## About

InjOffice is a set of browser and server libraries for editing office artifacts. It adds plain-JSON models, pure transformation engines, provider-neutral agent change sets, optional editor integrations, and surgical OOXML patching. A hosted InjOffice service is not required: consumers can use the browser-local WASM engine, run offline, inject their own backend, or opt into the in-repo injoffice-server .

The repository is a monorepo with independently consumable TypeScript packages, private apps, and Go modules. The TypeScript packages target Node.js 22 or newer and modern bundlers. UI integrations use React and, where noted, Univer OSS as an optional editor shell. Univer is not the file authority. Native paint compilers are a preview mode.

The original OOXML bytes remain the authority. The supported path is XLSX-first and the same shape for documents and presentations:

Go Extract* reads package bytes ( xlsxpatch.ExtractNativeWorkbookV1 / ExtractNativeWorkbookV2 , docxpatch.ExtractNativeDocumentV1 , pptxpatch.ExtractNativePPTX ).

The result is versioned native JSON consumed by @injoffice/sheets , @injoffice/docs , and @injoffice/pptx-native .

TypeScript paint compilers emit renderer-neutral preview commands. Paint is not a save path.

Go Apply* writes those mutations back into the original archive.
