Find and Replace Text
Unlock the potential of your PDF editing capabilities with the remarkable feature of search and replace text. Whether you’re a business professional, a student, or an individual handling PDF documents, the ability to quickly find and replace specific text is invaluable. With the ever-growing need for efficient document processing, it’s essential to have powerful tools at your disposal. In this article, we will explore the process of searching and replacing text in PDF files using the Aspose.PDF Cloud SDK for Python.

No Adobe Acrobat or other software download and installation is required and perform all the PDF processing in the Cloud.

PDF Manipulation Cloud SDK

Aspose.PDF Cloud is a robust SDK providing a wide range of features to efficiently handle PDF files and streamline your document processing tasks. One of the standout capabilities of this SDK is the ability to search and replace text within PDF documents. Let’s dive in and harness the full potential of Aspose.PDF Cloud SDK for Python to revolutionize your PDF editing workflow.

So, the first step in using the API is the installation of Cloud SDK which is freely available for download over PIP and GitHub repository. Simply execute the following command on the terminal/command prompt to install the latest version of SDK on the system.

pip install asposepdfcloud

MS Visual Studio

When using Visual Studio, you may also add the reference in your Python project within the Visual Studio project. Please search asposepdfcloud as a package under the Python environment window. Please follow the steps numbered in the image below to complete the installation process.

Search and Replace Text using Python

Please follow the instructions given below to search a particular string and replace all its occurrences in the PDF document.

  • Firstly, create an instance of ApiClient class while providing Client ID Client Secret as arguments.
  • Secondly, create an instance of PdfApi class which takes ApiClient object as input argument.
  • Create variables specifying input PDF doucment.
  • Now create an object of TextReplaceListRequest defining text replace properties.
  • Finally, call the post_document_text_replace(..) method to intiate search and replace operation and save resultant in Cloud storage.

In the above code snippet, please specifically observe two parameters i.e. StartIndex and CountReplace. The StartIndex defines the specific occurrence of text from which text replace operation will be initiated and CountReplace defines the text occurrences that need to be replaced. In the image below, notice only two occurrences of the Product Family string are updated starting with index 2.

For your reference, the input URL2PDF.pdf and resultant Text-Replace-Output.pdf have been attached.

Search and Replace Text using cURL Command

In addition to using Aspose.PDF Cloud SDK for Python, you can also leverage the flexibility of cURL commands to perform text replacement in PDF documents. cURL is a command-line tool that allows you to make HTTP requests and interact with web services, making it a versatile option for integrating with the Aspose.PDF Cloud API. With cURL commands, you can easily send requests to the API endpoints and utilize the “Replace Text” feature to search for specific text patterns and replace them with new content.

Now, please execute the following command to generate the JWT token.

curl -v "" \
-d "grant_type=client_credentials&client_id=bbf94a2c-6d7e-4020-b4d2-b9809741374e&client_secret=1c9379bb7d701c26cc87e741a29987bb" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Now that we have generated our personalized JWT token, we need to execute the following cURL command to replace the Productivity string in the PDF document and save the updated document in the same cloud storage.

curl -X POST "" \
-H  "accept: application/json" \
-H  "authorization: Bearer <JWT Token>" \
-H  "Content-Type: application/json" \
-d "{  \"TextReplaces\": [    {      \"OldValue\": \"Product Family\",      \"NewValue\": \"Product Families\",      \"Regex\": true,      \"TextState\": {        \"FontSize\": 0,        \"Font\": \"Arial\",        \"ForegroundColor\": {          \"A\": 0,          \"R\": 252,          \"G\": 240,          \"B\": 3        },        \"BackgroundColor\": {          \"A\": 0,          \"R\": 252,          \"G\": 3,          \"B\": 248        },        \"FontStyle\": \"Regular\"      },      \"Rect\": {        \"LLX\": 0,        \"LLY\": 0,        \"URX\": 0,        \"URY\": 0      }    }  ],  \"DefaultFont\": \"Arial\",  \"StartIndex\": 2,  \"CountReplace\": 2}"


In conclusion, the ability to search and replace text in PDF documents is a valuable feature that can greatly enhance your document processing workflows. With the power of Aspose.PDF Cloud SDK for Python and the convenience of cURL commands, you have the necessary tools to seamlessly perform text replacement tasks in your PDF files.
