How to Compare Invoices Leave feedback

Sometimes you need to achieve maximum accuracy in comparing files. Suppose you have two versions of an important document and you need to find differences character-by-character or the opposite case, you need to compare the documents, but the details are not important to you, and you only need words that have changes. GroupDocs.Comparison provides the ability to compare documents with sensitivity settings

For example, there are two invoices in the DOCX format and you need to compare their contents with the maximum level of detail and comparison sensitivity.

Source Invoice			Target Invoice

GroupDocs.Comparison provides the ability to compare two files in DOCX format (or any other supported file formats with adjustment of detalization level and comparison sensitivity.

The following are the steps to compare two DOCX files with specific settings of detalization level and comparison sensitivity.

• Instantiate Comparer object with source document path or stream;
• Call Add method and specify target document path or stream;
• Instantiate CompareOptions object with desired SensitivityOfComparison and DetalisationLevel value;
• Call Compare method and pass CompareOptions object to method.

The following code samples demonstrate how to compare two DOCX files.

string sourceDocumentPath = @"Invoice_source.docx"; // NOTE: Put here actual path to source document
string targetDocumentPath = @"Invoice_target.docx"; // NOTE: Put here actual path to target document
string outputPath = @"Invoice_result.docx"; // NOTE: Put here actual path to result document

using (Comparer comparer = new Comparer(sourceDocumentPath))
{
    comparer.Add(targetDocumentPath);
    CompareOptions options = new CompareOptions
    {
        SensitivityOfComparison = 100,
        DetalisationLevel = DetalisationLevel.High
    };
    comparer.Compare(outputPath, options);
}

As a result, we get a DOCX file where the deleted elements are marked in red, the added – in blue, and the modified – in green
