How to Extract Text from PowerPoint using Node.js

This section provides the details on how we can programmatically extract text from a PowerPoint presentation using the Node.js SDK.

Step 1: Initialize Configuration:

const { ParserApi, Configuration, ImagesRequest, FileInfo, ImagesOptions } = require("groupdocs-parser-cloud");

const config = new Configuration("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET");
const parserApi = new ParserApi(config);

Step 2: Setup File Info and Options: Initialize an object of the TextRequest class and pass the instance of the TextOptions class.

const fileInfo = new FileInfo();
// path to PowerPoint presentation
fileInfo.filePath = "input.pptx";

const options = new TextOptions();
options.fileInfo = fileInfo;

const request = new TextRequest(options);

Step 3: Extract Text from PowerPoint: Invoke the text method, and it will return the plain text from PowerPoint presentation.

parserApi.text(request).then(response => {
    console.log("Extracted text content:");
    console.log(response.text);
}).catch(err => {
    console.error("Error extracting text:", err);
});

Extract Text from PowerPoint via cURL

-d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET" \
-H "Content-Type: application/x-www-form-urlencoded"

Step 2 – Extract Text via API Call:

curl -v -X POST "https://api.groupdocs.cloud/v1.0/parser/text" \
-H  "accept: application/json" \
-H  "authorization: Bearer {ACCESS_TOKEN}" \
-H  "Content-Type: application/json" \
-d 
    "{  
        \"FileInfo\": 
        {
            \"FilePath\": \"input.pptx\",
            \"StorageName\": \"internal\"
