Change PDF, Word in C++

The task of editing a document programmatically in C++ is the task of modifying elements in the document tree. It is also known as the 'DOM' - the programming model for interacting with document elements and their properties.

Editing features for complex data structures are inseparable from the advanced search function. To ensure the highest level of flexibility, our library provides C++ developers with Regex search functionality. This approach expands the possibilities to edit text, allowing the use of templates for dynamic content modification.
