Compare Documents

Comparison features

Information about Changes detection algorithms used by GroupDocs.Comparison allows to detect changes in different document parts and blocks:

• Text blocks - paragraphs, words and characters;
• Tables;
• Images;
• Shapes etc.

For better visual separation of detected changes added, modified or deleted document parts are highlighted with different colors:

• Added – blue 
• Modified – green
• Style – green
• Deleted – red

Style coloring scheme can be customized if needed, changed text blocks can be marked with different formatting - italic, bold, underlined, strikethrough etc.

 Here are simple steps to compare two documents:

• Instantiate Comparer object with source document path or stream;
• Call Add method and specify target document path or stream.
• Call Compare method.

The following code sample shows the simplest case of documents comparison using couple lines of code.
