The method insertSpreadsheet() returns a com.sun.star.sheet.XSpreadsheet interface. This interface is passed to the method below, which shows how to access and modify the content and formatting of single cells. The interface com.sun.star.sheet.XSpreadsheet returned by insertSpreadsheet() is derived from com.sun.star.table.XCellRange. By working with it, cells can be accessed immediately using getCellByPosition():

 void cellWork(XSpreadsheet xRange) {
     com.sun.star.beans.XPropertySet xPropSet = null;
     com.sun.star.table.XCell xCell = null;
     // Access and modify a VALUE CELL
     xCell = xRange.getCellByPosition(0, 0);
     // Set cell value.
     // Get cell value.
     double nDblValue = xCell.getValue() * 2;
     xRange.getCellByPosition(0, 1).setValue(nDblValue);
     // Create a FORMULA CELL
     xCell = xRange.getCellByPosition(0, 2);
     // Set formula string.
     // Get error type.
     boolean bValid = (xCell.getError() == 0);
     // Get formula string.
     String aText = "The formula " + xCell.getFormula() + " is ";
     aText += bValid ? "valid." : "erroneous.";
     // Insert a TEXT CELL using the XText interface
     xCell = xRange.getCellByPosition(0, 3);
     com.sun.star.text.XText xCellText = (com.sun.star.text.XText)
         UnoRuntime.queryInterface(com.sun.star.text.XText.class, xCell);
     com.sun.star.text.XTextCursor xTextCursor = xCellText.createTextCursor();
     xCellText.insertString(xTextCursor, aText, false);
     // set the cell's background color
     Integer bg_color = new Integer(0x008000);
     xPropSet = (com.sun.star.beans.XPropertySet)
     xPropSet.setPropertyValue("CellBackColor", bg_color);
     // set the cell's foreground (text) color
     Integer fg_color = new Integer(0x800000);
     xPropSet = (com.sun.star.beans.XPropertySet) UnoRuntime.queryInterface(com.sun.star.beans.XPropertySet.class,
     xPropSet.setPropertyValue("CharColor", fg_color);

Running an example showing how to find out which properties an object provides (with an com.sun.star.table.XCell object instead of mxDocCursor), one gets for example the following properties (OpenOffice.org 2.4):
