In this tutorial, we will generate personalized student report presentations using self hosted Presenton’s API and a Python script. This tutorial extends Generate a PPT via API in 5 Minutes and shows you how to automate the creation of personalized student report presentations from a CSV file using Python. So, do check it before continuing with this and make sure you have Presenton running locally or any server and you are able to generate presentations with it.

​
1. Prepare Your CSV File

Save your student data as students.csv: 
Name,Final Grade,ECA Participation,Sports Involvement,Quiz Scores,Class Behavior,Comment
Anaya Sharma,88,High,Moderate,92,Excellent,"Balanced performer with high curiosity"
Rohan Mehta,73,Low,None,75,Good,"Needs motivation beyond academics"
Meera Kapoor,94,Moderate,High,96,Excellent,"Academic excellence and team spirit"
Aarav Patel,62,None,None,58,Average,"Struggling across areas, needs focused help"

​
2. Install Python Requirements

You’ll need the requests and pandas libraries: 
pip install requests pandas

​
3. Write the Python Script

Let’s build the script step by step.

​
a. Import Libraries

import os
import pandas as pd
import requests

​
b. Creat presentations directory

os.makedirs('presentations', exist_ok=True)

​
c. Load the CSV

df = pd.read_csv("students.csv")

​
d. Define a Function to Build the Prompt

def build_prompt(row):
    return (
        f"Student Name: {row['Name']}\n"
        f"Final Grade: {row['Final Grade']}\n"
        f"ECA Participation: {row['ECA Participation']}\n"
        f"Sports Involvement: {row['Sports Involvement']}\n"
        f"Quiz Scores: {row['Quiz Scores']}\n"
        f"Class Behavior: {row['Class Behavior']}\n"
        f"Teacher's Comment: {row['Comment']}\n\n"
        "Generate a parent-friendly presentation summarizing this student's academic and extracurricular performance, "
        "highlighting strengths, areas for improvement, and any special notes from the teacher."
    )

​
e. Loop Over Each Student and Generate a Presentation

for idx, row in df.iterrows():
    print(f"Generating presentation for {row['Name']}")
    prompt = build_prompt(row)
    data = {
        "prompt": prompt,
        "n_slides": "8",
        "language": "English",
        "layout": "general",
        "export_as": "pdf"
    }
    response = requests.post(
        "http://localhost:5000/api/v1/ppt/presentation/generate",
        data=data
    )
    if response.ok:
        result = response.json()
        print("Downloading presentation...")
        # Prepend the host to the path
        download_url = f"http://localhost:5000{result['path']}"
        filename = f"presentations/{result['path'].split('/')[-1]}"
        # Download and save the file
        file_response = requests.get(download_url)
        if file_response.ok:
            with open(filename, 'wb') as f:
                f.write(file_response.content)
            print(f"Presentation for {row['Name']} saved as {filename}")
        else:
            print(f"Failed to download presentation for {row['Name']}: {file_response.status_code}")
    else:
        print(f"Failed to generate presentation for {row['Name']}: {response.text}")
Generated presentations will be saved in presentations directory. You may change the URL http://localhost:5000 to the URL of your Presenton instance.
Download complete code from github.

​
4. Run the Script

Save your script as generate_reports.py and run: 
python generate_reports.py
Each student will get a personalized presentation, and you’ll see the download path for each file in your terminal.

​
5. How It Works

  • The script reads each row from your CSV.
  • It builds a detailed prompt for Presenton’s API (see API Reference).
  • It sends a POST request to generate a presentation for each student.
  • The API returns a download path for each generated PPTX.
  • The presentation file is downloaded and saved in presentations folder.
