You’ll create a React project with Vite, add the Nutrient dependency, and implement a component to display PPT/PPTX files. The solution offers additional capabilities like text editing, annotations, and signatures without requiring MS Office software or licenses. In this blog post, learn how to build a [React PowerPoint viewer](https://www.nutrient.io/guides/web/viewer/office-documents.md) using Nutrient Web SDK. You’ll open and view PPT or PPTX files directly in your web browser using client-side processing (no server required). The image below shows what you’ll be building.![A PPTX presentation rendered in the browser by a React PowerPoint viewer built with Nutrient Web SDK](@/assets/images/blog/2023/how-to-build-a-powerpoint-viewer-using-javascript/result.png) You can check out the [demo](https://www.nutrient.io/demo/office-viewer) to see it in action. ## Opening and rendering Office documents in the browser Nutrient Web SDK brings support for Word, Excel, and PowerPoint formats to your application, without you or your users needing any MS Office software, MS Office licenses, or third-party open source software. The technology works by converting an Office document to PDF directly in the browser, and the document is then rendered in our JavaScript viewer. ## Unlocking more capabilities with Office-to-PDF conversion By converting an Office document to PDF using client-side JavaScript, you have the option to support a rich array of additional Office document functionality, such as: - **Text editing** — Edit text directly in the displayed Office document. - **Page manipulation** — Organize documents by adding, removing, or rearranging pages. - **Annotations** — Boost collaboration by adding text highlights, comments, or stamps. - **Adding signatures** — Draw, type, or upload a signature directly to an Office document. [Explore Demo](https://www.nutrient.io/demo/office-viewer) ## Requirements to get started To get started, you’ll need: - The [latest version of Node.js](https://nodejs.org/en/). - A package manager compatible with npm. This guide contains usage examples for [Yarn](https://yarnpkg.com/) and the [npm](https://docs.npmjs.com/cli/v7/commands/npm) client (installed with Node.js by default). ## Setting up a new React project with Vite 1. To get started, create a new React project using Vite: ```bash # Using Yarn yarn create vite nutrient-react-example --template react # Using npm npm create vite@latest nutrient-react-example -- --template react ``` 2. Change to the created project directory: ``` cd nutrient-react-example ``` ## Adding Nutrient to your project 1. Add the Nutrient dependency: ```bash npm install @nutrient-sdk/viewer # or yarn add @nutrient-sdk/viewer # or pnpm install @nutrient-sdk/viewer ``` 2. The Nutrient Web SDK loads its WebAssembly and supporting files from a local path, so you need to copy them to the public folder. Start by installing the required copy plugin: ```bash npm install -D rollup-plugin-copy ``` Then, update your Vite configuration (`vite.config.ts`) to copy the SDK’s asset files during build: ```ts import { defineConfig } from 'vite'; import react from '@vitejs/plugin-react'; import copy from 'rollup-plugin-copy'; export default defineConfig({ plugins: [ copy({ targets: [ { src: 'node_modules/@nutrient-sdk/viewer/dist/nutrient-viewer-lib', dest: 'public/', }, ], hook: 'buildStart', }), react(), ], }); ``` ## Displaying a PowerPoint document 1. Add a PowerPoint (PPT, PPTX) document you want to display to the public directory. You can use our [demo document](https://www.nutrient.io/downloads/slides.pptx) as an example. 2. Now that everything is set up, you’ll render a PDF using the Nutrient SDK. Basic usage in `App.tsx`: ```tsx import { useEffect, useRef } from 'react'; function App() { const containerRef = useRef(null); useEffect(() => { const container = containerRef.current; let cleanup = () => {}; (async () => { const NutrientViewer = (await import('@nutrient-sdk/viewer')).default; // Unload any previous instance. NutrientViewer.unload(container); if (container && NutrientViewer) { NutrientViewer.load({ container, document: 'slides.pptx', // Path to your PowerPoint document. baseUrl: `${window.location.protocol}//${ window.location.host }/${import.meta.env.PUBLIC_URL?? ''}`, }); } cleanup = () => { NutrientViewer.unload(container); }; })(); return cleanup; }, []); return (
); } export default App; ``` 3. Start the app and run it in your default browser: ```bash # Using Yarn yarn dev # Using npm npm run dev ``` ## A note about fonts In client-side web applications for Microsoft Office-to-PDF conversion, Nutrient addresses font licensing constraints through font substitutions, typically replacing unavailable fonts with their equivalents — like Arial with Noto. For precise font matching, you can provide your own fonts, embed them into source files, or designate paths to your `.ttf` fonts for custom solutions. ## Adding even more capabilities Once you’ve deployed your viewer, you can start customizing it to meet your specific requirements or easily add more capabilities.

Yes. Nutrient Web SDK renders both the legacy PPT format and modern PPTX by converting the file to PDF in the browser, so the same component handles either format. #### Does the React PowerPoint viewer need Microsoft Office or a server? No. Conversion and rendering run entirely client-side via WebAssembly — there’s no Microsoft Office installation, no MS Office licenses, and no server-side processing required. #### What can I do beyond viewing the presentation? Because the document is converted to PDF, you can also edit text, add or rearrange pages, annotate, redact, and add eSignatures on the rendered file using the same SDK. --- ## Related pages - [The business case for accessibility: Five ways it drives enterprise value](/blog/5-ways-accessibility-drives-enterprise-value.md) - [Accessibility Untangled Why It Matters Guide](/blog/accessibility-untangled-why-it-matters-guide.md) - [Advanced Techniques For React Native Ui Components](/blog/advanced-techniques-for-react-native-ui-components.md) - [`vector_store` holds your indexed documents (see the multimodal RAG post](/blog/agentic-rag.md) - [Ai Document Automation Extraction To Action](/blog/ai-document-automation-extraction-to-action.md) - [Ai Legal Assistant Document Authoring](/blog/ai-legal-assistant-document-authoring.md) - [Angular File Viewer Pdf Image Office Files](/blog/angular-file-viewer-pdf-image-office-files.md) - [Auto Tagging And Document Accessibility In Dotnet Sdk](/blog/auto-tagging-and-document-accessibility-in-dotnet-sdk.md) - [Best Document Ai Platforms](/blog/best-document-ai-platforms.md) - [Best Document Viewers](/blog/best-document-viewers.md) - [The CEO’s AI playbook: Why decision architecture beats model selection](/blog/ceo-ai-playbook-decision-architecture.md) - [1.
