Why Use CSV Lists for File Renaming?

CSV and text file lists provide precise control over file renaming, allowing you to specify exact names for each file rather than relying on patterns or rules. This approach is perfect when you have a predefined list of names, need to match files to specific identifiers, or want to ensure consistent naming across large file collections.

Our free online CSV renaming tool supports various formats and delimiters, making it easy to import names from spreadsheets, databases, or other applications. This method is especially valuable for project management, document organization, and maintaining consistent naming conventions across teams.

Common Use Cases

  • Project Management: Rename project files with specific project codes or identifiers
  • Document Organization: Apply predefined document names from a master list
  • Asset Management: Rename media files with specific asset names or codes
  • Database Integration: Apply names from database exports or reports
  • Team Collaboration: Ensure consistent naming across team members
  • Archive Organization: Apply systematic names to archived files

File Format Support

  • CSV Files: Comma-separated values with optional headers
  • Text Files: Simple one-name-per-line format
  • TSV Files: Tab-separated values for spreadsheet compatibility
  • Custom Delimiters: Support for various separator characters
  • Header Detection: Automatic detection and handling of header rows

Best Practices

  • Ensure your CSV/text file has the same number of names as files to rename
  • Use consistent naming conventions in your import file
  • Preview the mapping before applying changes
  • Keep original filenames as backup if needed
  • Test with a small batch before processing large collections
  • Document your naming conventions for team consistency

Technical Considerations

  • File encoding (UTF-8 recommended for international characters)
  • Windows filename limitations (260 characters, invalid characters)
  • File extension preservation and handling
  • Case sensitivity in Windows file systems
  • Duplicate name detection and resolution
