- Rows filter live as you type.
- Copy or Download the table (or the filtered rows).
FAQ
What is the MIME type for a .json (or any) file?
application/json. Search any extension on this page and its MIME type appears instantly, offline — .svg is image/svg+xml, .woff2 is font/woff2, and so on, from the IANA media-type registry.
Why do MIME types matter?
Servers send a Content-Type header so browsers know how to handle a file; a wrong MIME type can make a page download instead of render, or block a script. This reference gives the correct one per extension.
Is anything uploaded?
No — the table is bundled and searched on your device; it works offline.
What's the type for a .docx?
application/vnd.openxmlformats-officedocument.wordprocessingml.document — searchable here so you do not have to memorise it.
