💡 Tip: If opening in Excel, use Data → Get Data → From Text/CSV and set ID columns to Text to preserve leading zeros. Or use the Excel download button for permanent preservation.
Download as CSV or Excel — leading zeros preserved permanently in both formats. Unlike Excel's default import, CleanMyCSV never silently corrupts your data.
Your data is never stored, never transmitted, never seen by anyone but you.
