I have some BUFR files from METEOSAT satellites. Does anyone know how to read them? An example file is – File Link

I tried reading all the files using-

import os
from pybufrkit.decoder import Decoder
from pybufrkit.renderer import FlatTextRenderer

# Path to the directory
directory_path = '/data/swadhin/meteosat'

# Initialize the BUFR decoder
decoder = Decoder()

# Initialize the renderer for readable output
renderer = FlatTextRenderer()

# Loop through each file in the directory
for filename in os.listdir(directory_path):
    if filename.endswith('.bfr'):
        file_path = os.path.join(directory_path, filename)
        with open(file_path, 'rb') as file:
            bufr_message = decoder.process(file.read())
            # Render the BUFR message in a readable format
            rendered_message = renderer.render(bufr_message)
            print(rendered_message)

But I am unable to make anything out of this. I am new in handling the BUFR files. Is there any structured way of processing this and save the output to an other format(e.g., CSV)?
