Welcome to Data Studio
FYX Data's offline data cleaning & analytics studio. Import a file, clean it in one click, and watch your data quality score improve in real time — nothing ever leaves this browser tab.
⭐ Why use Data Studio
- 100% private — your spreadsheet never leaves your browser, nothing is uploaded to a server.
- No login, no sign-up, no daily row limit on the free tier.
- Automatic duplicate detection, including near-duplicates with inconsistent spacing or casing.
- Flags ambiguous data (like DD/MM vs MM/DD dates) instead of silently guessing.
- Export straight to clean CSV or Excel, ready to use.
📘 How to use Data Studio
- Upload a CSV or Excel file, or drag & drop it into the import area.
- Review the auto-detected column types and flagged issues.
- Run the cleaning operations you need — trim whitespace, remove duplicates, fix emails, standardize dates and phone numbers.
- Toggle the preview to compare cleaned vs. raw data.
- Export your cleaned data as CSV or Excel — everything runs locally in your browser.
Pick a preset to auto-configure the cleaning toggles for a common use case. You can still fine-tune before running.
