Hi,
Thanks for your posting and using Aspose.Cells for .NET.
Please use the following code to apply your desired currency formatting. Please also download and use the latest version: Aspose.Cells
for .NET v7.3.4.2
I have attached the output xlsx file generated using the following code. Please also see the screenshot for your reference.
C#
Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];
Style style = workbook.CreateStyle();
style.Custom = “"$"#,##0.00”;
style.Custom = “"$"#,##0.00”;
//Access colum A
Column column = worksheet.Cells.Columns[0];
StyleFlag flag = new StyleFlag();
flag.NumberFormat = true;
column.ApplyStyle(style, flag);
//Test values
worksheet.Cells[“A1”].PutValue(1);
worksheet.Cells[“A2”].PutValue(2);
worksheet.Cells[“A3”].PutValue(3);
workbook.Save(“output.xlsx”, SaveFormat.Xlsx);
