Tutorial: Creating Powerful Comparisons with ComparisonOptions

In this tutorial, you’ll learn how to use the ComparisonOptions data structure in GroupDocs.Comparison Cloud API to configure comprehensive document comparison operations. This structure brings together multiple configuration elements to give you complete control over the comparison process.

Learning Objectives

  • Understand the ComparisonOptions structure and its components
  • Configure source and target document references
  • Implement detailed comparison settings
  • Specify output paths and formats
  • Create complete comparison operations for different document types

Prerequisites

  • GroupDocs.Comparison Cloud API credentials
  • Advanced understanding of document comparison concepts
  • Familiarity with JSON structures
  • Test documents for comparison operations

Understanding the ComparisonOptions Structure

The ComparisonOptions data structure defines a complete comparison operation, including source and target files, comparison settings, and output options.

{
  "SourceFile": {
    "FilePath": "string",
    "VersionId": "string",
    "StorageName": "string",
    "Password": "string"
  },
  "TargetFiles": [
    {
      "FilePath": "string",
      "VersionId": "string",
      "StorageName": "string",
      "Password": "string"
    }
  ],
  "Settings": {
    "GenerateSummaryPage": true,
    "ShowDeletedContent": true,
    "ShowInsertedContent": true,
    // ... additional settings ...
  },
  "ChangeType": "None",
  "OutputPath": "string"
}

Key components include:

ComponentDescription
SourceFileInformation about the source file (using the FileInfo structure)
TargetFilesAn array of information about target file(s) (using the FileInfo structure)
SettingsComparison process settings (using the Settings structure)
ChangeTypeChanges type (used only for Changes resource)
OutputPathPath to the resultant document

Implementing ComparisonOptions in Your Application

Step 1: Creating a Basic Comparison Configuration

Let’s start with a basic configuration that compares two documents with default settings:

Try it yourself

Create a basic ComparisonOptions object and use it to compare two simple documents.

Step 2: Configuring Multiple Target Files

ComparisonOptions supports comparing one source file with multiple target files:

Step 3: Implementing Detailed Comparison Settings

Now let’s enhance our comparison with detailed settings:

Troubleshooting Tip

If your comparison results don’t match expectations, verify that the Settings configuration is appropriate for your document types. Different document formats may require specific settings for optimal results.

Step 4: Working with Password-Protected Documents

Many business documents are password-protected. Here’s how to handle them:

Step 5: Specifying Output Options

Control how and where the comparison result is saved:

Step 6: Creating a Complete Comparison Operation

Finally, let’s put everything together for a comprehensive comparison operation:
