What is a PDF Parser? An introduction to PDF and Document Parsing

A PDF Parser (also sometimes called PDF scraper) is a software which can be used to extract data from PDF documents. PDF Parsers can come in form of libraries for developers or as standalone software products for end-users.

PDF Parsers are used mainly to extract data from a batch of PDF files. Manual data entry (copy & paste) is a common alternative when data needs to be extracted from only a handful of documents.

What kind of data can be parsed from PDF files?

PDF files are the go-to option for many different document types, ranging from books, presentations, reports, brochures to invoice and purchase orders. While PDF offers the capability to embed rich media types and attachments, PDF parsing solutions are typically used to extract:

  • Text paragraphs
  • Single data fields (dates, tracking numbers, …)
  • Tabular data (tables and lists)
  • Images

What are typical use-cases for a PDF Parsers / PDF Scraper?

PDF parsers are used in various fields, ranging from document management, document indexing to business process automation with the goal of automatically extracting data from PDF files. Whether or not it is possible to successfully parse PDF files, depends highly on the nature of documents and not all document types can be parsed. Use-cases we see quite often at Docparser, are Automated Invoice & Accounts Payable Processing, Purchase Order Parsing, PDF Form Processing, Converting PDF bank statements, etc.

Is parsing a PDF comparable to web scraping? And what is a PDF scraper?

Parsing PDF files is indeed very similar to scraping data from websites. Some people actually use the word “PDF Scraper” instead of PDF Parser. Scraping data from websites comes however with the advantage that websites typically come as hierarchically structured HTML documents. Being able to access HTML tags (e.g. <h1>, <h2>, <table>, …) makes it much easier for a software to “understand” the structure of a document. Unfortunately, the PDF specification does not contain any structuring tags. For example, a table inside a PDF file is basically just text which is arranged in a certain way. Having no structural tags makes it challenging to successfully parse PDF files.

  1. Hi Doc Parser Team

    Just wondering can the software import scraped data directly into a HTML email template? For example I want to be able to create parsing rules that recognise dates and invoice amounts directly from the PDF file and import it into the corresponding data fields in an email template?

    Thanks

    1. Hi Aneta, Docparser does not have any outbound email functionalities at the moment. You can however send the parsed data to one of our integration platform partners (Zapier, MS Flow, etc.). Once your data is parsed and was sent through the integration, you can use it to fill and send HTML layout based emails.
