Excel Viewer and Editor
Open an Excel or CSV file right in your browser, no Microsoft Excel and no signup needed. View it in a clean spreadsheet grid, edit any cell, add or move rows and columns, then download as .xlsx or .csv. Your file never leaves your device.
How to View and Edit an Excel File Online
Upload Your File
Drag and drop your .xlsx, .xls, or .csv onto the page, or click to choose one. It opens in your browser, never uploaded.
View the Spreadsheet
See your data in a clean grid with column letters and row numbers. Multi-sheet files show each sheet on its own tab.
Edit if You Need To
Click a cell to change it. Right-click a column letter or row number to insert, move, or delete, or drag a header to reorder.
Download
Save your changes as a real .xlsx workbook or a .csv file, ready to open anywhere.
Open and Edit a Spreadsheet Without Excel
Sometimes you just need to open a spreadsheet quickly, and installing Excel or signing into an account for one file is a hassle. This Excel viewer opens .xlsx, .xls, and .csv files straight in your browser and shows them in a familiar grid with column letters and row numbers, so it reads exactly like a spreadsheet you already know.
It is not view-only either. Click any cell to change its value, right-click a column letter or row number to insert, move, or delete it, or drag a header to reorder. When you are done, download the result as a real .xlsx workbook or a plain .csv, ready for Excel, Google Sheets, or Numbers.
The part that matters most: your file is never uploaded. The whole thing runs inside your browser tab, so it is safe to open invoices, client data, and anything confidential without sending it to someone else’s server. There is no account, no watermark, and no daily limit. Files with several sheets open with each sheet on its own tab.
