How to export quiz results to CSV and import into Google Data Studio
Exporting quiz results to CSV and then importing them into Google Data Studio lets you visualize learner performance, spot trends, and share insights with stakeholders. This guide walks you through a practical, step-by-step workflow from exporting raw data to building a live report in Data Studio. Expect to spend about 20–45 minutes for an initial setup and 5–10 minutes for routine updates.
Step 1: Locate quiz results dashboard
Open the quiz platform and sign in with an account that has reporting access. Navigate to the quiz results or analytics area, which typically lists attempts, scores, timestamps, and user identifiers—collect these fields because they form the basis of your CSV export.

Step 2: Filter and select the date range
Choose the exact date range or specific quizzes you want to export to limit file size and keep the dataset focused; common choices are last 7 days, last 30 days, or a particular course period. Filtering first reduces manual cleanup and speeds up import into Data Studio.

Step 3: Choose export fields and format
In the export or download options, select CSV as the export format and include these fields: user ID/email, attempt timestamp (ISO format if available), score, max score, question-level results if needed, and quiz ID. CSV is preferred for compatibility and simplicity when importing to Data Studio.

Step 4: Export and save the CSV file
Click export and save the CSV to a clear folder on your computer or cloud storage; name it with a descriptive file name like quiz-results_2026-05-01_to_2026-05-31.csv. Keep a copy for backups and note the file size—files under 50 MB import faster and avoid upload limits.

Step 5: Open Google Sheets and import CSV
In Google Drive create a new Google Sheet and use File > Import > Upload to bring in the CSV. Choose the setting to convert text to columns and detect dates; Sheets will act as a live connector source for Data Studio and allow easy transformations like calculated fields.

Step 6: Clean and structure data in Sheets
Spend 5–15 minutes normalizing column headers, ensuring date/timestamp columns are proper datetime type, and adding a column for percentage score if needed (formula: =score/max_score). Remove duplicates and blank rows so Data Studio reads consistent data types and avoids aggregation errors.

Step 7: Connect Sheet to Google Data Studio
In Data Studio create a new report and choose Google Sheets as the data source, selecting the sheet you prepared. Set the correct data types (date, number, text) for each column and enable refresh options—schedule automatic refresh every 6–24 hours if your source updates regularly.

Step 8: Build visuals and share report
Add score distributions, time-series charts of attempts, and a table with user-level results. Use filters for quiz ID or date range and create calculated fields like average score. Once ready, share the report with stakeholders via link or embed and set viewer permissions to restrict PII exposure.

- Export smaller date ranges (e.g., 7–30 days) to keep CSV files under 50 MB for faster uploads.
- Include an immutable attempt ID column to de-duplicate records during repeated imports.
- Use ISO 8601 timestamps (YYYY-MM-DD HH:MM:SS) to avoid timezone parsing issues in Data Studio.
- Create a master Google Sheet that appends each new CSV import into one tab to preserve historical data.
- Add a calculated percentage column in Sheets rather than Data Studio for clearer auditing.
- Schedule Data Studio refresh no more frequently than once every 15 minutes to avoid API quota issues and unnecessary load.
- Do not include sensitive personal data (full SSNs, passwords); remove or pseudonymize before sharing reports.
- Large CSVs (>100 MB) can fail to upload or slow down reports; split into smaller files if needed.
- Be careful with date/time zones—misinterpreted timestamps can shift results by one day.
- Ensure you have permission to share learner data and comply with privacy policies (e.g., FERPA, GDPR).
