Apply percentage number format to worksheet cells in Java

I checked the doc style - Aspose.Cells for Java - API Reference
and I didn’t find the support for the format like “0.0%” or “0.000%”

@larryyu1,

These are some selected (built-in) pattern supported when you use Style.setNumber() method. For your needs, you may use Style.setCustom() method to implement your desired formats (“0.0%” or “0.000%”). See the sample code segment for your reference.
e.g.
Sample code:

Workbook workbook = new Workbook();
Worksheet worksheet = workbook.getWorksheets().get(0);
Cell cell = worksheet.getCells().get("A1");
cell.putValue(.75);
Style style = cell.getStyle();
style.setCustom("0.0%");
cell.setStyle(style);
workbook.save("out1.xlsx");

Hope, this helps a bit.

it works.thank you for your quick reply.
