Free Excel Viewer for Windows — No Microsoft Office Required

Microsoft Office no longer comes pre-installed on Windows and costs $70+ per year. But you can open and view Excel files on Windows for free — several options exist, including one that requires no installation at all.

Browser-Based Viewer: Open XLSX in Edge or Chrome Without Installing Anything

The fastest zero-install option: a browser-based Excel viewer that works in Microsoft Edge, Chrome, or Firefox. Open .xlsx, .xls, .csv, .tsv, or .ods files directly in your browser. No download, no account, no upload to a remote server.

Features: Multi-sheet navigation, column sorting, row search, stats bar, CSV download

Privacy: Your file never leaves your computer. Everything processes locally in the browser.

This is the best option if you need to view a file quickly or if you are on a work or school computer where installing software is restricted.
