const pdf_file = 'Aspose.pdf';
AsposePdf().then(AsposePdfModule => {
    /*Extract text from a PDF-file*/
    const json = AsposePdfModule.AsposePdfExtractText(pdf_file);
    console.log("AsposePdfExtractText => %O", json.errorCode == 0 ? json.extractText : json.errorText);
});

ECMAScript/ES6:

import AsposePdf from 'asposepdfnodejs';
const AsposePdfModule = await AsposePdf();
const pdf_file = 'Aspose.pdf';
/*Extract text from a PDF-file*/
const json = AsposePdfModule.AsposePdfExtractText(pdf_file);
console.log("AsposePdfExtractText => %O", json.errorCode == 0 ? json.extractText : json.errorText);

Save PDF as Office Formats

One of the most popular features of Aspose.PDF for Node.js via C++ is to convert PDF documents to other formats without needing to understand the underlying structure of the resultant format.

Give the following snippet a try with your samples:

CommonJS:

const AsposePdf = require('asposepdfnodejs');
const pdf_file = 'Aspose.pdf';
AsposePdf().then(AsposePdfModule => {
    /*Convert a PDF-file to DocX and save the "ResultPDFtoDocX.docx"*/
    const json = AsposePdfModule.AsposePdfToDocX(pdf_file, "ResultPDFtoDocX.docx");
    console.log("AsposePdfToDocX => %O", json.errorCode == 0 ? json.fileNameResult : json.errorText);
});

ECMAScript/ES6:

import AsposePdf from 'asposepdfnodejs';
const AsposePdfModule = await AsposePdf();
const pdf_file = 'Aspose.pdf';
/*Convert a PDF-file to DocX and save the "ResultPDFtoDocX.docx"*/
const json = AsposePdfModule.AsposePdfToDocX(pdf_file, "ResultPDFtoDocX.docx");
console.log("AsposePdfToDocX => %O", json.errorCode == 0 ? json.fileNameResult : json.errorText);
