Best Practices

Before Exporting

  2. Select needed columns: Avoid SELECT * for large tables
  3. Clean your query: Remove test data or filters

Choosing Format

  • JSON: For technical/development use
  • Excel: For business reports and presentations

File Management

  • Descriptive names: Include date and query purpose
  • Organized storage: Keep exports in project folders
  • Regular cleanup: Remove old export files

Troubleshooting

Export Issues

”No data to export”

  • Ensure your query returned results
  • Check that query execution completed successfully

”Export failed”

  • Check file permissions at save location
  • Ensure sufficient disk space
  • Try a different save location

”Excel export not available”

  • Your result set has more than 10,000 rows
  • Excel export is disabled for datasets over 10K rows
  • Use CSV export instead for large datasets

”File too large”

  • Reduce row count in your query
  • Use CSV instead of Excel for very large datasets
  • Apply more restrictive WHERE clauses

Performance Tips

For large exports:
  1. Use row limits: Add WHERE ROWNUM <= 10000 for Excel compatibility
  2. Select specific columns: Avoid unnecessary columns
  3. Choose appropriate format: CSV for data over 10K rows, Excel for smaller reports
