About Excel Viewer
Preview spreadsheets (.xlsx, .xls, .csv, .ods, .numbers and more) with preserved cell sizes, merges, and styles. Uses virtual scrolling for large sheets.
How to Use
Upload a spreadsheet file. Switch between sheets via the tab bar. The print button is hidden for virtual tables to avoid printing only the visible viewport.
Performance
Large workbooks automatically use a Web Worker for parsing. Drag column headers to resize (if enabled).
▶Why can't I print an Excel file?
Virtual tables only render the visible viewport, so printing would be incomplete. The print button is hidden for spreadsheets. Export as HTML or download the original instead.
▶Are formulas recalculated?
Cached formula values are shown. The viewer does not recalculate live formulas.
