Three things it does

1

Look

See it as a clean table. Sort, filter, and scan to get the gist of what's in the file.

2

Tidy

Fix typos, drop columns, remove duplicates. Small clean-ups, no formulas to learn.

3

Convert

Turn it into JSON, Excel, or YAML, and check column types at a glance before you send it on.

One clean table. That's the app.

Open a file and this is what you get, a real grid with sortable columns and typed cells, not a mockup.
