System Usability Scale (SUS)

GitHub Repository(opens in a new tab)

Collect SUS survey responses, instantly calculate percentile-based scores and grades, and export data directly to CSV or Google Sheets.

Instrument version, scoring, and data handling

Version: Original 10-item SUS with a five-point agreement scale.

Scoring: Composite score from 0–100. Grade and adjective labels are interpretation aids, not part of the original instrument.

Data handling: CSV mode creates a file only on this device; the portfolio server does not receive the response. Google Sheets mode sends the participant ID, condition, item responses, calculated scores, tool name, sheet/tab name, and timestamp to the Google Apps Script /exec URL entered by the researcher. Nothing is sent until the final save action. Completion is shown only when that script returns JSON with success: true (or ok: true) after appending the row.
