fields (e.g., invoice number, date, line items, shipping & handling, totals). In Document Understanding, such a document is classified as a fixed structured format.
As per UiPath's definition:
"Fixed structured format documents are documents with a well-defined and unchanging structure, such as invoices, purchase orders, and utility bills." These documents are typically the easiest to work with because the location and format of fields do not vary, enabling highly accurate extraction using form-based extractors or pre-trained models.
