Hi,

if you are working with VB.NET DOCX file format, you might also check this C# / VB.NET Word library that works without MS Word installed and has its own .NET Word mail merge functionality, so you can merge DataTable directly without a need to export it to CSV first:

' Use the component in free mode.
ComponentInfo.SetLicense("FREE-LIMITED-KEY")
 
' Define DataTable with two columns: 'Name' and 'Surname', and fill it with some data.
' You don't have to do this if you already have a DataTable instance.
Dim dataTable = New DataTable("People")
dataTable.Columns.Add(New DataColumn("Name", GetType(String)))
dataTable.Columns.Add(New DataColumn("Surname", GetType(String)))
dataTable.Rows.Add("John", "Doe")
dataTable.Rows.Add("Fred", "Nurk")
dataTable.Rows.Add("Hans", "Meier")
dataTable.Rows.Add("Ivan", "Horvat")
 
' Create and save a template document. 
' You don't have to do this if you already have a template document.
' This code is only provided as a reference how template document should look like.
Dim document = New DocumentModel()
document.Sections.Add(
  New Section(document,
    New Table(document,
      New TableRow(document,
        New TableCell(document,
          New Paragraph(document, "Name")),
        New TableCell(document,
          New Paragraph(document, "Surname"))),
      New TableRow(document,
        New TableCell(document,
          New Paragraph(document,
            New Field(document, FieldType.MergeField, "RangeStart:People"),
            New Field(document, FieldType.MergeField, "Name"))),
        New TableCell(document,
          New Paragraph(document,
            New Field(document, FieldType.MergeField, "Surname"),
            New Field(document, FieldType.MergeField, "RangeEnd:People")))))))
document.Save("TemplateDocument.docx", SaveOptions.DocxDefault)
 
' Load a template document.
document = DocumentModel.Load("TemplateDocument.docx", LoadOptions.DocxDefault)
 
' Mail merge template document with DataTable.
' Important: DataTable.TableName and RangeStart/RangeEnd merge field names must match.
document.MailMerge.ExecuteRange(dataTable)
 
' Save the mail merged document.
document.Save("Document.docx", SaveOptions.DocxDefault)
