What is the easiest method to retrieve the invoice number from a native PDF file?

Retrieving the invoice number from a native PDF file can be effectively accomplished by opening the PDF with Acrobat and scraping the information. This method takes advantage of Acrobat's built-in capabilities to interpret and display the content of the PDF accurately. As the document is rendered in Acrobat, you can easily identify and extract specific information such as the invoice number, which can typically be found in a standard location within the document layout.

Using scraping techniques in Adobe Acrobat allows for a more controlled extraction process, especially since you can visually confirm the relevant information. Furthermore, native PDFs maintain their formatting better than scanned documents, reducing the likelihood of errors during the extraction process.

In contrast, other methods may have limitations based on the document type or the quality of the data extraction. For instance, using OCR (Optical Character Recognition) is less effective for native PDFs as they are already text-based and do not require recognition of printed text. The Get Text activity might not target the specific content as effectively if the structure of the document is complex, and relying solely on UiPath's Extract Data might necessitate more complex configurations which could be avoided by directly using Acrobat.
