Text Tools
Review practical Replace a CSV Column examples so you can understand expected input, output, and common patterns faster.
Use this tool to replace one CSV column by header name or 1-based column number. It is useful for fixing bad data, swapping out outdated fields, and rebuilding a column without editing every row manually.
Example pages are especially useful for text tools because they show what good input looks like, what kind of output to expect, and how the tool behaves in common scenarios.
Input
email username john anna name,email,role John,john@example.com,admin Anna,anna@example.com,editor
Output
name,username,role John,john,admin Anna,anna,editor
Useful when replacing a whole field instead of deleting and inserting separately.
Input
2 status active pending id,title,role 1,Book,admin 2,Pen,editor
Output
id,status,role 1,active,admin 2,pending,editor
Supports both header-based and index-based column selection.
Fix: Check the CSV header or use a valid 1-based column number.
Fix: Provide one replacement value for each CSV data row.
Fix: Put selector, new header, and values first, then a blank line, then the CSV.
After reviewing these examples, run the live tool with your own input. If your task involves a follow-up step, the related page can help you move to the next tool in the workflow.
