I have a 20-30 excel files that I will receive every month. The format of the excel files will remain the same. I have written a python script that takes those .xlsx files, does some data operations, and then converts them into .csv files. These .csv files are then stored in either S3 or redshift.
Is there some way I can integrate my code into the AWS pipeline so I do not have to pay for an AWS service (like lambda) to handle and convert my files?
