Extract right-to-left data from documents in C# and .NET
Processing RTL documents is a common need for international businesses, government agencies, educational institutions, and many other organizations. Virtual assistants, automated translation systems, search engines, and archival storage systems all require accurate data extraction with support for RTL languages. In this article, we'll discuss how to easily implement this task using C# and .NET, using the popular SDK SautinSoft Document.NET.
Many documents, especially those in Arabic, Hebrew, and other right-to-left (RTL) languages, require a special approach during processing. The standards and structures of such documents may differ from those typical for left-to-left (LTR) text.
Tasks related to extracting text and data from RTL documents:
- Automating the processing of large volumes of documents;
- Implementing a search and analysis system;
- Migrating data between systems supporting different languages and text directions;
- Ensuring the accurate operation of OCR and recognition systems, where text directionality is important.
Without proper processing, there is a risk of losing important data or misinterpreting the content.
