Open an SPSS file without SPSS

A .sav file holds more than numbers: variable labels, value labels, formats, defined missing values and often a weight variable. That structure is what makes the file so useful in market research. It is also why the content is so hard to reach without SPSS.

The inspector reads the file locally in your browser and shows the full codebook: every variable with its label and type, plus frequency tables with value labels and statistics like n, missing count, mean and range.

• Weight variable and file encoding are detected automatically
• Numeric and string variables, formats included
• Reads large files with hundreds of thousands of cases

Without an SPSS license, a few roads lead into a .sav file: PSPP, an open-source desktop program; R with the haven package; or online converters. With converters, though, your raw data ends up on a third-party server, which is exactly what most people want to avoid with survey data.

For a first look, the inspector is the fastest way: nothing to install, nothing to upload. And once viewing turns into proper analysing, you simply take the same file with you into DataLion.

The inspector tells you what is in the file. What the data says is something you find out in DataLion. On import, variable and value labels carry over automatically and the weight variable is applied. From there you build weighted crosstabs, run significance tests and share finished dashboards, all without syntax.

The first 14 days include the full feature set. How the analysis works step by step, from missing values to the slide deck, is in the guide How to analyse an SPSS file without SPSS.
