⚙️ Step 1: Prepare Your Documents

1. Collect long documents in text or Word format
2. Ensure clean formatting — remove unnecessary spaces, headers, or footers
3. Organize multiple documents in a folder for batch processing

📊 Step 2: Set Up Excel for Summarization

• Open Excel and prepare columns for:
• Document Name
• Original Text
• AI-Generated Summary
• Optional: Add columns for keywords, insights, or categories

You can use Python or VBA macros to link Excel with an AI API for automated summarization.

🧩 Step 3: Connect LLMs (ChatGPT) to Excel

1. Install Python and relevant libraries (openai, pandas, openpyxl)
2. Load documents into Python using Pandas:

import pandas as pd
from openai import OpenAI

client = OpenAI(api_key="YOUR_API_KEY")
data = pd.read_excel("documents.xlsx")

def summarize_text(text):
    response = client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": f"Summarize the following text:\n{text}"}]
    )
    return response.choices[0].message.content

data['Summary'] = data['Text'].apply(summarize_text)
data.to_excel("summarized_documents.xlsx", index=False)

1. This approach automates summaries directly into Excel for easy review.

🔧 Step 4: Analyze Summaries

• Use Excel functions to:
• Filter key topics
• Sort by relevance or keywords
