I am developing reports in Excel using Syncfusion xlsio for asp.net.

I would like to know how to configure the number format when change the regional Setting, example in es-ES the decimal symbol is the comma (,) but in en-US is the point (.)

Another example in es-ES have 1200,50 but in en-US this number change to 120050

Hi Nestor Alvarado Namen,

Thank you for using Syncfusion products.

By default, XlsIO supports cell number formatting for US culture settings. If a cell is assigned with a value 1200.50 with its number format as "###.#0", then the output will be as below.

 * en-US - 1200.50
 * es-ES -  1200,50
If the provided number format in not valid for the available culture settings, then a default format will be displayed in excel file. So, it is not necessary to change the number format in XlsIO, instead you can fix to US culture settings.

Kindly get back to us if you need more clarification on this along with the scenario you are trying to use.

Hi Johnson

My question is this, We have a multilanguage web application in asp.net using globalization culture, so we are using the XlsIo for generate the excel report for the users. Now when switching from one language to another, the value of the numbers change.

Example in a report for spanish shown 1200,52 but when the report is generate with a login in english shown 120052, where it is not the same value.

Hi Nestor,


Thank you for updating us.


Your machine culture seems to be in Spanish and you are trying to import data and generate the file in US culture In that case, the output is similar to the one you have shared. This can be resolved by setting decimal separator to the required culture. This can be achieved by the highlighted line in the following code snippets.


        private void btnCreateExcel_Click(object sender, System.EventArgs e)


            ExcelEngine excelEngine = new ExcelEngine();


            IApplication application = excelEngine.Excel;

            application.DefaultVersion = ExcelVersion.Excel97to2003;


            IWorkbook workbook = application.Workbooks.Open(@"../../Data/Sample.xls", ExcelOpenType.Automatic);

            IWorksheet sheet = workbook.Worksheets[0];


            //US Culture

            System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");


            ////Spanish Culture

            //System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("es-ES");


            application.DecimalSeparator = System.Threading.Thread.CurrentThread.CurrentCulture.NumberFormat.NumberDecimalSeparator;


            sheet.ImportDataTable(GetDataTable(), true, 1, 1, false);


            workbook.Version = ExcelVersion.Excel97to2003;

            string fileName = @"../../Output/Output.xls";












        private DataTable GetDataTable()


            DataTable dt = new DataTable("Data");



            DataRow dr1 = dt.NewRow();

            dr1["PRECIO"] = 1253.53;



            dt.Rows.Add(dt.NewRow()["PRECIO"] = 1253.53);

            dt.Rows.Add(dt.NewRow()["PRECIO"] = 2848.94);

            dt.Rows.Add(dt.NewRow()["PRECIO"] = 3112.01);

            dt.Rows.Add(dt.NewRow()["PRECIO"] = 3219.3);

            dt.Rows.Add(dt.NewRow()["PRECIO"] = 784.77);

            dt.Rows.Add(dt.NewRow()["PRECIO"] = 1139.58);

            dt.Rows.Add(dt.NewRow()["PRECIO"] = 1271.87);

            dt.Rows.Add(dt.NewRow()["PRECIO"] = 723.77);


            return dt;




Kindly try this approach and get back to us if the issue is resolved.

Hi Nestor,


Thank you for updating us.


The issue you encountered occurs in versions prior to 12.1. if your working version is beyond 12.1, we strongly recommend you to upgrade to the latest version 12.2 which has more features and enhancements.
