Find and Replace Data in a Worksheet in Excel
The Worksheet.findAllString() method provided by Spire.XLS for Java can help you find the cells containing specific text in Excel documents. Once found, you can conveniently replace these values with new ones using the CellRange.setText() method. The steps are as follows:
- Create an instance of Workbook class.
- Load an Excel file using Workbook.loadFromFile() method.
- Get the desired worksheet using Workbook.getWorksheets().get() method.
- Find the specific value in the worksheet using Worksheet.findAllString() method and replace the value of the cell with another value using CellRange.setText() method.
- Set a background for the cell so you can easily find the updated cells using CellRange. getStyle().setColor() method.
- Save the result file using Workbook.saveToFile() method.
- Java
import com.spire.xls.CellRange;
import com.spire.xls.ExcelVersion;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
import java.awt.Color;
public class ReplaceData {
public static void main(String[] args) {
// Initialize an instance of the Workbook class
Workbook workbook = new Workbook();
// Load an Excel file
workbook.loadFromFile("Test.xlsx");
// Get the first worksheet
Worksheet worksheet = workbook.getWorksheets().get(0);
// Find the cells with the specific string value "Total" in the worksheet
CellRange[] cells = worksheet.findAllString("Total", true, true);
// Iterate through the found cells
for (CellRange cell : cells) {
// Replace the value of the cell with another value
cell.setText("Sum");
// Set a background color for the cell
cell.getStyle().setColor(Color.YELLOW);
}
// Save the result file to a specific location
workbook.saveToFile("ReplaceDataInWorksheet.xlsx", ExcelVersion.Version2016);
workbook.dispose();
}
}
Find and Replace Data in a Specific Cell Range in Excel
To replace data within a specific range of cells, you can utilize the CellRange.findAllString() method to locate cells within the range that contain the desired values. Then, use the CellRange.setText() method to replace the cell value with a new value. The detailed steps are as follows:
- Create an instance of Workbook class.
- Load an Excel file using Workbook.loadFromFile() method.
- Get the desired worksheet using Workbook.getWorksheets().get() method.
- Get a specific cell range using Worksheet.getCellRange() method.
- Find the cells with the specific value in the cell range using CellRange.findAllString() method.
- Iterate through the found cells
- Replace the value of the cell with another value using CellRange setText() method.
- Set a background for the cell so you can easily find the updated cells using the CellRange. getStyle().setColor() method.
- Save the result file using Workbook.saveToFile() method.
- Java
import com.spire.xls.CellRange;
import com.spire.xls.ExcelVersion;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
import java.awt.Color;
public class ReplaceDataInCellRange {
public static void main(String[] args) {
// Initialize an instance of the Workbook class
Workbook workbook = new Workbook();
// Load an Excel file
workbook.loadFromFile("Test.xlsx");
// Get the first worksheet
Worksheet worksheet = workbook.getWorksheets().get(0);
// Get a specific cell range
CellRange range = worksheet.getCellRange("A1:C12");
// Find the cells with the specific value "Total" in the cell range
CellRange[] cells = range.findAllString("Total", true, true);
// Iterate through the found cells
for (CellRange cell : cells) {
// Replace the value of the cell with another value
cell.setText("Sum");
// Set a background color for the cell
cell.getStyle().setColor(Color.YELLOW);
}
// Save the result file to a specific location
workbook.saveToFile("ReplaceDataInCellRange.xlsx", ExcelVersion.Version2016);
workbook.dispose();
}
}
