Converting docx template to pdf-CodePudding

I'm trying to programmatically populate a template (.docx file) and save it as a PDF. Is there a free library to do this? Or possibly another format to use for the template?

Would prefer not pay use interop methods, online services, or pay tons of money if possible.

I could use RDLC but I'd prefer to be able to modify the template with something like Word.

Using asp.net core 6.

You could try to use

Below is my test code which created the Word file.

using Word=Microsoft.Office.Interop.Word;

object missing = System.Reflection.Missing.Value;
            var wordApp = new Word.Application();
            wordApp.Visible = true;
            Microsoft.Office.Interop.Word.Document document= wordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing);
            object filename = @"C:\Users\Administrator\Desktop\temp1.docx";
            document.SaveAs2(ref filename);
            document.Close(ref missing, ref missing, ref missing);
            document = null;
            wordApp.Quit(ref missing, ref missing, ref missing);
            wordApp = null;

Further, you could modify it as per your requirements.

Since DocX is similar is some areas and features to Open Office Documents, then either Open office or Libre Office save as PDF is the second best option.

Libre/Open Office is cross platform and can be driven via command line, or Basic for office applications, thus an ideal candidate for conversions.

The list of command line options for Libre Office is currently at https://help.libreoffice.org/latest/en-US/text/shared/guide/start_parameters.html

To call writer you simply invoke along the lines of
```
 soffice --headless --convert-to pdf --outdir /folder/ /path/to/input.docx 
```
