OfficeIMO is a family of COM-free .NET libraries for creating, reading, editing, converting, and exporting Office and document formats. It runs in services, desktop applications, build agents, containers, and automation hosts without Microsoft Office, Excel, PowerPoint, Visio, or LibreOffice automation.
This is not one facade over a collection of unrelated document libraries. OfficeIMO owns its OneNote, PDF, Markdown, RTF, OpenDocument, AsciiDoc, LaTeX, OPML, DocBook, CSV, EPUB, ZIP, drawing, Apple iWork source, legacy Word `.doc`, legacy Excel `.xls`, and legacy PowerPoint `.ppt`/`.pot`/`.pps` implementations. Word, Excel, and PowerPoint use the Open XML SDK for package mechanics; HTML exposes owned document and provider contracts while retaining AngleSharp for parsing and CSS execution. Converters compose the same first-party object models used by the native packages and return diagnostics when a target format cannot carry everything from the source.
Applications should keep OfficeIMO packages on the same coordinated version. Converters compose package-owned document models and expose result-bearing APIs when callers need fidelity diagnostics.
For existing Windows x64 applications that import through ODBC, [OfficeIMO.Odbc](OfficeIMO.Odbc/README.md) exposes bounded `.xlsx` workbook snapshots as read-only SQL tables. It is built and deployed separately from the .NET document packages.
Upgrading an existing application? The [OfficeIMO migration guide](MIGRATION.md) covers package, API, and behavior changes across every format. Release history and downloadable artifacts are published through [GitHub Releases](https://github.com/EvotecIT/OfficeIMO/releases).
If OfficeIMO saves you time, please consider supporting the work through [GitHub Sponsors](https://github.com/sponsors/PrzemyslawKlys) or [PayPal](https://paypal.me/PrzemyslawKlys). PowerShell users should start with [PSWriteOffice](https://github.com/EvotecIT/OfficeIMO/tree/master/PowerShell/PSWriteOffice).

## Dependency model
OfficeIMO keeps document engines first-party and optional integrations isolated. The table calls out direct non-OfficeIMO runtime dependencies that matter to package selection; Microsoft/BCL compatibility packages are still used where older target frameworks need platform APIs.
| Package family | Direct external runtime dependency | What OfficeIMO owns |
| --- | --- | --- |

The checkboxes describe the exact level of support: authoring, editing, reading, preserving, inspecting, converting, or exporting. A checked inspection or preservation item is not presented as full authoring support.
## OfficeIMO Studio
[OfficeIMO Studio](https://officeimo.com/studio/) puts the OfficeIMO engines in an app: read, search, mark up and fill PDFs, organize pages, make scans searchable, convert Office documents to PDF, and protect and sign the result. Documents are processed on your own device; connecting the document assistant to a model is optional.
- **Windows and Linux:** the desktop workspace, from the [Microsoft Store](https://apps.microsoft.com/detail/xp9m6j7hvm2hz0) or as a signed MSI, Debian package or portable ZIP for x64 and Arm64 from [GitHub Releases](https://github.com/EvotecIT/OfficeIMO/releases). It adds comment threads, redaction, content editing, form authoring, conversion from PDF, comparison and a document assistant. See the [Studio README](OfficeIMO.Studio/README.md).
- **Mac, iPad and iPhone:** native apps on the same engine, in development, with system document handling, Apple Pencil markup, the document camera, on-device text recognition with Vision, and Shortcuts. See the [Apple app README](Apple/OfficeIMOStudio/README.md).
The [feature table on the Studio page](https://officeimo.com/studio/#features) shows what Studio does on each system and what is planned.

</p>
The [OfficeIMO command-line tool](OfficeIMO.Tool/README.md) runs the same conversions, extraction and workflows from scripts, and serves them to AI agents over MCP.
## OfficeIMO for AI agents
Claude Code, Codex, VS Code with GitHub Copilot, Cursor and other MCP clients use OfficeIMO to inspect, search, fetch and convert local Word, Excel, PowerPoint, PDF and mail files, and to make separate PDF outputs. The [OfficeIMO Document Tools plugin](.agents/plugins/officeimo-document-tools/README.md) adds two Agent Skills and the MCP server, which runs on your computer and opens only the folders you allow:
```text
claude plugin marketplace add EvotecIT/OfficeIMO
codex plugin marketplace add EvotecIT/OfficeIMO --ref master --sparse .agents/plugins
```
The [AI agents page](https://officeimo.com/agents/) has one-click installation for VS Code and Cursor, the configuration for other clients, every tool the server provides, and the directories that list OfficeIMO.

- [x] Focused switches for PDF, presentation, OpenDocument, and Visio showcase artifacts
- [x] Machine-readable summaries and browsable galleries for reviewing generated output
_Dependency footprint:_ project references to the OfficeIMO libraries being demonstrated; this executable documentation project is not a runtime package.
## Conversion graph
The native packages are the source of truth. Adapter packages connect them without creating a second parser or document model.

Fixed-layout PDF import is necessarily semantic rather than visually lossless. Result-bearing APIs expose warnings and feature reports so applications can decide whether to accept, reject, or review a conversion.
## Install
Install only the native packages and adapters an application needs. Unversioned `dotnet add package` commands select the current stable NuGet release.
```powershell
dotnet add package OfficeIMO.Word
dotnet add package OfficeIMO.Word.Pdf
dotnet add package OfficeIMO.Excel
dotnet add package OfficeIMO.Excel.Html
dotnet add package OfficeIMO.Excel.Pdf
dotnet add package OfficeIMO.Epub
dotnet add package OfficeIMO.Epub.Image
dotnet add package OfficeIMO.Adf
dotnet add package OfficeIMO.Confluence
dotnet add package OfficeIMO.Reader.Pdf
# Add every Reader adapter only when a broad ingestion host genuinely needs all formats.
dotnet add package OfficeIMO.Reader.All
dotnet add package OfficeIMO.OneNote
dotnet add package OfficeIMO.OneNote.Markdown
dotnet add package OfficeIMO.OneNote.Html
dotnet add package OfficeIMO.OneNote.Pdf
dotnet add package OfficeIMO.Reader.OneNote
```
Keep OfficeIMO package references in one application on the same published version.
Install the unified CLI with `dotnet tool install --global OfficeIMO.Tool`. See the [OfficeIMO.Tool guide](OfficeIMO.Tool/README.md) for global and repository-local installation, common commands, and contributor usage.
## Common workflows
### Create, reopen, and convert an offline OneNote section
```csharp
using OfficeIMO.OneNote;
using OfficeIMO.OneNote.Html;
using OfficeIMO.OneNote.Markdown;
using OfficeIMO.OneNote.Pdf;
var section = new OneNoteSection { Name = "Planning" };
var page = new OneNotePage { Title = "Release" };
var paragraph = new OneNoteParagraph();
paragraph.Runs.Add(new OneNoteTextRun { Text = "Validate the packed artifact" });
page.DirectContent.Add(paragraph);
section.Pages.Add(page);
section.Save("Planning.one");
OneNoteSection reopened = OneNoteSectionReader.Read("Planning.one");
File.WriteAllText("Planning.md", reopened.ToMarkdown());
reopened.SaveAsHtml("Planning.html");
reopened.SaveAsPdf("Planning.pdf");
reopened.SaveAsVisualHtml("Planning-visual.html");
reopened.SaveAsVisualPdf("Planning-visual.pdf");
reopened.Pages[0].ToImage().AtDpi(144).AsPng().Save("Planning-page-1.png");
```
### Create a Word document with page variants
```csharp
using OfficeIMO.Word;
using var document = WordDocument.Create("report.docx");
document.AddParagraph("Quarterly report").Style = WordParagraphStyles.Heading1;
document.AddParagraph("Created without Microsoft Office automation.");
document.HeaderDefaultOrCreate.AddParagraph("Internal");
document.HeaderFirstOrCreate.AddParagraph("Quarterly report");
document.FooterDefaultOrCreate.AddParagraph().AddPageNumber();
document.FooterEvenOrCreate.AddParagraph("Confidential — even page");
document.Save();
document.SaveAsPng("report-preview.png");
```
### Create an Excel report and export a range image
```csharp
using OfficeIMO.Excel;
using var workbook = ExcelDocument.Create("sales.xlsx");
var sheet = workbook.AddWorksheet("Sales");
sheet.CellValue(1, 1, "Product");
sheet.CellValue(1, 2, "Revenue");
sheet.CellValue(2, 1, "Alpha");
sheet.CellValue(2, 2, 120);
sheet.CellValue(3, 1, "Beta");
sheet.CellValue(3, 2, 92);
sheet.AddTable("A1:B3", hasHeader: true, name: "SalesTable", style: ExcelTableStyle.TableStyleMedium2);
sheet.AutoFitColumns();
workbook.Save();
sheet.Range("A1:B3").SaveAsSvg("sales-preview.svg");
```
### Export Word to PDF with conversion evidence
```csharp
using OfficeIMO.Word;
using OfficeIMO.Word.Pdf;
using var document = WordDocument.Load("proposal.docx");
var result = document.SaveAsPdf("proposal.pdf");
foreach (var warning in result.Warnings) {
Console.WriteLine(warning);
}
```
### Read, split, merge, and stamp PDFs
```csharp
using OfficeIMO.Pdf;
PdfDocument source = PdfDocument.Load("packet.pdf");
PdfDocumentReadResult firstPage = source.Read(new PdfReadOptions {
PageSelection = PdfPageSelection.Parse("1")
});
string firstPageText = string.Join('\n', firstPage.Pages[0].TextBlocks.Select(block => block.Text));
source.Pages.Extract("1-3").Save("packet-summary.pdf");
PdfDocument.Load("packet.pdf")
.MergeWith("appendix.pdf")
.Pages.Delete("2")
.Stamp.Text("Reviewed")
.Save("packet-final.pdf");
PdfAnalysisReport health = PdfDocument
.Load("packet-final.pdf")
.Analyze();
Console.WriteLine($"Readable: {health.CanRead}; rewrite safe: {health.CanRewrite}");
```
### Extract normalized content for indexing or RAG
```csharp
using OfficeIMO.Reader;
using OfficeIMO.Reader.Pdf;
using OfficeIMO.Reader.Zip;
OfficeDocumentReader reader = new OfficeDocumentReaderBuilder()
.AddPdfHandler()
.AddZipHandler()
.Build();
var chunks = reader.ReadFolder("KnowledgeBase",
new ReaderFolderOptions {
Recurse = true,
MaxFiles = 500,
DeterministicOrder = true
},
new ReaderOptions {
MaxChars = 8_000,
ComputeHashes = true
}).ToList();
```
## Document lifecycle
OfficeIMO uses one vocabulary across mutable document packages:
| Intent | API |
| --- | --- |
| Save to the associated destination | `Save()` / `SaveAsync()` |
| Save and associate a path | `Save(path)` / `SaveAsync(path)` |
| Write once to a caller-owned stream | `Save(stream)` / `SaveAsync(stream)` |
| Write a copy without changing the associated destination | `SaveCopy(path)` / `SaveCopyAsync(path)` |
| Produce bytes without changing document state | `ToBytes()` |
| Produce a new stream positioned at the beginning | `ToStream()` |
| Convert in memory | `To{Format}()` or `To{Format}Result()` |
| Write another format | `SaveAs{Format}()` / `SaveAs{Format}Async()` |
Saving to a caller-owned stream does not replace the document's associated path or source stream. A later parameterless `Save()` uses the existing association, or throws when the document has none. Caller-owned streams stay open. Seekable input streams are restored to their original position. Pure in-memory conversions remain synchronous; async APIs are used for real I/O and remote-resource resolution.
## Target frameworks and platform support
Most shipping libraries target `netstandard2.0`, `net8.0`, and `net10.0`. Many also include `net472` when built on Windows. `OfficeIMO.MarkdownRenderer.Wpf` adds Windows-specific targets, while the Markup CLI targets modern .NET. Check the package README or project file for the exact matrix.
- [x] No COM automation
- [x] No requirement for Microsoft Office, Excel, PowerPoint, Visio, or LibreOffice
- [x] Cross-platform native engines and converters except explicitly Windows-specific WPF hosting
- [x] Caller-controlled optional external tools for OCR and Mermaid rendering
