How can I enter a new line in an Excel cell? I know in Excel there is "Alt + Enter" combination, but can I do it in code?

You can enter a new line in a cell by using the character that has the 0x0A=10 code to separate the words. You also have to set the wrap property for the cell format.

ExcelStyle styleWrap = new ExcelStyle();
styleWrap.setWrap(true);
xlsWorksheet.easy_getExcelTable().easy_getCell("A1").setStyle(styleWrap);
