Excel worksheet protection
The following example shows how you can protect a worksheet.
Note that specifying advanced settings like sheet password is supported only in XLSX and XLS and allowing some objects to be editable is supported only for XLSX file format.

import com.gembox.spreadsheet.*;
class Program {
public static void main(String[] args) throws java.io.IOException {
// If using Professional version, put your serial key below.
SpreadsheetInfo.setLicense("FREE-LIMITED-KEY");
ExcelFile workbook = new ExcelFile();
ExcelWorksheet worksheet = workbook.addWorksheet("Sheet Protection");
worksheet.getCell(0, 2).setValue("Only cells from A1 to A10 are editable.");
for (int i = 0; i < 10; i++) {
ExcelCell cell = worksheet.getCell(i, 0);
cell.setValue(i);
cell.getStyle().setLocked(false);
}
worksheet.setProtected(true);
WorksheetProtection protectionSettings = worksheet.getProtectionSettings();
worksheet.getCell(3, 2).setValue("Sheet password is 123 (only supported for XLSX and XLS file format).");
protectionSettings.setPassword("123");
// Supported only for XLSX file format.
worksheet.getCell(2, 2).setValue("Inserting columns is allowed (only supported for XLSX file format).");
protectionSettings.setAllowInsertingColumns(true);
workbook.save("Sheet Protection.%OutputFileType%");
}
}
