  2. 2Edit column names directly or apply a naming convention
  3. 3Download the renamed CSV

Key Features

  • Inline header editing
  • Bulk rename with find-and-replace
  • Case convention presets (camelCase, snake_case, UPPER_CASE)

Tips & Best Practices

  • Use snake_case when preparing CSVs for PostgreSQL imports.
  • The find-and-replace supports regex for advanced renaming patterns.
