    }
}

Implementation Guide

Get Possible Conversions

Overview: This feature helps you determine all potential formats a source document can be converted into.

Step 1: Initialize the Converter

Create an instance of Converter with your document’s path:

import com.groupdocs.conversion.Converter;

Converter converter = new Converter("YOUR_DOCUMENT_DIRECTORY/sample.docx");

Step 2: Retrieve Possible Conversions

Use getPossibleConversions() to fetch available formats:

import com.groupdocs.conversion.contracts.PossibleConversions;

// Obtain possible conversions.
PossibleConversions conversions = converter.getPossibleConversions();

Step 3: Display Conversion Options

Print the source file type and potential target formats:

System.out.print(String.format("%s is of type %s and could be converted to:\
