SAV file viewer
Open an SPSS .sav or .zsav file right here in your browser — no SPSS, no installation, no upload. You get the data grid and the full variable dictionary, just like SPSS's own Data View and Variable View.

SPSS .sav or .zsav file
Processed on your device — never uploaded
Data View & Variable View
See the values, then flip to the dictionary: names, labels, types, formats, and every value-label set in the file.
Nothing leaves your device
The .sav is parsed locally by JavaScript. No upload means no exposure — safe for confidential and restricted-use data.
Export when ready
Convert the open file to CSV, Excel, JSON, or a native Stata .dta without re-uploading anything.
Built for files other viewers mangle
The viewer reads compressed and uncompressed .sav files, zlib-compressed .zsav files, UTF-8 and legacy code pages, long variable names, and very long string variables (the 255-byte-plus text SPSS stores in segments). Dates are decoded from SPSS's 1582-based clock into readable form rather than 12-digit numbers.
Working with Stata files too? There's a dedicated DTA file viewer, and converters for .sav to CSV, Excel, and Stata .dta.
Frequently asked questions
What is a .sav file?+
A .sav file is IBM SPSS Statistics' native data format. Beyond the data table, it stores a dictionary: variable labels, value labels for coded categories, display formats, and declared missing values. That's why opening one in a plain text editor shows gibberish.
How can I open a .sav file without SPSS?+
Drop the file on this page. It is decoded by JavaScript in your browser and displayed as a data grid with a Variable View for the full dictionary. No SPSS licence, no installation, no upload.
Does the viewer show value labels?+
Yes. Coded categories can be shown as their labels (e.g. "Strongly agree" instead of 5), and the Variable View lists every variable's complete value-label set. Hover a cell to see the code behind a label.
Can I edit or convert the file here?+
The viewer is read-only, but one click takes the loaded file to the converter, which exports CSV, Excel, JSON — or a native Stata .dta file with labels intact.
Is it safe for confidential data?+
Yes. The file is parsed on your device and never uploaded, which makes the viewer appropriate for IRB-governed or otherwise restricted datasets. It keeps working if you go offline after loading the page.
