01 / Fast steps
- Drop or select your .xlsx, .xls, .xlsm or .ods files.
- Every sheet is laid out as a scrollable grid you can read straight away.
- Copy the values as text, or download the whole workbook as PDF.
XLSX Viewer
Drop a spreadsheet and read it here: every sheet in a real grid, with lettered columns and numbered rows, no Excel and no Microsoft account. The file is opened inside your browser, so the figures in it stay on your machine.

02 / Best for
- Open a spreadsheet someone emailed you on a machine with no Office licence.
- Check what is inside a workbook before deciding whether to trust it enough to open in Excel.
- Read a budget or a price list on a phone or a Chromebook.
- Get a printable, sendable version of a sheet without owning Excel.
03 / Why here
- Cells keep the formatting Excel gave them, so a date reads as a date and a price keeps its currency instead of showing the raw serial number underneath.
- Column letters and row numbers stay visible while you scroll, so a reference such as D14 in an email still points at the right cell.
- Nothing is uploaded, which matters more here than almost anywhere: a workbook is usually salaries, customer lists or figures that have not been published yet.
- Macros are never run. A viewer that only reads the cell values cannot execute the code an .xlsm carries.
04 / Keep in mind
- Values, not spreadsheets: charts, pivot tables, conditional formatting and cell colours are not reproduced.
- Formulas are shown as the value they last produced, because that is what the file stores; the formula text itself is not displayed.
- Very large sheets are capped at the first 500 rows and 40 columns for the preview, and the page says when a sheet was cut.
- Password-protected workbooks cannot be opened without the password, which this tool does not ask for.

Questions & answers
01What is the difference between XLS and XLSX?
They are two entirely different file formats that happen to hold the same kind of thing. XLS is the binary format Excel used until 2003: a compound file, effectively a small file system holding raw records, which only Microsoft fully documented years after the fact. XLSX, introduced with Office 2007, is a ZIP archive of XML files, one per sheet, following the Open XML standard. That is why an XLSX can be opened by software Microsoft had nothing to do with, why it compresses better, and why a corrupted XLSX can sometimes be repaired by hand while a corrupted XLS usually cannot.
02Why will my spreadsheet not open?
Usually one of four reasons. The machine has no spreadsheet program at all, which is common on a work laptop without an Office licence. The file is an .xlsx but was saved with a .xls name, or the reverse, so the program refuses it before reading a byte. The workbook came from the internet or an email and Excel opened it in Protected View, which looks like a failure but is a safety prompt. Or the file is genuinely damaged, which is what you are looking at if several programs reject it. This viewer reads the file structure directly, so it opens the first three cases without complaint.
03Can I open an Excel file without a Microsoft licence?
Yes, and in more than one way. This page reads the workbook in your browser with no account and nothing to install. LibreOffice Calc opens and edits the same files for free on any desktop. Excel for the web and Google Sheets are free too, but both require an account and, more to the point, require uploading the file to a company server first. If all you need is to read the numbers, staying inside your own browser is the option that involves no licence and no upload.
04Does opening a spreadsheet here upload my data?
No, and this is the difference that matters for this format specifically. Spreadsheets are where salary tables, customer databases, pricing and unpublished financials live. Every cell is parsed by JavaScript running in your browser tab; nothing is transmitted, nothing is stored, and there is no copy of your workbook on any server to leak, subpoena or lose. You can prove it: open the browser network panel, drop a file, and watch that your workbook is never sent anywhere.
05What happens to formulas and macros?
A spreadsheet file stores both the formula and the value it last produced, so this viewer shows you the value, exactly what you would see on screen in Excel. What it never does is recalculate, because that would mean running the file. Macros in an .xlsm are the sharper point: macro code is the classic delivery mechanism for spreadsheet malware, and a reader that only walks the cell records has no path to execute it. Opening an untrusted workbook here is genuinely safer than opening it in Excel.
