Result could be improved by using properties

SensitivityOfComparison = 100; DetalisationLevel = DetalisationLevel.High;
But result could be not ideal because of lot of merged cells in document

Here is a result of using this property

and here is code sample

GroupDocs.Comparison.License lic = new License();
using (Comparer comparer = new Comparer(@"D:/Export 28_04_2021 19_05.xlsx"))
      CompareOptions options = new CompareOptions();
      options.SensitivityOfComparison = 100;
      options.DetalisationLevel = DetalisationLevel.High;
      comparer.Add(@"D:/Export 28_04_2021 18_57.xlsx");
      comparer.Compare(@"D:/output.xlsx", options);
