Open a spreadsheet someone sent you without Excel: on a Mac without Office, a Chromebook, a work machine you cannot install on, or a phone. Every sheet is listed, hidden ones included, and the cells show as Excel formats them - dates as dates, currency with its symbol - with the formula behind any cell one click away.
It reads the file and does not change it. To take the data elsewhere, save a sheet as CSV for another spreadsheet or JSON for code. It is free to use, with no account and no upload limit, and it runs entirely in your browser: nothing is uploaded, and while the page stays open, a feature you have already used keeps working offline.
- Can I edit the spreadsheet here?
- No. This is a viewer: it reads the file and never changes it. Saving as CSV gives you the data to edit in another program, but formatting, charts and formulas do not carry over into a CSV.
- Why does a formula show a value but not recalculate?
- The value shown is the one the spreadsheet saved the last time it was calculated. The viewer reads formulas and shows them, but does not run them, so a file saved before its inputs changed shows the old result - exactly as Excel would before recalculating.
- How do I open a DBF file without dBase or FoxPro?
- Drop the .dbf here. dBase III and IV, FoxPro and Visual FoxPro tables open as a sheet, with numbers, dates and true/false fields as they are, and text read in the code page the table names, so Russian, Greek or Polish names come out right. Save it as CSV, JSON or an Excel workbook. Long text kept in a separate memo file (.dbt or .fpt) is not read: those columns come out empty.
- Can it open a Stata .dta file?
- Yes, from Stata 8 to Stata 18 and later (formats 113 to 119). The data opens as a sheet with the variable names as headings: columns with value labels show their labels (a second sheet has the numeric codes), dates show as dates, and Stata's missing values are blank. A last sheet, Variables, lists every variable with its type, display format and label. Save any of them as CSV for Excel, R or Python.
- Can it open a password-protected workbook?
- Yes, if you know the password. A workbook with an open password is encrypted; the page asks for the password and decrypts it in your browser, so neither the file nor the password leaves your computer. That covers .xlsx, .xlsm and .xlsb from Excel 2007 onwards and .xls from Excel 97 to 2003. The old, weak XOR kind of .xls protection is not undone; Excel or LibreOffice can save such a file again without it. A workbook that is only protected against editing - a sheet or structure password - opens without asking.
- Are charts, pictures and colours shown?
- No - only the cells: their values, formats and formulas. Merged cells show their value in the top-left cell of the range, and the page tells you how many merged ranges a sheet has.
- How big a file can it open?
- The whole workbook is read into the browser's memory, so a file of tens of megabytes is comfortable on a laptop and very large ones can be slow. A sheet shows 100 rows a page, and at most 200 columns.
- What about Apple Numbers files?
- Use the Pages, Numbers & Keynote viewer, which reads .numbers files and can save their tables as Excel or CSV.
