Open LEX File

LEX extension files are a type of file developed to store lexicon data created by the Linguistic Library.

Linguistic Library is an Adobe Integrated Development Kit or IDE used to add linguistic services, such as spelling and grammar checkers, to Adobe products.

The Linguistic Library itself is an installable plugin for Adobe products, containing information and resources related to the development of software components (plugins) for the Linguistic Library.

With the Linguistic Library SDK downloaded and installed, you can write add-on components to extend the functionality of the Linguistic Library and provide additional linguistic services to various Adobe products.

The LEX file contains the shared lexicons, or words and their syntax, for a particular language.

Similarly, LEX files are used to store language-specific data for document validation, specifically in Adobe products.

On the other hand, LEX extension files can be used in several Adobe products, such as Acrobat, Photoshop, InDesign and Illustrator, thus making it quite a versatile format, despite being proprietary.

It is important to know that Adobe no longer supports the Linguistic Library DLL.
