PDF Parser API
GroupDocs.Parser Cloud SDK for .NET is an amazing API offers the capabilities to programmatically manipulate PDF files online. Not only it offers the PDF creation or conversion capabilities, but you can easily extract PDF file elements such as Text, Image, Attachments, Bookmarks etc. In this article, we are focused on text extract from PDF file using .NET Cloud SDK.
🔧 Prerequisites
Before we begin with PDF manipulation process, we need to ensure that the following components are installed:
- A GroupDocs Cloud account – sign up to get your Client ID and Secret.
- .NET 6.0 or higher installed.
- Visual Studio or any IDE that supports .NET development.
Installation
Install the SDK directly from NuGet Package Manager:
Install-Package GroupDocs.Parser-Cloud
Extract PDF Text using C#
Please follow the steps given below to programmatically get text from PDF file:
var configuration = new Configuration("YourClientId", "YourClientSecret");
var parseApi = new ParseApi(configuration);
Initialize and instance of ParseApi by passing Configuration object as an argument.
Read the input PDF file from local drive and upload to cloud storage by calling UploadFile(...) method of UploadFileRequest class.
- TextOptions: Defines which file to extract text from.
- TextRequest: Sends the request to the cloud.
- parseApi.Text(): Returns the extracted text content.
