Here's an example of how you can deploy an AWS Lambda function using CloudFormation. This Lambda function will be triggered when an object is created in a specified S3 bucket, and it will convert all uploaded files to PDF format:
1. **Template Preparation:**
   - Create a new directory on your local machine where you will store the template file and Lambda function code.
   - Write a Python code for the Lambda function that converts files to PDF. Here's a simple example using the `python-pdf` library:
     ```python
     import boto3
     import pdfkit
     s3 = boto3.client('s3')

     def convert_to_pdf(event, context):
         # Extract file name and bucket name from the event
         bucket_name = event['Records'][0]['s3']['bucket']['name']
         file_name = event['Records'][0]['s3']['object']['key']

         # Download the file from S3
         response = s3.get_object(Bucket=bucket_name, Key=file_name)
         original_file_data = response['Body'].read()

         # Convert the file to PDF
         pdf_file = pdfkit.from_string(original_file_data)
         pdf_filename = file_name + '.pdf'

         # Upload the PDF back to S3
         upload_response = s3.put_object(
             Body=pdf_file,
             Bucket=
