![]() I’ve highlighted the text elements that we need to save in the Google Sheet and the RegEx pattern that will help us extract the required information. Use the python ocrmypdf library, which uses googles powerful Tesseract OCR to automatically OCR a scanned PDF file and extract certain elements for accounti. There are 3 types of uploads you can perform: Simple upload ( uploadTypemedia) Use this upload type to transfer a small media file (5 MB or less) without supplying metadata. For information about how to create a metadata-only File, refer to Create files. To be eligible for OCR, the ItemMetadata.mimeType for the item must be specified as application/pdf and a PDF file must contain only scanned images. The Google Drive API lets you upload file data when you create or update a File. ![]() Now that we have the text content of the PDF file, we can use RegEx to extract the information we need. Note: Cloud Search uses OCR for PDF files only when indexing in ASYNCHRONOUS mode, and applies OCR to the first 80 pages of the PDF file. Please ensure the Advanced Drive API as describes in this tutorial. The Vision API can detect and transcribe text from PDF and TIFF files stored in Google Cloud Storage. Convert PDF to TextĪssuming that the PDF files is already in our Google Drive, we’ll write a little function that will convert the PDF file to text. In this lesson, you will learn how to combine the two to make the most of their individual strengths and achieve even more accurate OCR results. ![]() We can then use RegEx to parse this text file and write the extracted information into a Google Sheet. OCR with Google Vision API and Tesseract Isabelle Gribomont Google Vision and Tesseract are both popular and powerful OCR tools, but they each have their weaknesses. Our PDF extractor script will read the file from Google Drive and use Google Drive API to convert to a text file. The Google Cloud Vision API enables developers to create vision based machine learning applications based on object detection, OCR, etc. Here’s a sample PDF invoice that we’ll use in this example. Google Vision API also lets you implement OCR in your RPA workflows. It goes beyond simple optical character recognition (OCR) to also identify the contents of fields in forms and information stored in tables. These PDF invoices have to be parsed and specific information, like the invoice number, the invoice date and the buyer’s email address, needs to be extracted and saved into a Google Spreadsheet. Google Vision is a cloud OCR service that automatically detects and extracts text and data from scanned documents and PDF files. This tutorial explains how you can parse and extract text elements from invoices, expense receipts and other PDF documents with the help of Apps Script.Īn external accounting system generates paper receipts for its customers which are then scanned as PDF files and uploaded to a folder in Google Drive.
