CSV Viewer vs CSV Editor: Which One Do You Need?
Learn when to use a read-only CSV viewer, when to edit cells, and how to inspect a file safely before changing it.
Use a viewer when you need to inspect a file without changing it. Use an editor when you need to correct a cell, remove a typo, or make a small manual change before downloading a new copy.
CSV Viewer is useful for checking headers, searching rows, and confirming that an export looks correct. CSV Editor adds inline edits and undo support for browser-sized CSV files.
For larger or repeated changes, use a dedicated transformation such as Find & Replace, Column Manager, Trim Whitespace, or Join CSV Files. Always keep the original file and review the downloaded result before importing it elsewhere.
