Friendly, free data analysis
Making statistics friendlier
Analysing statistics can be hard. We work at learning how to use a program when we should be analysing data. Salstat wants to change this.
Years of experience teaching undergraduates and postgraduates struggling to analyse experimental statistics on computer has showed us how programs should work with people not despite them.
We want people to analyse data with ease through friendly software that augments the way we need to work.

What file formats can Salstat import from?
Salstat was designed to be as friendly as possible. Without being an enterprise-funded project, we are limited in what we can do. But what we can do, we do as well as we possibly can. Salstat can import:
- Comma Separated Values, often in text format. We're on the path for Salstat to adhere to RFC 4180.
- Microsoft's Excel format can be imported. You can select which worksheet to import.
- LibreOffice Calc's spreadsheet format can be imported in the same way as XLS/XLSX.
- From version 8 onwards, Salstat does a great job of import SAS format.
- Salstat can take a HTML file and extract tables of data directly into Salstat - and even from live web pages just by entering the URL. You can select which table to import.
What operating systems?
Windows, Macintosh OS X and Linux
