I am developing a Web API project in Asp.net core 2.0. I am in need of a library or way to create Word document. I have searched an tried NPOI and DocX. Both are not as good as
At first glance, the below link can help somehow:

Anyway, about DOCX - Word Document using Open XML SDK by Microsoft - you can install Open XML SDK into your solution using the version 2.8.1. It´s all free.
Documentation avaliable at:
On GIT => https://github.com/OfficeDev/Open-XML-SDK ;
On MSDN => https://docs.microsoft.com/en-us/office/open-xml/open-xml-sdk
ps: the MSDN documentation is all about the version SDK 2.5 instead of 2.8.1, but as explained in the GIT link there is no substancial changes.
Anyway to use it in a Web APP CORE 2.0 you can do the follow:
Reference the below namespaces within your controller:
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
If you just want to save it in a folder locally do something like:
public static void CreateWordprocessingDocument(string filepath)
{
// Create a document by supplying the filepath.
using (WordprocessingDocument wordDocument =
WordprocessingDocument.Create(filepath, WordprocessingDocumentType.Document))
{
// Add a main document part.
MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();
// Create the document structure and add some text.
mainPart.Document = new Document();
Body body = mainPart.Document.AppendChild(new Body());
Paragraph para = body.AppendChild(new Paragraph());
Run run = para.AppendChild(new Run());
run.AppendChild(new Text("Create text in body - CreateWordprocessingDocument"));
}
}
and call it like:
public IActionResult GenerateDocx()
{
string filePath = @"c:\word\Invoice.docx";
CreateWordprocessingDocument(filePath);
}
If you want to generate a docx to be saved into a users computer from their browsers, after hitting a link, do something like:
// GET verb
public IActionResult GenerateDocxBrowser()
{
// open xml sdk - docx
using (MemoryStream mem = new MemoryStream())
{
using (WordprocessingDocument wordDoc = WordprocessingDocument.Create(mem, DocumentFormat.OpenXml.WordprocessingDocumentType.Document, true))
{
wordDoc.AddMainDocumentPart();
// siga a ordem
Document doc = new Document();
Body body = new Body();
// 1 paragrafo
Paragraph para = new Paragraph();
ParagraphProperties paragraphProperties1 = new ParagraphProperties();
ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "Normal" };
Justification justification1 = new Justification() { Val = JustificationValues.Center };
ParagraphMarkRunProperties paragraphMarkRunProperties1 = new ParagraphMarkRunProperties();
paragraphProperties1.Append(paragraphStyleId1);
paragraphProperties1.Append(justification1);
paragraphProperties1.Append(paragraphMarkRunProperties1);
Run run = new Run();
RunProperties runProperties1 = new RunProperties();
Text text = new Text() { Text = "The OpenXML SDK rocks!" };
// siga a ordem
run.Append(runProperties1);
run.Append(text);
para.Append(paragraphProperties1);
para.Append(run);
// 2 paragrafo
Paragraph para2 = new Paragraph();
ParagraphProperties paragraphProperties2 = new ParagraphProperties();
ParagraphStyleId paragraphStyleId2 = new ParagraphStyleId() { Val = "Normal" };
Justification justification2 = new Justification() { Val = JustificationValues.Start };
ParagraphMarkRunProperties paragraphMarkRunProperties2 = new ParagraphMarkRunProperties();
paragraphProperties2.Append(paragraphStyleId2);
paragraphProperties2.Append(justification2);
paragraphProperties2.Append(paragraphMarkRunProperties2);
Run run2 = new Run();
RunProperties runProperties3 = new RunProperties();
Text text2 = new Text();
text2.Text = "Teste aqui";
run2.AppendChild(new Break());
run2.AppendChild(new Text("Hello"));
run2.AppendChild(new Break());
run2.AppendChild(new Text("world"));
para2.Append(paragraphProperties2);
para2.Append(run2);
// todos os 2 paragrafos no main body
body.Append(para);
body.Append(para2);
doc.Append(body);
wordDoc.MainDocumentPart.Document = doc;
wordDoc.Close();
}
return File(mem.ToArray(), "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "ABC.docx");
}
}
the above code even shows how to use the most important objects: body, paragraphs, runs and text. Remember to follow this order always!
