Extract Text From PowerPoint using C# .NET

Let’s explore the details on how we can efficiently extract the text from complete PowerPoint using C# .NET code snippet.

Now let’s develop our understanding about the above stated code snippet.

SlidesApi slidesApi = new SlidesApi(clientID, clientSecret);

Create an object of SlidesApi class where we pass the client credentials as arguments.

var textItems = slidesApi.GetPresentationTextItems(sourcePPTX, true, null);

Call the API to extract all textual content from PowerPoint presentation available in cloud storage.

StreamWriter sw = new StreamWriter("Test.txt");

Create StreamWriter which is going to help us in saving the extracted content on local drive.

foreach (var textItem in textItems.Items)

Iterate through each occurrence of extracted text and save the output in a textual file.

Extract Text From Particular Slide using cURL Commands

Another alternative to extract text from PowerPoint slides is by utilizing cURL commands. With cURL, you can interact with the Aspose.Slides Cloud API directly through HTTP requests, making it a flexible and accessible option for text extraction capabilities. So, by constructing the appropriate API endpoint and specifying the desired parameters, you can send a cURL command to retrieve text from specific slides or the entire presentation.

The first step in this approach is to generate a JWT access token. So, please execute the following command:

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=bb959721-5780-4be6-be35-ff5c3a6aa4a2&client_secret=4d84d5f6584160cbd91dba1fe145db14" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Now, execute the following command to extract text from the second slide of a PowerPoint presentation.

curl -v "https://api.aspose.cloud/v3.0/slides/{sourceFile}/slides/2/textItems?withEmpty=false" \
-X GET \
-H  "accept: application/json" \
-H  "authorization: Bearer {accessToken}" \
-o "Extracted.txt"

Replace sourceFile with the name of an input PowerPoint available in cloud storage, and accessToken with JWT access token generated above.


In conclusion, we have learned that the ability to extract text from PowerPoint slides is a valuable feature that allows us to access and utilize the textual content within presentations for various purposes. Whether it’s for data analysis, content parsing, or any other application, extracting text from PowerPoint slides empowers us to unlock the information contained within these files. By leveraging the Aspose.Slides Cloud SDK for .NET, we can easily and efficiently perform text extraction operations in .NET application or, the usage of cURL commands provides platform independent and a convenient approach.
