My making this web app had 2 motivations:

- There are many 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.

- The s3 console does not allow querying or viewing files beyond a certain size.

- The s3 console does not give you information about data types of columns in the file.

This uses duckdb behind the scenes to achieve this. All you need is the Golang runtime to run this on your machine.
