Here is an Excel API for Java that you could use:

ExcelFile workbook = ExcelFile.load("input.xlsx");
ExcelWorksheet worksheet = workbook.getWorksheet(0);

int rowsCount = worksheet.getRows().size();
int columnsCount = worksheet.calculateMaxUsedColumns();

String[][] rowData = new String[rowsCount][columnsCount];
String[] columnNames = new String[columnsCount];

for (int row = 0; row < rowsCount; row++) {
for (int column = 0; column < columnsCount; column++) {

ExcelCell cell = worksheet.getCell(row, column);
String value = cell.getValue().toString();
if (row == 0)
columnNames[column] = value;
else
rowData[row - 1][column] = value;

}
}

JTable table = new JTable(rowData, columnNames);
// Use 'table' object with your JFrame...

Basically, you could create a JTable by reading Excel file from Java.

Solution 1

you should use the Apache POI library[^]. That one can "translate" MS Office documents into Java readable stuff.

They have a part POI-HSSF and POI-XSSF in there that is responsable for Excel Documents: http://poi.apache.org/spreadsheet/index.html[^].
Please check out the menu on the left side there, they have several tutorials, Examples and much more to get into it.

okey, what you know the code or script that is used to JTable in Java JFrame Form?

No. Also the code depends on what you're doing there.
There no such thing as a "genetic super implementation".

But check out the Tutorial they have and you will sure get a good idea on how to do your application.
