Upload your spreadsheet (XLS or XLSX) to the viewer.
The file opens in your browser with all rows, columns, and formatting visible.
Browse through the data — the viewer handles multiple sheets, formulas, and styling.
Spreadsheets have a way of arriving when you least expect them — a budget a colleague emailed over, a price list from a supplier, a class schedule someone exported from Excel. If you don't have Microsoft Office on the device in front of you, opening that .xlsx can feel like a dead end. The Spreadsheet Viewer solves that by displaying Excel files directly in your browser, with every sheet, cell, and number laid out just like it would be in Excel itself — no install, no license, no account.
The viewer keeps the structure of your workbook intact. Multiple sheets show up as tabs you can click through, column widths and row heights are preserved, and the formatting that makes a spreadsheet readable — bold headers, colored cells, merged titles — carries over instead of collapsing into a wall of plain text. Numbers stay aligned in their columns, so a table of figures actually looks like a table rather than a jumble, and you can scroll around a large sheet the same way you would in a desktop program.
It reads the formats people actually send. Modern .xlsx files open instantly, and the older .xls format that Excel used for years works too, so a spreadsheet from an ancient email thread is no problem. That's genuinely useful when you're on a Chromebook, a locked-down office computer, or a phone — devices where installing Excel isn't an option but you still need to check what's inside a file before you act on it.
Because you're viewing rather than editing, you can't accidentally overwrite a formula or nudge a number out of place — handy when someone sends you a carefully built spreadsheet and just wants your eyes on it. And since the file is only processed long enough to display it and isn't stored afterward, sensitive data like salaries, invoices, or customer lists doesn't end up parked on a server somewhere. What you open stays your business.
Using it couldn't be simpler: upload the spreadsheet and it appears, ready to read. There's no conversion step to sit through and no software to keep updated. If you eventually need the data in another form, our other tools can convert the same file to PDF or another format, but when the task is simply to see what's in a spreadsheet, this viewer answers that in a couple of seconds.
It fits the everyday moments where a spreadsheet lands in your lap and you just need to look: reviewing a quote before replying, checking a shared inventory on your phone, or opening an exported report on a computer that has never had Office installed. Any modern browser will do, and the result looks the same whether you're on Windows, a Mac, Android, or an iPhone.
Large workbooks with many sheets and thousands of rows open just as smoothly as a small one, so you don't have to trim a file down before you can look at it. And because nothing is installed, the viewer is ready the moment the page loads — no updates to chase, no add-ins to enable, just your data on screen.
