Can users upload files into a S3 bucket without frontend experience or users having access to AWS account?

Question

I am looking to create an AWS solution where a lambda function will transform some excel data from a S3 bucket. When thinking about how I'm going to create the architecture background, I need to think of a way where I can get non-technical users, which don't have access to the AWS account, to upload data into a S3 bucket. One possible solution is using an S3 API and creating a UI to allow the users to upload the data. However, I do not have much experience with front end programming skills such as JS and HTML. Are there any other possible solutions we can use?

I've thought about creating a simple UI and using a S3 API to ingest data into the bucket but I do not have front end programming experience.

Some ideas:

• Serve a web page from somewhere (S3?) and have them upload via the browser, or
• Give them a simple program like CyberDuck and they can drag & drop files, or
• Setup the AWS Command-Line Interface (CLI) on their computer and have them double-click a script file to sync local disk folder to the s3 bucket, or
• Use Dropbox and Invoke Lambda Function on New File from Dropbox - Pipedream

The main thing to think about is how you want to secure the upload. For example, do they need to authenticate first, or do you want anyone in the world to be able to upload to the bucket (not a good idea!). Should each user have their own IAM User credentials, or should they authenticate to an application that manages its own logins?

Also, have a think about what you want to happen after they upload the file. If they need to download something after the file has been processed, then you'll need a way to 'give back' the new file.
