About Rename Cols
Bulk rename headers and convert to snake_case for SQL.
Rename Columns lets you bulk-edit every header in one pass instead of clicking into each cell individually.
It can auto-convert headers to snake_case (customer_name instead of "Customer Name"), strip special characters that break SQL column names, and apply find-and-replace patterns across all headers at once.
Category: Cleaning & PreparationCommon Use Cases
- Preparing a CSV for import into a SQL database that rejects spaces or special characters in column names
- Standardizing header naming conventions across files from different departments
- Renaming a single ambiguous header like "Value" to something descriptive before sharing a file
Key Features
- Bulk header renaming with find-and-replace patterns
- One-click conversion to snake_case for SQL compatibility
- Strips special characters and spaces from headers
- Preview headers before applying changes
Run Rename Columns after Trim & Sanitize so you're working with clean structure, then use Schema Detect to validate the resulting column types before importing into a database.
