How to Extract Data from an Invoice with JavaScript?

In this tutorial, you will learn how to use Invoice Parsing API in 5 minutes using JavaScript. Eden AI provides an easy and developer-friendly API that allows you to extract structured informations from invoices.

What is Invoice Parsing? 

Invoice parsing is a process that uses optical character recognition (OCR), computer vision, and natural language processing (NLP) techniques to extract and digitalize relevant data from invoices.

It involves identifying the structure of the document and extracting key information such as the invoice ID, total amount due, invoice date, and customer name. Invoice parsers can help improve data accuracy by automating the data extraction process and reducing the potential for errors that can occur during manual data entry.

This extracted data can then be used for a variety of purposes, such as generating reports or exporting data to other applications. Invoice parsing is often used in conjunction with other business management tools to streamline processes and improve efficiency.
