About savtocsv

savtocsv is a small, single-purpose tool: convert an SPSS .sav file to CSV, Excel, or JSON without uploading it anywhere. I built it after noticing that most existing options either upload your file to a server, cap the file size at 16MB, or don't export to Excel at all.

Why it's free

SPSS's own license runs $1,188/year, which is a lot to pay for the occasional task of reading a file someone else sent you. Since the actual conversion work happens entirely in your browser — no server has to do anything — there's no real marginal cost to keeping it free. If it saves you real time or money, the pricing page has an optional way to say thanks.

What it is not

This is not a full SPSS replacement, and it doesn't run statistical analyses. It reads the .sav binary format and gets your data into a format other tools can open. For actual statistics on the free side, GNU PSPP is the closer equivalent to SPSS itself — see the guide on opening .sav files without SPSS for the full comparison.
