Hi I’m encountering issues with the OpenAI upload files module. it supports a lot of files, but refuses them when the extention is in capitals instead of small letters. Can this be changed so that it also accepts capital extentions (as it is the same file/extention)? ---

You can use the lower() formula to change the entire file name to lower case. Or do some tinkering and change only the extension. ---
