Document Viewers
Open anything, install nothing
Open PDF, Word, Excel, PowerPoint, CSV, Markdown, JSON, XML and plain text files directly in your browser with search, zoom, page navigation and printing.
The everyday problem is not opening one format — it is being sent something and not having whatever produced it. A spreadsheet arrives and there is no Excel on the machine; a deck arrives on a phone; a colleague sends a .json and the browser offers to download it rather than show it.
Every viewer here reads the file in the page you are on. Nothing is installed, no account is created, and the file is not uploaded to be rendered — which is what makes these safe to point at a document you would not email to a stranger.

Which one do I need?
- I do not know what this file even is
Universal Document Viewer - A spreadsheet, and it is very large
Excel (XLSX) Viewer - A .docx, on a machine with no Word
Word (DOCX) Viewer - A CSV, without a spreadsheet reformatting it
CSV Viewer - A log file too big for a text editor
Text & Log Viewer - An HTML attachment I do not trust
HTML Viewer
Worth knowing
These are readers rather than editors, and the distinction is deliberate: a reader can open a very large file quickly and cannot damage it. Where a format has behaviour as well as content — a spreadsheet macro, a script in an HTML page — it is not executed here, which is the point rather than a shortcoming.
