Data formats, converted and inspected in the browser

Structured data arrives in whatever format the last system used: a CSV export, an XML SOAP response, a YAML manifest, an .xlsx someone attached to an email. This category reads all of them and converts between them.

The spreadsheet and CSV tools are worth calling out. Those files usually hold personal data, and this is one of the few places you can open one without uploading it.
