Hello,
our clients reported the issue with the commas as thousand separators after merge. Attached is an example.
We use Spire.Office 7.7.2.
Regards
Document document = new Document();
document.LoadFromFile(@"MMTestTemplate_Calculations.docx");
string[] fieldNames = new string[] { "Investor_Sum1", "Investor_Sum2", "Investor_Sum3" };
string[] fieldValues = new string[] { "100000", "5000", "250.5" };
document.MailMerge.Execute(fieldNames, fieldValues);
document.IsUpdateFields = true;
document.SaveToFile(@"Spire_out.docx", Spire.Doc.FileFormat.Docx);
