Need documentation for integrating asopse xlsx ppts docx viewer in react application

Aspose.Total Product Family

I know Aspose provides APIs for document rendering and viewing, but I’m having trouble finding clear documentation or examples for integrating these viewers into a React front-end.

My main requirements are:

  1. View documents directly in the browser (no downloads)
  2. Support for Excel, PowerPoint, and Word files
  3. Preferably integrate as React components or through an iframe/web viewer

If anyone has experience with:

  • Using Aspose.Cells, Aspose.Slides, or Aspose.Words in a React or web environment, or
  • Setting up a backend (Java) to serve files for Aspose viewing

Please share documentation links, working examples, or best practices.

Thanks in advance for any help or pointers!

Summary
You can display Word, Excel, and PowerPoint files in a React app without forcing a download by converting the documents on a server to a web‑friendly format (HTML, PDF, or images) using Aspose libraries (on‑premise SDKs or Aspose Cloud) and then embedding the result in the React UI (e.g., via an <iframe> or a custom component).

Why it works

  • On‑premise SDKs (Aspose.Words, Aspose.Cells, Aspose.Slides) provide Save/Export methods that can render a document to HTML, PDF, PNG, etc. They do not ship a ready‑made React component, so you need a small back‑end service that performs the conversion.
  • Aspose Cloud offers REST endpoints (/words/convert, /cells/convert, /slides/convert) that return the same formats directly, which is convenient for a lightweight Node.js back‑end.
  • Modern browsers can display HTML, PDF and images natively, so once the server returns one of those formats the front‑end only needs to embed it.

What to do next

  1. Choose a back‑end approach
  • If you already have a .NET service, use the on‑premise SDKs.
  • If you prefer a minimal Node.js service or want to avoid installing the full libraries, use Aspose Cloud (requires a Cloud subscription).

  1. Add the appropriate Aspose package
    | Platform | Library | Package manager |
    |----------|---------|-----------------|
    | .NET (Core/5/6+) | Aspose.Words, Aspose.Cells, Aspose.Slides | dotnet add package Aspose.Words (and the others) |
    | Java | aspose-words, aspose-cells, aspose-slides | Maven com.aspose:aspose-words … |
    | Node.js (Cloud) | asposewordscloud, asposecellscloud, asposeslidescloud | npm i asposewordscloud … |

  2. Create a simple conversion endpoint (example shown for .NET 6 Web API and Node.js with Aspose Cloud – you will need to adapt paths, licensing, and error handling to your environment).

  3. Build a React component that consumes the endpoint

src/components/DocumentViewer.tsx
import React from 'react';

interface Props {
type: 'word' | 'excel' | 'ppt';
fileName: string; e.g. "sample.docx"
}

const DocumentViewer: React.FC<Props> = ({ type, fileName }) => {
const src = `/api/view/${type}/${encodeURIComponent(fileName)}`;
return (
<iframe
src={src}
title="Document viewer"
style={{ width: '100%', height: '80vh', border: 'none' }}
/>
);
};

export default DocumentViewer;

  1. Optional – return images for faster loading (one PNG per slide/page/worksheet) and render them in a carousel or grid.

  2. Configure licensing / credentials

  • On‑premise SDKs – place the .lic file in the server project and load it at startup.
  • Cloud – store the Client ID and Secret securely (environment variables, secret manager) and use them when constructing the API objects.
  1. Validate the flow
  2. Run the back‑end locally.
  3. Put a few .docx, .xlsx, .pptx files in the server’s folder (or upload them to Cloud storage).
  4. Start the React app and navigate to a page that uses <DocumentViewer …/>.
  5. Verify the document appears inside the iframe without prompting a download.

Next‑steps checklist

  1. Decide between on‑premise SDKs and Aspose Cloud.
  2. Add the required NuGet / npm / Maven packages.
  3. Implement an HTTP endpoint that loads the file and calls Save(..., SaveFormat.Html) (or PNG/PDF as preferred).
  4. Expose the endpoint URL to the React front‑end.
  5. Use the provided <DocumentViewer> component (or a similar wrapper) to embed the result.
  6. Test with sample files and adjust MIME types or caching headers if needed.
  7. Deploy both services, ensuring the Aspose license file or Cloud credentials are correctly configured.

Caveat
The evidence retrieved for this request does not contain specific documentation links or code samples for Aspose viewer integration in React. The guidance above is based on general knowledge of Aspose SDKs and typical patterns for server‑side conversion and client‑side embedding. Please refer to the official Aspose documentation for the exact API signatures, licensing details, and latest best‑practice recommendations:

  • Aspose.Words for .NET –
  • Aspose.Cells for .NET –
  • Aspose.Slides for .NET –
  • Aspose Cloud REST API –

If you encounter a specific error or need a concrete example for a particular back‑end language, feel free to ask for a more targeted snippet.

:warning: I could not fully verify this explanation against the retrieved sources. Please double-check the behaviour in your environment and confirm the exact SDK/version.

I have aspose total license, will be using aspose java suit for this, can you provide points for java and will excel will be as same as uploaded xlsx ?

@trivedi365,

Aspose (on-premise) Java package provides libraries for document processing, but they do not include a pre-built, ready-to-use React viewer component. The core Aspose Java APIs are server-side libraries used for document manipulation, rendering, and conversion.
To view documents in a React front-end, the general approach could be use Aspose APIs to implement a server-side process (backend) to convert the document pages into a web-viewable format (like HTML, images, or PDF) and then display that output in your React application by yourselves.

Your Java backend can use the relevant Aspose APIs (Aspose.Words, Aspose.Cells, Aspose.Slides) to process the documents.
Recommended Approach: Convert to HTML or Images.
Convert to HTML: Convert the document to HTML (or HtmlFixed) format. This can provide a good representation of the document structure and allows for text search.
i) Aspose.Words: Use Document.save() with SaveFormat.Html or SaveFormat.HtmlFixed.
ii) Aspose.Cells: Convert Excel files to HTML using Workbook.save() with SaveFormat.Html.
iii) Aspose.Slides: Convert presentation to HTML using Presentation.save() with SaveFormat.Html.

Convert to Images: Convert each page of the document into an image (JPEG, PNG). This is simple to implement and ensures accurate rendering across all browsers. The downside is that text is not searchable and file sizes might be larger.

Alternatively, you may go for Aspose for Cloud APIs for the purpose.

while conversion to html will not retain the exact format of the content, I want What you get what you see kind of feature, where there is no alteration of original document content formatting

@trivedi365,

You may try to render pages/ranges to images via the Aspose (Java) APIs and then use those images to display in your React app.
