Also tried running it using the jsreport studio and it worked but not from the hosted version of the jsreport i have could it be a version issue? version on the site is version: 2.11.0

So i created a helper method to handle the template and make the request

public async Task<byte[]> RenderExcelAsync(string exceltemplate, object exceldata, string excelhelperFunctions = null)
        {
            try
            {
                Template excelt = new Template()
                {
                    Engine = Engine.Handlebars,
                    Recipe = Recipe.Xlsx,
                    Content = "{{{xlsxPrint}}}",
                    Xlsx = new Xlsx()
                    {
                        TemplateAsset = new Asset() { Encoding = "base64", Content = exceltemplate }
                    }
                };

                if (!string.IsNullOrEmpty(excelhelperFunctions))
                    excelt.Helpers = excelhelperFunctions;

                RenderRequest req = new RenderRequest()
                {
                    Template = excelt,
                    Data = exceldata
                };
                var result = await _service.RenderAsync(req);

                if (result.Content != null)
                {
                    using (var memoryStream = new MemoryStream())
                    {
                        result.Content.CopyTo(memoryStream);
                        return memoryStream.ToArray();
                    }
                }
                else
                    throw new ApplicationException("There was an error generating the PDF file.");
            }
            catch (Exception)
            {
                throw;
            }
        }
    }

it runs but instead of returning the rendered document it returns the template basically

I need some help when i try to render an xlsx template using the c# sdk it keeps returning the template instead of the rendered document
