![]() Also, additional user-defined rules are added on top of the predictions made by AI. In this step, the extracted data is converted into the required format such as CSV, XML, JSON etc. Also, since it employs ML at its core, it can be retrained with custom data to fit your company’s use case. Most ML models used for data extraction from PDFs contain a combination of optical character recognition tools, text and pattern recognition tools etc.įor the purpose of this post, we can treat the model as a black box which takes your PDF document as an input and spits out the parsed information. Data extraction is usually carried out by a Machine Learning(ML) model. The following Nanonets post Nanonets Tesseract Post contains some great examples of how documents can be preprocessed before Optical Character Recognition(OCR) is run on them. Noise removal by using appropriate filters, binarization, skew correction etc are some of the most common preprocessing steps. For example, if the PDF document has been scanned, it is bound to contain some scan artifacts which could affect the performance of the converter. The better your PDF looks, the easier it will be for your Machine Learning model to extract or capture data from it. Let’s briefly take a look at each step of the process: 1. Flowchart illustrating typical flow of modern PDF Parsers Most modern PDF parsers make use of the flow described below to parse unstructured data from PDF documents. The Modern Approach to Parsing PDF Documents The next section talks about the approach taken by most modern PDF parsers to recognize/parse information from a PDF document. Hopefully, you are convinced that converting a PDF document into a Google Sheets form is no walk in the park. If you think that text extraction is difficult, extracting the data present in tables is even more challenging owing to widely varying tabular formats which are used. This is because the PDF format simply consists of instructions on how to print/draw a sequence of characters on a page. ![]() The above pictures make it clear that when information is stored in a PDF, its original structure is completely lost. Screenshot of the PDF opened using a text editor Let’s try opening the same PDF document using a text editor. The above image shows the screenshot of a PDF document which is opened using a PDF reader. So, why is it so challenging to parse a PDF and convert its contents to another format? The following images speak a thousand words and will drive the point home. It has since been widely adopted as it is agnostic to the underlying operating system. The portable document format was a file format initially developed by Adobe and was later released as an open standard.

Now that the need for converting PDFs to a Google sheet form is clear, let’s take a look at how PDF documents are structured and what the challenges are in parsing them. The Finance section pays your supplier and makes an entry in the company's ledger.Īpart from being a long drawn out process, this is error prone and it would make much more sense to simply automate it. Someone manually goes through the invoice and keys in the required information into a Google Sheets document before forwarding it to the Finance section. Your Accounts Payable team receives an invoice, in the standard PDF format. At the same time, a large number of companies have also started using Google Sheets integrations to automate tasks. Why Convert PDFs to Google Sheets?Īccording to this Google blog post from the official Google blog page, more than 5 million businesses are using their G Suite solution. You will also learn how Nanonets can automate the entire workflow of converting PDF to Google Sheets online.īefore we look at how to convert PDF to Google Sheets, let’s take a look at why it's important to do this.
