A self-hosted, better browser interface to preview s3 files. This overcomes the limitation of the s3 console not allowing querying or viewing files beyond a certain size. It also gives you information about the column types. It could be a good use case to present this to non-IT teams in orgs who just want a preview of the data in the files or want to do some simple explorations. Frequently, they are denied access because of the possibility of doing something with confidential data via the s3 console.
