Previewing an object

Open an object and it renders in place, with the viewer its format deserves — no download, no temporary copy, no second application.

The parser runs in a worker on your machine, reading the bytes the provider streamed back. That is true of every format in the list, from a 40 KB parquet file to a multi-gigabyte object opened in hex.

What decides the viewer

The extension, and then the bytes. A file with no extension, or a wrong one, is sniffed: the first bytes decide, which is how a .hoodie folder is read as a Hudi timeline and a .DS_Store as the binary plist it is.

The toolbar

The icons on the right of the breadcrumb switch what the same object is shown as:

View	the format's own viewer — a grid, a page, a picture, a waveform
Hex	the bytes, always available — see hex
Structure	the file's internal shape, where a format has one
Share	hand the rows to somebody — see sharing a table
Refresh	ask the provider again
Info	size, class, first seen, how often it was read

A tabular object opens as a notebook instead: the grid is the first cell's output, and there is a query above it.

Next: column summaries.
