About this tool
Open an Excel workbook and navigate every sheet as a clean grid — parsed locally, never uploaded.
Excel Viewer is a free, browser-based way to open and browse Excel workbooks (.xlsx) without installing spreadsheet software. Upload a file and every sheet is listed as a tab you can click through, with cell contents shown in a clean grid.
The workbook is parsed on your device from the Open XML package — no server, no account, no upload. It is ideal for quickly checking a vendor's export, auditing a report before processing, or reading spreadsheets on a device without Office apps.
