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). ## Sponsors  <p> <a href="https://github.com/KelvinTegelaar" title="KelvinTegelaar"><img src="https://avatars.githubusercontent.com/u/49186168?u=49610dcd84d6c868d9e47c1a64ac137f3da24808&v=4" width="48" height="48" alt="KelvinTegelaar" /></a> <a href="https://github.com/apbirch67" title="Andrew Birch"><img src="https://avatars.githubusercontent.com/u/12010032?u=79082c6c1f026e3ab39dae7a4aff8e8fadeeeeea&v=4" width="48" height="48" alt="Andrew Birch" /></a> <a href="https://github.com/thomas-moeller" title="Thomas Møller"><img src="https://avatars.githubusercontent.com/u/37923349?u=e5b9b9d52dc33256937ace98623e3b7c6aead98a&v=4" width="48" height="48" alt="Thomas Møller" /></a> <a href="https://github.com/jakehildreth" title="Jake Hildreth"><img src="https://avatars.githubusercontent.com/u/93942157?u=e1e8d3f460d775c44f5491711ad1c47a5005fb5c&v=4" width="48" height="48" alt="Jake Hildreth" /></a> <a href="https://github.com/complea" title="Complea"><img src="https://avatars.githubusercontent.com/u/144781871?v=4" width="48" height="48" alt="Complea" /></a> <a href="https://github.com/DarthPanda12" title="DarthPanda12"><img src="https://avatars.githubusercontent.com/u/294241377?v=4" width="48" height="48" alt="DarthPanda12" /></a> </p> [See all sponsors](SPONSORS.md)  ## 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 | | --- | --- | --- | | Drawing, OneNote, Markdown, RTF, OpenDocument, AsciiDoc, LaTeX, OPML, DocBook, CSV, EPUB, ZIP | No third-party document engine | Parsing, object models, writing, rendering primitives, safety limits, and diagnostics | | CAB and passive MSI extraction | None | Managed Cabinet decoding, embedded MSI payload mapping, bounded extraction, and path validation | | JavaScript and browser assets | None | Strict TypeScript document layers, streaming XLSX/CSV and embedded portable scripts | | Apple iWork source reading | No third-party document engine | Bounded package, Snappy/IWA, protobuf-envelope, record-preservation, and Pages/Numbers/Keynote projection layers | | Word, Excel, PowerPoint | [Open XML SDK](https://github.com/dotnet/Open-XML-SDK) | Fluent/editable object models, lifecycle, validation, conversions, managed image export, and first-party `.doc`/`.xls`/`.ppt` support | | HTML document contracts (`OfficeIMO.Html.Core`) | None | Owned nodes, immutable snapshots, edits and parser/charset contracts | | HTML syntax provider (`OfficeIMO.Html.AngleSharp`) | AngleSharp and `System.Text.Encoding.CodePages` | Translation to owned nodes, selector/serialization services and charset-provider integration | | HTML conversion and rendering | [AngleSharp](https://github.com/AngleSharp/AngleSharp) and AngleSharp.Css | Resource policy, media filtering, layout scene, and PNG/JPEG/TIFF/SVG/WebP output; opt-in bridges add RTF, MHTML, email-image, and PDF workflows | | PDF | No third-party PDF or cryptographic dependency | PDF parsing/writing/rendering, password security, signature structure, preservation policy, limits, and diagnostics | | Email, email stores, and address books | `System.Text.Encoding.CodePages` | EML/MIME, MSG/OFT, TNEF, mbox, PST/OST, OLM, EMLX, Outlook OAB, MAPI projection, protected-wrapper preservation, limits, and diagnostics | | Optional Security provider | [Bouncy Castle](https://www.bouncycastle.org/csharp/) and `System.Security.Cryptography.Xml` | CMS/S/MIME/RFC 3161/X.509/XML DSig orchestration behind one typed provider explicitly supplied to Word, PDF, or Email | | Optional ChartForgeX bridge | [ChartForgeX](https://github.com/EvotecIT/ChartForgeX) | Vector-first visual artifact conversion, OfficeDrawing fidelity reports, and Word, Excel, PowerPoint, and PDF placement | | Visio | `System.IO.Packaging` | VSDX/VSTX/VSSX and macro-enabled package model, bounded legacy binary import, diagram builders, editing, validation, topology, and PNG/JPEG/TIFF/SVG/WebP export | | Reader.Yaml | [YamlDotNet](https://github.com/aaubry/YamlDotNet) | Reader projection, chunking, limits, locations, and diagnostics | | MarkdownRenderer.Wpf | Microsoft WebView2 | Rendering shell, presets, plug-in model, and WPF host contract | | Optional document AI | [OfficeIMO.AI](OfficeIMO.AI/README.md) and [IntelligenceX adapter](OfficeIMO.AI.IntelligenceX/README.md) | Read-only questions, summaries, field extraction and proposed structure with bounded source evidence; .NET 10 and caller-selected model execution | | Optional OCR providers | A caller-supplied executable or an installed Tesseract CLI | Neutral request/result/geometry contracts, bounded provider execution, and opt-in Reader/PDF integrations | | Google Workspace packages | `System.Text.Json` and platform HTTP/cryptography | Credentials abstraction, request/retry logic, Drive placement, translation plans, and reports; no Google client SDK | | Converter packages not listed above | Only the OfficeIMO format packages they connect | Feature mapping, limits, loss reports, and destination APIs | ## At a glance | Surface | Current repository coverage | | --- | ---: | | Modern Office authoring/editing | `.docx`, `.xlsx`, `.pptx`, `.vsdx`, `.vstx`, `.vssx`, `.vsdm`, `.vstm`, `.vssm` | | First-party legacy binary support | Word 97–2003 `.doc`, Excel BIFF8 `.xls`, PowerPoint 97–2003 `.ppt`/`.pot`/`.pps` | | First-party Apple iWork support | Modern IWA-based `.pages`, `.numbers`, and `.key` read/inspect plus editable or visual-fallback projection; bounded template-free Keynote text/image/table slides, Pages body documents and Numbers scalar-table spreadsheets | | First-party offline OneNote support | Desktop/FSSHTTP `.one`, `.onetoc2`, `.onepkg` | | Managed PNG/JPEG/TIFF/WebP/SVG document export | Drawing; Word, Excel, PowerPoint, HTML, OneNote, Visio, and PDF; HTML-backed email and EPUB; ODT/ODS/ODP through their Office adapters | 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> <img src="Website/static/images/studio/workspace-light.png" width="62%" alt="OfficeIMO Studio on the desktop with a sample PDF, page navigation and document tools." /> <img src="Docs/Images/StudioApple/ipad-read.jpg" width="30%" alt="OfficeIMO Studio on iPad reading a PDF with the page list." /> </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. ## Packages and tools Every checked item below is implemented today.

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. ```mermaid flowchart LR Word["Word: DOC/DOCX"] <--> HTML["HTML"] Word <--> Markdown["Markdown"] Word <--> RTF["RTF"] Word <--> ODT["OpenDocument: ODT"] Word -->|"layout export"| PDF["PDF"] PDF -->|"semantic recovery"| Word Excel["Excel: XLS/XLSX"] <--> HTML Excel <--> ODS["OpenDocument: ODS"] Excel -->|"layout export"| PDF PDF -->|"logical tables only"| Excel PowerPoint["PowerPoint: PPT/POT/PPS/PPTX"] <--> HTML PowerPoint <--> ODP["OpenDocument: ODP"] PowerPoint -->|"layout export"| PDF PDF -->|"editable objects, visual pages, hybrid, or tables"| PowerPoint OneNote["OneNote: ONE/ONETOC2/ONEPKG"] -->|"semantic adapter"| Markdown OneNote -->|"semantic adapter"| HTML OneNote -->|"semantic or visual adapter"| PDF OneNote -->|"visual projection"| DrawingCanvas["Drawing canvas"] EPUB["EPUB"] -->|"retained chapter HTML/resources"| HTML DrawingCanvas --> Images["PNG/JPEG/TIFF/SVG/WebP"] DrawingCanvas --> HTML DrawingCanvas --> PDF Markdown <--> HTML Markdown <--> RTF Markdown <--> AsciiDoc["AsciiDoc"] Markdown <--> Latex["LaTeX"] Markdown --> PDF AsciiDoc -->|"direct PDF adapter"| PDF Latex -->|"direct PDF adapter"| PDF HTML <--> RTF HTML --> PDF RTF -->|"layout export"| PDF PDF -->|"semantic recovery"| RTF ``` 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.
