I was also running into this issue and this was my solution.

Steps:

1. Create workbook
2. Create spreadsheet
3. Create row
4. Create/Set font to "Arial"
5. Create/Set style with font
6. Create/Set cell with value and style
7. autoSizeColumn
8. Create File

Code:

// initialize objects
XSSFWorkbook workbook = new XSSFWorkbook(); 
XSSFSheet spreadsheet = workbook.createSheet(sheetName);
XSSFRow row = spreadsheet.createRow(0);
XSSFCell cell;

// font/style
XSSFFont font = workbook.createFont();
font.setFontName("Arial");
XSSFCellStyle style = workbook.createCellStyle();
style.setFont(font);

// create/set cell & style
cell = row.createCell(0);
cell.setCellValue("New Cell");
cell.setCellStyle(style);

// auto size
spreadsheet.autoSizeColumn(0);

// create file
File aFile = new File("Your Filename");
FileOutputStream out = new FileOutputStream(aFile);
workbook.write(out);

Just to make an answer out of my comment. The rows couldn't size properly because Java was unaware of the font you were trying to use this link should help if you want to install new fonts into Java so you could use something fancier. It also has the list of default fonts that Java knows.

Glad this helped and you got your issue solved!
