Open XLSX files — free, in your browser
XLSX is the spreadsheet format of Microsoft Excel since 2007. LibreOffice Calc, Google Sheets and Numbers open it too.
With the free downloadlink viewer you open a .xlsx file directly in your browser. Nothing is installed, and without an account nothing is uploaded either — when you are logged in, the viewer keeps your file in My files.
Free · no account needed · 100% in your browser
What the viewer does with XLSX files
You view all sheets as tidy tables, without Excel.
Good to know
For a very large sheet the viewer shows the first 5,000 rows and 256 columns; you calculate and edit in the Excel editor.
How it works
- Click Open your XLSX file above.
- Drag your .xlsx file into the window, or click to choose it.
- View it directly in your browser.
