Not saving your work frequently
Use the download feature regularly to save your progress. While our editor has undo/redo functionality, it's always good practice to save important changes.
Ignoring data format consistency
Ensure all data in a column follows the same format (dates, numbers, text). Use consistent delimiters and quote styles to avoid parsing issues when importing to other systems.
Not backing up original files
Always keep a copy of your original CSV file before making major edits. Download a backup before performing bulk operations like sorting or column deletion.
Overlooking character encoding issues
If you see strange characters, check your file encoding. Our editor supports UTF-8, which handles most international characters and special symbols properly.
Not using keyboard shortcuts
Speed up your workflow with keyboard shortcuts. Use Enter to save changes, Escape to cancel, Ctrl+Z to undo, and Ctrl+S to export your file.
