Excel styles and formatting in Java

GemBox.Spreadsheet for Java has been retired

Using GemBox.Spreadsheet you can style and format an Excel file in Java. You can set custom number formatting, cell styles (alignment, indentation, rotation, borders, shading, protection, text wrapping, shrinking, etc.) and font formatting (size, color, font type, italic and strikeout properties, different levels of boldness, underlining, subscript and superscript).

Following example shows how to set different style-specific properties on Excel rows, columns and cells.
