Shameless self promotion: preview.ninja is a site I built that does this and supports 300+ file formats. I'm currently weekend coding version 2.0 which will support 500+ formats and allow direct data extraction in addition to safe viewing.

It is a passion project and will always be free because commercial CDR[1] solutions are insanely expensive and everyone should have access to the tools to compute securely.
