Embed Native Word Editing and Review in Your Web App
Apryse DOCX Editor is a client-side JavaScript SDK that lets users create, edit, and review Word DOCX files directly in the browser. It edits each file’s native OOXML with no upload or server round-trip. The same API lets automation pipelines act on tracked changes and content without any UI interaction.
The User Experience
Edit DOCX in the Browser, Not a Converted Copy
Format text, tables, headers, footers, and images directly in the DOCX file. What your users don’t touch stays exactly as it was when the file reopens in Word.
Track Changes and Comments, Built In
Navigate, accept, reject, and comment on tracked changes directly in the editor UI. Redlines hold up when the file reopens in Word, not flattened into plain text.
A Familiar, Word-Style Editing Experience
Fonts, styles, lists, and page layout behave the way users already expect from Word, with a WYSIWYG (What You See is What You Get) experience so there’s no new editor to learn.
Accessible by Default
The UI meets WCAG 2.2 Level AA, so accessibility is built in rather than bolted on. See the accessibility guide.
Three Modes: Viewing, Editing, and Reviewing
Viewing Mode
In Viewing mode, the document cannot be edited. Users have read-only access to navigate, search, and read the file without making changes.
Editing Mode
Full editing capabilities are enabled: text and style editing, tables, headers, footers, images, and comments, all driven from your code or the built-in UI.
Framework Support: React, Angular, Vue, Next.js, and More
DOCX Editor works with React, Angular, Vue, NuxtJS and Next.js, and inside platforms like Salesforce, Appian, Mendix, and OutSystems. It mounts to a DOM element, so the integration is the same in each. Viewing, PDF editing, and spreadsheet editing share the same API and UI framework, so what you use here carries across the rest of the Web SDK.
Get DOCX Editor Running
Enabling the editor is a constructor option. Pass initialMode: ‘docxEditor’ to open straight into DOCX editing, or enableOfficeEditing: true when the same viewer handles other file types too. Anything that touches the document waits for the documentLoaded event.

DOCX Editor SDK Features at a Glance
What the DOCX Editor add-on does, and what you can drive from code.
Deployment and Integration
DOCX Editor runs in the browser as part of the Apryse Web SDK.
How Native DOCX Editing Works
Editing runs in the browser on a WebAssembly build of Apryse’s C++ engine, so nothing uploads and no server sits in the edit path. The editor works on the file's native OOXML rather than converting to JSON or HTML and back, so tables, headers, footers, and tracked changes stay intact.
File Support
Create new DOCX files from blank, or open and edit existing ones. Save back to DOCX or PDF.
Customization
Once the editor signals ready, you drive everything through the JavaScript API: accepting or rejecting tracked changes, programmatic text edits, search and replace, and export.
Client-Side Processing
DOCX Editor works on the file’s native OOXML rather than converting to JSON or HTML and back. The file is read into browser memory and processed there. DOCX Editor makes no network call to Apryse.
Word-Correct Tracked Changes
Tracked changes are written as native OOXML markup that a reviewer’s own copy of Word already reads, not a plain-text diff layered on top after the fact.
When to Consider DOCX Editor
Word-Fidelity Workflow
You want redlines, styles, and structure to stay intact through rendering, editing, and exporting, with no round-trip losses.
Data Security
When your users need to open and edit Word documents inside your app, with no data leaving the browser.
DOCX Editor Alternatives: How Four Approaches Compare
Adding Word workflows to a web app usually comes down to four options: a self-hosted office service, a rich text editor, a full-platform document SDK, or building the surface yourself. Here’s how a client-side editor compares.
Over a self-hosted office suite
Office suites need a document server for every open, save, and conversion that’s hosted, scaled, and patched by you. DOCX Editor edits Word files in the browser, in memory, with no editing server.
Over a rich text editor
Rich text editors convert DOCX into JSON and rebuild the file on export, so custom styles, content controls, and document metadata can drop, and export writes a single section only. DOCX Editor edits the OOXML directly, and tracked changes are included rather than priced as a separate add-on.
For a detailed comparison, see DOCX Editor vs. Tiptap or the native OOXML vs. JSON architecture guide.
Over a full platform document SDK
Full-platform SDKs often bolt Office editing onto a server or a proprietary JSON format, with PDF, DOCX, and spreadsheet handled as separate products on separate engines. DOCX Editor, Spreadsheet Editor, and PDF Editing share one WebAssembly core and one API. What you build for one carries to the others.
Over building it yourself
The OOXML spec is large and Microsoft revises it yearly, so hand-built editors tend to pass early tests and then break on documents later on. Buying the editor turns that into a component maintained against the spec for you.
The fastest way to compare any of these on your own content: round-trip a real file through each editor and reopen it in Word.
Where Developers Use a DOCX Editor SDK
In-app document review
Open a file in View mode so reviewers read it inside your app, under your own permissions. No export to Word or a PDF reader first.
Redline review and approval
A reviewer accepts, rejects, or comments on tracked changes in your app. No emailing versions back and forth.
Automated tracked-change triage
Code auto-accepts routine tracked changes through TrackedChangeManager and routes only the substantive ones to a reviewer.
