A free, no-nonsense way to open documents in your browser — nothing installed, nothing uploaded.
DocSheet started from a simple frustration: opening a single PDF or spreadsheet shouldn't require installing software or creating an account. Every viewer on this site runs entirely in your browser using open-source JavaScript libraries — PDF.js, Mammoth.js, SheetJS, and JSZip — so your files are read locally and never sent to a server.
We built dedicated pages for every common format — PDF, Word, Excel, PowerPoint, images, and plain-text formats like JSON, XML, and Markdown — each with the specific controls that format needs: zoom and search for PDFs, sheet tabs for spreadsheets, slide navigation for presentations.
DocSheet is supported by unobtrusive advertising, which keeps every tool free with no sign-up required.
