How to Reorder, Remove, and Rename Spreadsheet Columns Free

Why Edit Columns?

The export has 30 columns but the import expects 10 in a specific order. Column headers don't match the destination system's field names. Sensitive columns need to be removed before sharing. These column-level operations are tedious in Excel and impossible in a text editor for large files. This tool handles them all.

How to Use Column Operations

1. Open the Column Operations tool
2. Upload your CSV or Excel file
3. Drag columns to reorder, click to rename, or select columns to remove
4. Download the modified file

Everything runs in your browser. Your data never leaves your device.

Common Column Tasks

• Reorder columns — drag columns to match the import template's expected order
• Rename headers — change "First Name" to "first_name" for database compatibility
• Remove columns — strip sensitive data (SSN, phone, salary) before sharing
• Select subset — keep only the 5 columns you need from a 30-column export

Data Cleaning Workflow

Column operations are often the first step in a data cleaning pipeline. Reorder and rename columns to match your target schema, remove unnecessary fields, then use the Remove Duplicate Rows tool to deduplicate. This gives you a clean, properly structured file ready for import.
