What is a QSF file?
The .QSF file extension is most often a Qualtrics Survey File. It contains survey questions, settings, and structural data exported from the Qualtrics research platform. Because .QSF has multiple possible meanings, it can also be an Intel Quartus Prime settings file for FPGA development or a sound bank for Korg synthesizers. We recommend using viewer.online/qsf to identify the actual format of your specific file.
How to open QSF files?
To open a Qualtrics Survey File, you typically import it directly into a Qualtrics account. For Intel settings files, use the Intel Quartus Prime software. If you are unsure what your file contains, viewer.online/qsf analyzes .QSF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it directly in your browser.
Software and Conversion Tools
If you need to transform your survey data, we recommend file conversion to sensible target formats on convert.guru. You can easily convert your .QSF survey into .JSON, .TXT, or .CSV formats for easier text analysis and storage.
Summary
Most .QSF files store text data using standard programming structures. Because .QSF files use the known JSON format, viewer.online/qsf can safely open and display them online, eliminating compatibility problems completely.
