OfficeIMO.Word - Word documents for .NET

👁 nuget version
👁 nuget downloads

OfficeIMO.Word is the main Word document package in the OfficeIMO family. It creates, edits, inspects, and saves .docx files without COM automation and without Microsoft Office installed.

If OfficeIMO saves you time, please consider supporting the work through GitHub Sponsors or PayPal. PowerShell users should use PSWriteOffice for the PowerShell-facing experience.

Install

dotnet add package OfficeIMO.Word

Quick start

using OfficeIMO.Word;

using var document = WordDocument.Create("report.docx");

document.AddParagraph("Quarterly report").Style = WordParagraphStyles.Heading1;
document.AddParagraph("Created with OfficeIMO.Word.");

var table = document.AddTable(2, 2, WordTableStyle.TableGrid);
table.Rows[0].Cells[0].Paragraphs[0].Text = "Area";
table.Rows[0].Cells[1].Paragraphs[0].Text = "Status";
table.Rows[1].Cells[0].Paragraphs[0].Text = "Documents";
table.Rows[1].Cells[1].Paragraphs[0].Text = "Generated";
table.RepeatHeaderRowAtTheTopOfEachPage = true;
table.Style = WordTableStyle.TableGrid;

document.Save();

What it does

• Creates, loads, edits, saves, and appends .docx documents.
• Works with paragraphs, runs, styles, sections, headers, footers, page numbers, tables, images, hyperlinks, bookmarks, fields, footnotes, endnotes, content controls, charts, shapes, and document protection.
• Keeps Office automation out of the runtime path, making it suitable for services, scheduled jobs, CI, desktop apps, and automation hosts.
• Provides fluent helpers for common authoring flows while keeping the lower-level Word object model available.
• Uses OfficeIMO.Drawing for shared color and image metadata support.

Examples

The quick start shows the smallest useful document. These examples show the kinds of document work that belong in OfficeIMO.Word itself.

Paragraphs and runs

var paragraph = document.AddParagraph("Status: ");
paragraph.AddText("Approved").Bold = true;
paragraph.AddText(" on ");
paragraph.AddText(DateTime.Today.ToString("yyyy-MM-dd")).Italic = true;

Tables with structure

var table = document.AddTable(3, 3);
table.Rows[0].Cells[0].Paragraphs[0].Text = "Area";
table.Rows[0].Cells[1].Paragraphs[0].Text = "Owner";
table.Rows[0].Cells[2].Paragraphs[0].Text = "Status";
table.RepeatHeaderRowAtTheTopOfEachPage = true;
table.Style = WordTableStyle.TableGrid;

table.Rows[1].Cells[0].Paragraphs[0].Text = "Documents";
table.Rows[1].Cells[1].Paragraphs[0].Text = "Operations";
table.Rows[1].Cells[2].Paragraphs[0].Text = "Ready";

table.MergeCells(rowIndex: 2, columnIndex: 0, rowSpan: 1, colSpan: 3);
table.Rows[2].Cells[0].Paragraphs[0].Text = "Generated by OfficeIMO.Word";

Headers and footers

document.HeaderDefaultOrCreate.AddParagraph("Internal report");
document.FooterDefaultOrCreate.AddParagraph()
 .AddText("Page ")
 .AddPageNumber();

Images

var paragraph = document.AddParagraph();
paragraph.AddImage("logo.png", width: 160, height: 64);

Hyperlinks and bookmarks

document.AddParagraph("Jump target").AddBookmark("target-section");
document.AddParagraph()
 .AddHyperLink("Open project site", new Uri("https://github.com/EvotecIT/OfficeIMO"));
document.AddParagraph()
 .AddHyperLink("Jump inside document", "target-section", addStyle: true);

Fields and table of contents

document.AddParagraph("Chapter 1").Style = WordParagraphStyles.Heading1;
document.AddParagraph("Section 1.1").Style = WordParagraphStyles.Heading2;
document.Paragraphs[0].AddField(WordFieldType.TOC);

Mail merge fields

var merge = document.AddParagraph();
merge.AddText("Customer: ");
merge.AddField(new WordFieldBuilder(WordFieldType.MergeField)
 .AddInstruction("CustomerName"));

var totalField = new WordFieldBuilder(WordFieldType.MergeField)
 .AddInstruction("OrderTotal")
 .SetFormat(WordFieldFormat.Numeric);
merge.AddField(totalField);

Content controls

document.FillContentControlValues(new Dictionary<string, object?> {
 ["Name"] = "Ada Lovelace",
 ["Approved"] = true,
 ["DueDate"] = DateTime.Today
});

Dictionary<string, object?> values = document.ExtractContentControlValues();
document.ValidateContentControlValues(values).EnsureValid();

Protection

using DocumentFormat.OpenXml.Wordprocessing;

document.Settings.ProtectionPassword = "owner-password";
document.Settings.ProtectionType = DocumentProtectionValues.ReadOnly;

Convert with adjacent packages

using OfficeIMO.Word.Html;
using OfficeIMO.Word.Markdown;
using OfficeIMO.Word.Pdf;

string html = document.ToHtml(new WordToHtmlOptions { IncludeDefaultCss = true });
string markdown = document.ToMarkdown(new WordToMarkdownOptions());
document.SaveAsPdf("report.pdf");

Adjacent packages

OfficeIMO.Word owns the Word model. Conversion and export packages stay separate so consumers only take the dependencies they need:

Boundaries

• PowerShell examples and cmdlets belong in PSWriteOffice, not this package README.
• Long capability inventories and roadmap notes belong in focused docs under Docs/.
• PDF layout behavior belongs in OfficeIMO.Word.Pdf and OfficeIMO.Pdf.

Targets and license

• Targets: netstandard2.0, net8.0, net10.0; net472 is included when building on Windows.
• License: MIT.
• Repository: EvotecIT/OfficeIMO
