Recursively changing file extensions on Amazon S3

I have a large S3 bucket with a nested "folder" structure containing among other things .JPG and .jpg files (uppercase and lowercase extensions).

So I need do change .JPG files to lowercase extension.

What is the best way to do it?

You would need to Copy the old objects to the new name, then Delete the old objects.

If it is a one-off, I would create a spreadsheet list of Keys, then write a formula that uses the aws s3 mv command. This performs both a Copy and a Delete:

aws s3 mv s3://bucket/folder/foo.JPG s3://bucket/folder/foo.jpg

Then, copy all those commands and paste them into the Command Prompt / Terminal to trigger the rename.

For a large (over 1000) number of objects, I'd suggest doing it via a Python script that does the Copy and Delete.
