Highlight Highest and Lowest Value in Excel Using Java

As introduced in my previous article, the Free Spire.XLS for Java is able to highlight the duplicate and unique values in Excel . Now this article will give another example of how to use it to highlight the highest and lowest value in a cell rang.

Import the jar dependency
Method 1: Download the Free Spire.XLS for Java and unzip it, then add the Spire.Xls.jar file to your project as dependency.

Method 2: Directly add the jar dependency to maven project by adding the following configurations to the pom.xml.

<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <name>e-iceblue</name>
            <url>http://repo.e-iceblue.com/nexus/content/groups/public/</url>
        </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.xls.free</artifactId>
        <version>3.9.1</version>
    </dependency>
</dependencies>

Sample Code

import com.spire.xls.*;

import java.awt.*;

public class HighlightTopBottom {

    public static void main(String[] args) {

        //Create a Workbook object
        Workbook workbook = new Workbook();

        //Load the sample Excel file
        workbook.loadFromFile("test.xlsx");

        //Get the first worksheet
        Worksheet sheet = workbook.getWorksheets().get(0);

        //Apply conditional formatting to range "D1:D9" to highlight the highest value
        ConditionalFormatWrapper format1 = sheet.getCellRange("D1:D9").getConditionalFormats().addCondition();
        format1.setFormatType(ConditionalFormatType.TopBottom);
        format1.getTopBottom().setType(TopBottomType.Top);
        format1.getTopBottom().setRank(1);
        format1.setBackColor(Color.red);

        //Apply conditional formatting to range "D1:D9" to highlight the lowest value
        ConditionalFormatWrapper format2 = sheet.getCellRange("D1:D9").getConditionalFormats().addCondition();
        format2.setFormatType(ConditionalFormatType.TopBottom);
        format2.getTopBottom().setType(TopBottomType.Bottom);
        format2.getTopBottom().setRank(1);
        format2.setBackColor(Color.CYAN);

        //Save the document
        workbook.saveToFile("output/HighestLowestValue.xlsx", ExcelVersion.Version2016);
    }
}

Output
