Questions

Is it safe to convert my .sav file here?

Yes. The file is parsed entirely in your browser using JavaScript — it is never uploaded to a server. That also means it works fine with sensitive research data: nothing about the file or its contents ever leaves your device.

Will I lose value labels or missing-value codes?

No. savtocsv reads the value labels stored in the .sav file (e.g. a "gender" column where 1 = Male, 2 = Female) and lets you export them as text labels, the original numeric codes, or both side by side in separate columns.

Do I need SPSS installed to use this?

No. You only need the .sav file and a browser. savtocsv reads the .sav binary format directly, so you do not need an SPSS license, PSPP, or any other software installed.

Is there a file size limit?

Because the file is read entirely in your browser rather than uploaded to a server, there is no fixed upload cap like the 16MB most server-side converters enforce. Very large files are limited only by your device's available memory.

Is savtocsv free?

Yes, converting and viewing .sav files is free with no signup. If it saves you the $1,188/year SPSS license fee for a one-off task, you can leave a tip via Buy Me a Coffee on the pricing page — that is entirely optional.

Can I convert CSV or Excel back into .sav?

Not yet. Writing a valid .sav file is a much harder problem than reading one, and no in-browser writer exists yet that we trust. It is on the roadmap for a future version; today savtocsv only reads .sav files.
