        const rawModule = spireModule.default || spireModule;
        window.wasmModule = typeof rawModule === 'function'
          ? await rawModule({ locateFile: p => p.endsWith('.wasm') ? `${publicUrl}/${p}` : p })
          : rawModule;
        setWasmModule(window.wasmModule);
      } catch (error) {
        console.error('Failed to load spire.xls.js WASM module:', error);
      }
    })();
  }, []);

  // Function to convert an Excel Worksheet to an Image
  const ExcelToImage = async () => {

General Steps to Convert Word to PDF in React

Converting Word documents to PDF in React using Spire.Doc for JavaScript involves several key steps. Here's a step-by-step guide to help you get started:

Load Fonts: Load necessary font files into the virtual file system (VFS) for accurate rendering.
Prepare Document: Fetch the input Word file, create a new document, and load the file into it.
Set PDF Conversion Parameters: Configure any necessary conversion options, such as embedding fonts or preserving bookmarks.
Convert to PDF: Convert the document to PDF with the specified options.
Download PDF: Read the generated PDF from the VFS, create a Blob object, and trigger the download for the user.

Convert Word to PDF with Installed Fonts Embedded

When converting documents, you may want to ensure that all fonts used in the Word document are embedded into the PDF. This is especially important for maintaining the document's layout.

Spire.Doc for JavaScript offer the ToPdfParameterList class to customize the conversion options. The key parameter set here is IsEmbeddedAllFonts, which guarantees that all fonts are included in the final PDF.

The following code snippet demonstrates how to embed installed fonts when converting Word to PDF using JavaScript.

JavaScript

Copy

import React, { useState, useEffect } from 'react';

function App() {
  const [wasmModule, setWasmModule] = useState(null);
  // Load Spire.Doc
  useEffect(() => {
    (async () => {
      try {
        const publicUrl = process.env.PUBLIC_URL || '';
        const spireModule = await import(/* webpackIgnore: true */ `${publicUrl}/spire.doc.js`);
        const rawModule = spireModule.default || spireModule;
        window.wasmModule = typeof rawModule === 'function'
          ? await rawModule({ locateFile: p => p.endsWith('.wasm') ? `${publicUrl}/${p}` : p })
          : rawModule;
        setWasmModule(window.wasmModule);
      } catch (error) {
        console.error('Failed to load spire.doc.js WASM module:', error);
      }
    })();
  }, []);

  // Function to convert Word to PDF
  const convertWordToPdf = async () => {
    const wasmModule = window.wasmModule.spiredoc;
    if (wasmModule) {
      // Load the font files into the virtual file system (VFS)
      await window.spire.FetchFileToVFS('times.ttf', '/Library/Fonts/', `${process.env.PUBLIC_URL}/static/font/`);
      await window.spire.FetchFileToVFS('timesbd.ttf', '/Library/Fonts/', `${process.env.PUBLIC_URL}/static/font/`);
      await window.spire.FetchFileToVFS('timesbi.ttf', '/Library/Fonts/', `${process.env.PUBLIC_URL}/static/font/`);
      await window.spire.FetchFileToVFS('timesi.ttf', '/Library/Fonts/', `${process.env.PUBLIC_URL}/static/font/`);

      // Fetch the input file and add it to the VFS
      const inputFileName = 'input.docx';
      await window.spire.FetchFileToVFS(inputFileName, '', `${process.env.PUBLIC_URL}/static/data/`);

      // Create a new document
      const doc = new wasmModule.Document();

      // Load the word file
      doc.LoadFromFile(inputFileName);

      // Create a parameter list for the PDF conversion
      let parameters = new wasmModule.ToPdfParameterList();

      // Set the parameter to embed all fonts in the PDF
      parameters.IsEmbeddedAllFonts = true;

      // Specify the input and output file paths
      const outputFileName = 'ToPDF.pdf';

      // Save the document as a PDF file
      doc.SaveToFile({ fileName: outputFileName, paramList: parameters });

      const modifiedFileArray = window.dotnetRuntime.Module.FS.readFile(outputFileName);
      const modifiedFile = new Blob([modifiedFileArray], { type: 'application/pdf' });

      // Create download link
      const url = URL.createObjectURL(modifiedFile);
      const a = document.createElement('a');
      a.href = url;
      a.download = outputFileName;
      document.body.appendChild(a);
      a.click();
      document.body.removeChild(a);
      URL.revokeObjectURL(url);

      // dispose 
      doc.Dispose();

    }

  };

  return (
    <div style={{ textAlign: 'center', height: '300px' }}>
      <h1>Convert Word to PDF Using JavaScript in React</h1>
      <button onClick={convertWordToPdf} disabled={!wasmModule}>
        Generate
      </button>
    </div>
  );
}

export default App;

Convert Word to PDF with Non-Installed Fonts Embedded

For fonts that are not installed on your machine but applied in the Word document, you can also embed these fonts directly into the PDF. This ensures that the document looks consistent across different devices.

To embed non-installed fonts, start by creating a ToPdfParameterList object to customize the conversion process. Next, define a list of custom fonts for the PDF output. Finally, assign the custom font paths to the parameters using the ToPdfParameterList.PrivateFontPaths property.

The following code snippet demonstrates how to embed non-installed fonts when converting Word to PDF using JavaScript.

JavaScript

Copy

import React, { useState, useEffect } from 'react';

function App() {
  const [wasmModule, setWasmModule] = useState(null);
  // Load Spire.Doc
  useEffect(() => {
    (async () => {
      try {
        const publicUrl = process.env.PUBLIC_URL || '';
        const spireModule = await import(/* webpackIgnore: true */ `${publicUrl}/spire.doc.js`);
        const rawModule = spireModule.default || spireModule;
        window.wasmModule = typeof rawModule === 'function'
          ? await rawModule({ locateFile: p => p.endsWith('.wasm') ? `${publicUrl}/${p}` : p })
          : rawModule;
        setWasmModule(window.wasmModule);
      } catch (error) {
        console.error('Failed to load spire.doc.js WASM module:', error);
      }
    })();
  }, []);

  // Function to convert Word to PDF
  const convertWordToPdf = async () => {
    const wasmModule = window.wasmModule.spiredoc;
    if (wasmModule) {
      // Load the font files into the virtual file system (VFS)
      await window.spire.FetchFileToVFS('FreebrushScriptPLng.ttf', '/Library/Fonts/', `${process.env.PUBLIC_URL}/static/font/`);

      // Fetch the input file and add it to the VFS
      const inputFileName = 'input.docx';
      await window.spire.FetchFileToVFS(inputFileName, '', `${process.env.PUBLIC_URL}/static/data/`);

      // Create a new document
      const doc = new wasmModule.Document();

      // Load the word file
      doc.LoadFromFile(inputFileName);

      // Create a parameter list for the PDF conversion
      let parameters = new wasmModule.ToPdfParameterList();

      // Define a list of custom fonts to be used in the PDF
      let fonts = new wasmModule.PrivateFontPath('Freebrush Script', 'FreebrushScriptPLng.ttf');

      // Assign the custom font paths to the parameters for the PDF conversion
      parameters.PrivateFontPaths = fonts;

      // Save the document as a PDF file
      const outputFileName = 'ToPDF.pdf';
      doc.SaveToFile({ fileName: outputFileName, paramList: parameters });

      const modifiedFileArray = window.dotnetRuntime.Module.FS.readFile(outputFileName);
