Online Excel Reader:
Open Spreadsheets Without Excel
Upload an Excel or CSV file to view sheets and table data directly in your browser. No desktop Excel installation required.
Local & Private
Spreadsheets are parsed in your browser, so sensitive data stays on your device.
Sheet-Aware Preview
Open XLSX, XLS and CSV files, then switch between individual sheets or the merged workbook view.
Search, Copy, Export
Search spreadsheet text, copy extracted data, or download a TXT version for quick review.
Open Excel and CSV Files Without Installing Excel
A lightweight spreadsheet viewer
The Excel reader lets you open XLSX, XLS, and CSV files in the browser when you only need to review rows, check values, or copy extracted table content. It is intentionally simpler than a full spreadsheet editor.
Sheet selection for workbooks
For multi-sheet Excel workbooks, you can switch between individual sheets or view the workbook as merged text. This keeps quick audits and data checks focused without opening a desktop spreadsheet app.
Good for exports and reports
CSV exports, traffic reports, inventory lists, and lightweight data tables are common cases where a browser preview is enough. Search and TXT export help when you need a fast way to pull values into another workflow.
Use comparison when versions differ
If you need to know what changed between two spreadsheets, use the spreadsheet comparison tool. The reader is for opening one file; the compare tool is for finding differences between two files.
