                Step 1: Install the Request Module

                Let’s start by installing the request module to manage new packages written in Python. In your command line, type python -m pip install request and click the Enter button to install the request module.

                Step 2: Open Visual Studio Code Editor

                After installing the requests module, open the Visual Studio Code editor. You can also use your favorite editor in Python.

                Next, input the Python sample code inside the editor. You can get the source code here.

                Step 3: Add API Key

                In line 6, add your API Key. You can obtain the API Key from your PDF.co dashboard.

                If you do not have a PDF.co account yet, please sign up here to obtain the API Key.

                Add API Key

                Step 4: Source and Output Name

                In line 12, specify the name of your source PDF file.

                In line 15, provide the name for your desired JSON output file.

                Source and Output Name

                Step 5: Add Template Name

                In line 20, specify the template name that contains the parsed data of the mathematical expressions extracted from the PDF document. You can create a new template using the PDF.co Document Parser Template Editor. For a quick guide on creating a template, you can refer to this tutorial.

                Add Template Name

                After setting up the code and making any necessary changes, be sure to save the file. Then, click the Run button to start executing the program.

                Step 6: Run Program Result

                Great! The program runs successfully and returns the JSON file output. Let’s check the program folder path to view the output.

                Run Program Result

                Step 7: JSON Output

                Here is the JSON output that contains the extracted data from the PDF document.
